hcg levels

meaning of hcg

Is BHCG less than 5.0 considered a Positive or a Negative Pregnancy Test Result?

Many women sent such results to the Facebook page’s inbox, like this

The medial laboratory interpret the BHCG levels like that:

  1. Beta hCG < 5.0 mIU/mL, any hCG number less than 5 means that there is no pregnancy yet or that the pregnancy is still very early and at its first beginning, and therefore the level of the pregnancy hormone appears very little to a degree less than 5.
  2. Beta sub-unit from 6 up to 24, an hCG number in this range means that pregnancy is at its beginning and that the pregnancy hormone still needs more time to increase and rise, so we have to repeat the B-hCG blood test again after at least 48 hours to make sure that the pregnancy hormone increases as time passes. Also after re-doing the quantitative hCG test, if the hormone level increases, then this is a good sign of the continuation of the pregnancy, but it cannot be considered evidence of the viability of the pregnancy. Know why. But if the pregnancy hormone level has stopped increasing to a remarkable number or becomes less than the result of the previous test, then this is a very important sign of the end of pregnancy and the loss of the fetus in the very early stage.
  3. If Quantitative hCG test result >25, <100, any hCG number equal to or greater than 25 is considered a pregnancy from the first test, but this hCG number must double every 48 hours, and that the menstrual cycle must be delayed by a day or two at the most so that the result can be interpreted as a pregnancy at an early beginning. Practically we find most hCG readings between 25 and 100 in the first days after delayed menses often go down which leads to pregnancy loss, so that your doctor may prescribe progesterone supplements to increase the hCG level in the pregnant’s blood and to help maintain a healthy pregnancy.


B-hCG < 5.0 usually means negative pregnancy test, but if the date of menses is still early, the hCG lower than 5 may mean a very early pregnancy, that’s because the hCG hormone can be detected 6 days earlier before the due date, and therefore you must repeat hCG test after the menstrual cycle is late than the usual date every month, and this repetition is to make sure that HCG 5 increases and that it was due to very early pregnancy.

Also, hcg <5 can be seen if the woman is in premenopausal (before girl puberty) or postmenopausal stage (usually after age 50 of women there’s no menstruation), it means the girls before menopause may normally show b-hcg number lower than 5, and women stopped their menstruation can still naturally see hCG number lower than 10 without pregnancy or any disease.

Note that some tumors can see slowly increasing hCG levels, but this is another article, be tuned.

10 Blighted Ovum HCG Levels Must Know

Blighted ovum HCG levels with doubling time and rising levels of the pregnancy hormone.

From real case’s complications:

  • A woman done her first pregnancy test and show a faint line which means weak positive pregnancy.
  • After a week, cramps and slight bleeding.
  • In the emergency ward at the local hospital, the Gynecologist done an internal ulstrasound and can’t see any sac.
  • She told the doctor that she’s in the week 6 and 3 days.
  • At the clinic one day later, the Gunecologist repeated the ultrasound scanning with transvaginal probe and found a little white speck in the sac.
  • Tomorrow at laboratory: take a quantitative beta subunit HCG blood test and the results show rising HCG levels at 5 weeks and 5 days post LMP.

The woman told me that she was worried and confused about the conflicts of BHCG levels and ultrasound.
The first doctor recommended methotrexate upon diagnosis as ectopic pregnancy but the second doubling HCG blood test with white dot sac suggests a blighted ovum which require a dilation and curettage procedure.
What’s the opinion of medical science?

What blighted ovum is?

A blighted ovum is an early pregnancy failure after the fertilized ovum attached to the uterine but failed to develop an embryo even after 14 week LMP. That’s why I have blighted ovum pregnancy?

When blighted ovum is occurred during the pregnancy?

A blighted ovum occurs during the early pregnancy term (the first trimester), may be the woman didn’t know that she’s pregnant yet.

Do HCG levels double with blighted ovum?

Blighted ovum HCG levels still rise and high but not doubling enough as in normal pregnancy, blighted ovum symptoms is the same with normal pregnancy. lack of symptoms of blighted ovum is common.
From a real blood work for a pregnant women:

At 5 weeks

HCG level 680, after 48 hour HCG level 1800, no sac on ultrasound, no bleeding and no cramps.
Had a blighted ovum?
Answer: The case is for a normal pregnancy till now and the time scale can’t tell the right expectation, the advice is to wait until the week 8 at least.

At 20 weeks:

blighted ovum HCG levels
Ultrasound noticed one inch empty sac, still feel pregnant even blood pregnancy test is negative and urine pregnancy test is negative too.
Felt a baby in my belly, discharges from my breast when squeezed.

