Question: My ESR test was 100. Can you tell me what that means, Said it should not be more than 20

Answer: ESR is the abbreviation for ” erythrocyte sedimentation rate”, a lab test used for knowing if the inflammation exist or not, and if already exist the ESR results tell us how much is the inflammation and if the treatment plan is working or not?

The normal level of ESR test is 0 to 20 after an hour, and normal ESR means no inflammation inside body or the inflammation isn’t cause any effect on the Erythrocytes sedimentation.

If the ESR is greater than 100, it is a very high ESR level and indicates chronic or prolonged inflammation episode.

When to use PSA ratio correctly

Q: Can PSA Free Ratio Be Normal While I have Prostate Cancer?

Question: And what about Total 8.4 and Free 2.3 on established prostate cancer. PSA total was 4 less than a month ago, free wasn’t tested then.

Answer: The Free PSA according to your numbers is about 27% which carries a little risk of cancer, but must confirmed with other DRE with symptoms and MRI.
As you wrote, PSA 4.0 is a borderline which means you must retest within few months to make sure it will not increase.

About 15% of men with normal PSA (less than 4.0) can have prostate cancer.
Free PSA% can only filter some cases to minimize the waiting list for surgical biopsies.
And therefore, PSA test is only one tool to judge on the prostate enlargement and not the only one.

The secret key for correctly using PSA in diagnosis of prostate cancer is the follow-up to know if the PSA level increasing or not.
