CMP Blood Test Vs BMP Blood Test Explained

What is CMP Blood Test?
CMP letters stands for: Comprehensive Metabolic Panel (CMP)
and mean: A collection of laboratory tests to show how well is your body metabolism generally.
Medical lab terms: CMP Chem 12 Chemistry Panel Chemistry Screen SMA 12 SMA 20
What is BMP Blood Test?
BMP letters stands for: The basic metabolic panel (BMP)
which mean: A package of laboratory test to help doctor know the current status of a person’s metabolism,
Laboratory short forms:  BMP Chemistry Panel Chemistry Screen Chem 7 SMA 7 SMAC7 electrolyte panel
What type of tests included in C M P test Panel?
14 measurements include:

  1. Albumin blood test level: measures how well your liver is making the proteins that your body needs.
  2. Alanine aminotransferase (ALT) level ALT is a liver enzyme specific for liver cells disorders.
  3. Alkaline Phosphatase blood test: for highly damaged liver cells..
  4. Aspartate aminotransferase (AST) blood test: aid with ALT test to diagnose liver diseases.
  5. Blood urea nitrogen (BUN) blood test: As kidney function decreases, the BUN level rises.
  6. Calcium blood and urine tests: for kidney stones and well excretion of excess calcium.
  7. Carbon dioxide (Bicarbonate) – Your kidneys and lungs balance the levels of carbon dioxide, bicarbonate, and carbonic acid in the blood. Carbon dioxide levels can be used to help diagnose kidney disease.
  8. Chloride test: it is an electrolyte, high chloride indicate kidney disease.
  9. Creatinine blood test: measure of how well the kidneys are removing wastes and excess fluid from the blood.
  10. Glucose blood levels: Renal glycosuria occurs when the renal tubules fail to reabsorb all glucose at a level that is normal.
  11. Potassium blood test: an electrolyte when high refers to Kidney disease.
  12. Sodium blood level: useful to know if the kidneys are properly removing sodium from the body or not.
  13. Total bilirubin blood test:high level means obstruction in liver and appear as yellowish skin and eyes which is called jaundice.
  14. Total protein:measures the amount of protein in your blood. The two main proteins found in the blood are globulins and albumin.

4 Calculated Tests in CMP test panel:

  1. Albumin/Globulin Ratio (calculated): The A/G ratio
  2. BUN/Creatinine Ratio (calculated): high level means a decrease in the flow of blood to the kidneys.
  3. Globulin (calculated) blood test: Low globulin levels can be a sign of liver damage or other conditions.
  4. Estimated GFR blood test: A GFR below 60 is a sign that the kidneys are not working properly. A GFR below 15 indicates kidney failure.

What type of tests included in B M P test Panel?
8 measurements most of them are electrolytes.

  1. Calcium blood test.
  2. Carbon dioxide test: measure of how well your kidneys and lungs are working.
  3. Chloride test measure related to how your body manages fluids.
  4. Creatinine levels can tell how well your kidneys are working.
  5. Glucose blood level: how much sugar is in you blood
  6. Potassium test
  7. Sodium blood levels measure if your blood cells have enough water to work well.
  8. Urea nitrogen, or BUN


Is fasting required for a CMPand BMP blood test?
Fasting is required for the blood glucose test that is included in the CMP and BMP
Fasting for a blood test is defined as no consumption of food or beverages other than water for 6- 10 hours before testing.