Can be a blighted ovum even after 12 weeks?

The Answer: A small sac with nothing in it and HCG level below 5 units after 5 weeks must refer to a blighted ovum. You had missed miscarriage. Get the Ob/Gyn advice for natural miscarriage or by D&C operation.

What to do for blighted ovum management?

If your body still acting as you’re pregnant, doctors would recommend to wait few days until the body passes this anembryonic (no embryo) pregnancy naturally.
And can conceive as close as the next week, as the period is due within a month and HCG levels can back after nearly two weeks.
If you’ve blighted ovum conception your doctor will have two options, the pills or surgery.
You shouldn’t be scary of D & C, it’s for your safety. The sac would expel by it’s own but remnants in the uterine may cause infection, so that the D & C would be beneficial to avoid complications.
But woman must wait three consecutive cycles before trying to conceive again, the reason is to allow the uterine lining to rebuilt itself in the way to sustain another pregnancy.

What to do with blighted ovum hcg levels and ultrasound?

Blighted ovum is difficult to see on ultrasound until the week 10 LMP.
Blighted ovum HCG levels 5 weeks LMP is within expected levels for normal pregnancy.
Even with no embryo inside the sac the placenta and corpus luteum continue to produce pregnancy hormone at early pregnancy.
At week 4 and 5 a yolk sac and fetal pole but no heartbeat, heart beat is the baby’s life determining factor inside you.
You would find heart beat after week 11, and only babies with heart beat deemed live.
See: HCG level ultrasound and heart beat chart

What to do for blighted ovum with HCG levels rising?

Most woman scarred after week 9 with no bleeding or pregnancy, so please understand first.
If you have or expect a blighted ovum just relax and retest BHCG blood test and ultrasound until the week 12.
Confirm blighted ovum after week 14 with low HCG levels, no visible embryo sac, and no heart beat.
Never rely on the sac size small or big or how sac is measuring when it’s empty.

When do hcg levels drop with blighted ovum?

From 4 to 7 weeks and up to 12 weeks for some women after a successful m/c or d/c operation, beta subunit HCG test after d/c can predict the dropping rate of HCG levels after blighted ovum miscarriage.

High B-HCG Levels and No Image on Ultrasound, What to expect?

How to deal with the confusing problem of not seeing the baby on ultrasound while your hcg blood test say you’re pregnant, how to avoid delay diagnosis of baby? how to protect yourself from misdiagnosis at early pregnancy?
firstly, you must know why pregnant do sono early?
The purpose of the scan is:

  • to confirm that there is a heartbeat
  • to assess the baby’s size and growth
  • to estimate the delivery date and
  • to check whether there is one baby, or twins or more.

What is the best routine ultrasound scan of pregnancy?
There are two ways of doing an ultrasound scan for pregnancy:

  1. Trans-vaginal (internal) scan: where a probe is safely placed in the vagina, accurate and clearer early picture. useful before 11 weeks for earlier detection, and after 12 weeks if a trans-abdominal scan doesn’t give a clear enough sono picture.
  2. Trans-abdominal scan: useful from 11-12 weeks and at the routine booking-in scan, at early pregnancy it’s less clear than an internal scan and that could delay diagnosis. the woman doing the scan spreads a special gel on the lower abdomen specifically below your belly button and above the line of pubic hair, the doctor then moves the scanner over the gel, sometimes pressing down, until the womb (uterus) and pregnancy can be seen.

Is ultrasound scan do work to detect pregnancy without the hcg blood test?
No, both are used to detect and confirm the progress of pregnancy, although the hcg test results may come up with the earlier sign of pregnancy as closer as 7 days after ovulation and successive implantation which is much more than ultrasound scan do, at 6 weeks of gestation hcg level is well detectable but sonogram is a bit unclear until the week 8, however hcg results only can’t confirm a viable pregnancy until a sac and heartbeat can be clearly detected on the sonar screen.
what to expect from the heartbeat results?
As long as there is a heartbeat, the risk of miscarriage decreases as the gestational weeks go by.
You will asked to repeat the scan and beta subunit hcg if:

  • There’s a heartbeat, but I’m still bleeding? Then check your beta subunit hormone, FSH, LH, E2, and Prog. levels and repeat ultrasound after few days, if ok, then progesterone medication may be suitable.
  • if the pregnancy is too small for the heartbeat to be visible, or there may be nothing much to see at all and it’s not clear what is happening, then retest and rescan after 1-2 weeks for the results to be clearer.high beta hcg levels ultrasound no image

