Complete Blood Count (CBC)

How is the complete blood count test (CBC) done?

The complete blood count (CBC) test is performed by obtaining a few milliliters (one to two teaspoons) of blood sample directly form the patient. It can be done in many settings including the doctor's office, laboratories, and hospitals. The skin is wiped clean with an alcohol pad, and a needle is inserted through the area of cleansed skin into to patient's vein (one that can be visualized from the skin.) The blood is pulled from the needle by a syringe or by a connection to a special vacuumed vial where it is collected. This sample is taken to the laboratory for analysis.
