Complete Blood Count (CBC) Test



The most comprehensive test of the immune system. This complete blood count (CBC) measures white blood cells and platelets, which are involved in clotting, and hematocrit — the concentration of blood.

The white blood cell count is examined under a microscope to determine the levels of these cells:

Lymphocytes, such as T and B cells, direct the entire immune system and make antibodies to fight infections.

Neutrophils, cells normally seen in pus, are the first line of attack against invading bacteria and other infections.

Eosinophils , usually found in very small quantities, are known to be important in allergic disease such as asthma or drug allergies. They are also elevated with conditions such as systemic lupus, cancer, or parasitic infection.

Basophils, similar to eosinophils, can also be found in allergic and other diseases.

The Complete Blood Count (CBC) with Differential and Platelets Blood Test contains 1 test with 33 biomarkers s used as a screening test for various disease states including anemia, leukemia and inflammatory processes.

*Only available in the US, excluding New York, and requires a blood draw at a local Quest lab