7 weeks and no image on sono, no heartbeat, no sac, low hcg levels, what to expect?
Your doctor thinks you might have an ectopic pregnancy or silent miscarriage, take blood tests and/or a laparoscopy.
Remember that: An ectopic pregnancy is a medical term for a pregnancy that is developing outside the uterus, usually develop in one of the Fallopian tubes or inside the abdomen.
Hydatidiform Mole/molar pregnancy: where the cells of the placenta grow very quickly while the baby can’t develop. difficult to be diagnosed on scan so you might find out only after the miscarriage.
let us take this pregnancy quiz to discover why pregnancy hormone is normal but the baby not showing in Ultrasound scan?
Suggested causes and solutions:

  • Recalculate your ovulation days and gestational age.
  • Repeat HCG blood test after a week and rescan ultrasound, have you got a strong baby heartbeat and a sac on the monitor? have your bhcg count raised?
  • In the early pregnancy at 6 weeks gestation, the developing embryo show on monitor is very small because the baby is only 5-9mm long or may be smaller in many cases,  to get a better image of the baby on sonar at early pregnancy ask your doctor to use transvaginal ultrasound, Asking your doctor to scan your vagnia with vaginal probe to see any smaller mass is not difficult and not hurting, nevertheless, is more accurate to detect the baby than the abdominal probe.
  • Sudden unplanned miscarriage may be suspected if you had bleeding, the best indicator of abortion is the vaginal bleeding not spotting, although ultrasound scan may show dies baby some weeks earlier than visual bleeding and any pain. The medical term for this is “missed” or “delayed” miscarriage. This can come as a considerable shock and need a difficult medical decision by your doctor.
  • If dates are correct and no bleeding then check if there is irregular past periods or interrupted menstrual period due to hormonal imbalance, take blood tests for progesterone, LH, FSH, TSH and E2, if all are within expected ranges then it’s ok.


  1. hcg levels 1600 and no image on sono? if HCG hormone count is normal, no bleeding from vagina, but still no heart beat or image seen on ultrasound, you may be diagnosed earlier or you have abnormal pregnancy, waiting 10 days on average is the ideal solution.
  2. Bhcg levels 15000 and no image on sono? it is a risk of ectopic pregnancy, use vaginal ultrasound and retest the beta hcg.

The hcg levels chart for viable pregnancy at 6 weeks from LMP (gestational age) :

  • 3 weeks LMP: 5 – 50 mIU/ml.
  • 4 weeks LMP: 5 – 426 mIU/ml.
  • 5 weeks LMP: 18 – 7,340 mIU/ml.
  • 6 weeks LMP: 1,080 – 56,500 mIU/ml.

20+ real cases, AM I PREGNANT , all pregnant or non pregnant questions answered

Am i preggo or not?
This question does not mean have a bun in the oven or in a family way, the preggers, preggo, prego, pregos is a slang of “pregnant”

Firstly the “HCG” stands for Human chorionic gonadotropin (HCG), a protein hormone that stimulates progesterone secretion, appears in biological fluids as intact HCG, free α subunit, free β subunit, and various fragments such as nicked HCG and nicked free β HCG.

The pregnancy scenario will be as follows:
The story of pregnancy starts:

  • From the day one to the fifth of LMP: Women riding the Crimson wave this week (menses) and an ovary generated a follicle released by the day 3 in the fallopian tube.
  • Up to the day 13 of LMP: the follicle develops an ovum that becomes dominant by the day 14 and ready to be fertilized.
  • 14 days later: the uterus is ready to receive the fertilized ovum, if there is fertilization, then the fertilized ovum emigrating to uterus within 7 to 10 days after conception and implanted there, if no fertilization occurred, then the ovum and the uterine lining emerge through the menstruation at the end of the cycle period as Aunt Flo and cousin Red came to visit.
  • HCG Beta subunit rise from 5 ml/l in the beginning of gestation to become multiplied every day to be in the detectable range within 6 – 8 days in blood sample and up to 10 days in the other specimens.

By understanding the pregnancy story and B-HCG levels chart every woman can calculate the gestational age easily.

HCG Levels throughout Normal Pregnancy
HCG is secreted by the trophoblast in increasing amounts from the time of implantation of the fertilized ovum (blastocyst) in the uterine endometrium.

Simply HCG is the hormone growing the implanted fertilized ovum until the progesterone hormone increased in the yellow body or what scientifically called corpus luteum. Progesterone develops the placenta, while placenta being developed by the hormone progesterone, the hCG hormone declined by the week 6 – 8 of the gestation date. And the placenta takes the responsibility to feed and growing the embryo.

