Routine Lab Tests
Here are the commonly ordered lab tests by physicians today. All lab values have
a normal range. They can be high, low or normal. If you go in for a complete
physical exam, here is what you are likely to get:
CBC (complete blood count) The various cells in the blood are counted and
tabulated. White blood cells: There are five types. One type (neutrophils) are
elevated in bacterial infection. The count can otherwise be altered in leukemia
or rare blood diseases. White cells are part of the immune system. Red blood
cells: Carry oxygen to the cells. Low in anemia. Anemia is RARELY a cause of
fatigue. Hemoglobin: The stuff in the red cells that binds to oxygen. Low in
anemia, by definition. Hematocrit: A measure of total red cell volume. MCV, MCH,
MCHC are just various ratios of the above values. Platelet Count: Platelets form
a clot to seal off a wound from bleeding when it first occurs. Differential:
This is the percentage of the various types of white cells: lymphocytes,
mononuclears, neutrophils, eosinophils, and basophils.
