Clinical Info:
The CBC or Complete Blood Count test is one of the most commonly ordered laboratory tests. This test is a profile that is designed to check for many different medical conditions. This test may be used as a screening test as well as a diagnostic test. The test is designed to check for the three major types of blood cells: Red blood cells (RBC) or erythrocytes, white blood cells (WBC) or leukocytes and platelets or thrombocytes. The test will also perform an automated differential to differentiate the different cells within each category. In some cases, and where warranted a manual differential count will be performed where the hematologist will make a thin-smear slide of the patients' blood and confirm or adjust the automated findings. Obvious blood parasites such as malaria and babesia may also be noted during this exam, but if you suspect a patient to have a blood parasite, please order SAL# 1070.
Additional Information:
This test is very useful as a screening test to evaluate overall health; detect and/or identify a wide range of hematologic disorders; assist in managing medications/chemotherapeutic decisions.