HCG levels Chart in different pregnancy types
General HCG beta subunit charting added which show the multiplying level of hcg hormone over the age of pregnancy, hcg give us a strong sign to progression of pregnancy and viability of gestation.
1. IUI and IVF: must still double after 15 days, otherwise there is non-viable pregnancy.
2. Early miscarriage: Pain with strong fall of B-HcG level.
3. Ectopic pregnancy: Pain in the wrong gestation area, B-HCG level rise in slow curve tend to stop or fall.

What I do to test for pregnancy?
What I do to know if I am pregnant or not?
Calculate your period carefully, if you are in the right date and NO cycle yet, and then go to the lab for checkup.
home pregnancy testWhen comes to lab do not forget to tell the Lab phlebotomists or Lab specialist who are doing the sampling and blood testing, if you are pregnant, and what pregnancy trimester you are in at the time of the test, or what your menstruation date for that time, of course to recommend you the best test for you.

Pregnancy test one pink one white am i pregnant?
Usually a questions like “I took a pregnancy test one line dark pink and one white line am i pregnant?” arise and here the answer

Wait 6-8 days after your period stopped and after conception, if you are pregnant, the blood pregnancy home test will give you 2 lines whatever they are faint or sharp colored, or wait 7 – 10 days to get a Positive pregnancy test in your urine sample.

Late Period or pregnant?
If your menstruation stopped and you did not see any blood at the time of next menstruation date, then you may be get pregnant or have a problem in your hormonal rhythm, go to the Lab and tell them the whole data.

15 days after your menstruation blood not seen and NO Positive pregnancy test appear either in blood or urine, then your are facing interrupted menstruation, and must go to a gynecologist to get treatment, and sure you are not Pregnant.

Frequent blood drops after Positive Pregnancy test?
Missed period by day or two and you are see some blood drops as not usual after some days of stopped or missed menstruation.
Pregnant women do not get periods: continues blood after missing it for some days means your certainly NOT PREGNANT

Recommended to check the abdomen by U/S ultrasound with an immunoassay pregnancy test, If hcG subunit test was Positive, I mean b-hcG is of any value above 5 mIU/mL, and U/S Sonar give NO appearance of gestation on the screen “both sacs and fetal pole”, those results with the bleeding is a strong sign of early abortion due to hormonal problems.
You are made hard work at home, or may be due to immunological causes, anyway start treatment with fixative progesterone supplements and multivitamins with eating fruits which rich with minerals. The bleeding should stop, and the cramping too after some days later. Yes, Successive implantation. Then you are surely Pregnant. Follow up.

Early miscarriage or just an interruption?
Missed period then blood drops seen after some days with cramps and backpain “backache” usually with pain in one breast or in chest area, those signs continues after Positive Pregnancy test means YOU are suffering from early abortion. The fixatives may not be beneficial any more. Sorry to tell you that the Implantation failed and there is no pregnancy and still not Pregnant.

Excessive discharges in the early days of pregnancy?
Getting white discharge with cramping after successive implantation, does not means interruption in the pregnancy, ask your doctor for checking the discharges up.

I missed my period and pregnancy test still NEGATIVE?
I’m feeling delicate 3 days ago and still the pregnancy tests appear negative, but I feel I am pregnant; you need to have another beta done in 48 hours from when you took the first test. If the number detected and doubles, you still pregnant otherwise your doctor may start medication.

Continues menstruation bleeding with Positive Pregnancy test?
Different examples:
I am 11 days late heavy boobs light pink bleeding bright red little cramping am i pregnant?
Bright red blood when i wipe but not in toilet am i pregnant
If the women got the painters in or in her flowers (menstruating) and the pregnancy test came positive:

  1. Bleeding at the time of period cycle considered menstruation.
  2. Positive HCG hormone test means pregnancy.
  3. Need to carry out B-HCG beta subunit quantitative analysis with imaging investigations to exclude a benign tumor in uterus.

If i am not ovulating am i pregnant

  1. Calculate your ovulation day carefully then
    go for a pregnancy test.
  2. If you never ovulated before, a tumor or hormonal disturbances are suspected.

When the Qnt B-HCG testing must be done?
Follow up Normal Pregnancy of the main goal of requesting the B-HcG level, but it is a very strong tool allows doctor to decide ending or keep pregnancy session, such as:

  1. Missed period but negative pregnancy test.
  2. Continuous bleeding at a non-proper time as in child girl under menstruation age or due to cancerous tumors.
  3. Interrupted pregnancy at whatever time.
  4. Suspected Pregnancy false positive and false negative results with rapid screening test.
