Test ID CBC Complete Blood Cell Count (CBC) with Differential, Blood

Reporting Name

CBC with Differential, B

Useful For

Screening tool to confirm a hematologic disorder, to establish or rule out a diagnosis, to detect an unsuspected hematologic disorder, or to monitor effects of radiation or chemotherapy

Reflex Tests

Test ID Reporting Name Available Separately Always Performed
DIFFR Morphology Eval (special Smear) No No
PINTP Peripheral Smear Interpretation No No

Testing Algorithm

A morphology evaluation is performed at an additional charge when the automated 5-part differential is invalid or when abnormal results are identified upon microscopic examination.

 

A peripheral blood smear review is performed at an additional charge when pathologist expertise is needed for clinically significant diagnosis.

Clinical Information

RBCs, WBCs, and platelets are produced in the bone marrow and released into the peripheral blood. The primary function of the RBC is to deliver oxygen to tissues. WBCs are key components of the immune system. Platelets play a vital role in blood clotting.

 

Mean corpuscular volume (MCV) is a measure of the size of the average RBC. Anemias are characterized as microcytic (MCV <80), macrocytic (MCV >100), or normocytic. The red cell distribution width (RDW) is a measure of the degree of variation in RBC size (anisocytosis). RDW may be helpful in distinguishing between some anemias. For example, iron deficiency anemia is characterized by a high RDW, while thalassemia is characterized by a low RDW.

 

These counts are used as clinical guides in the diagnosis or monitoring of many diseases.

Interpretation

Results outside of normal value ranges may reflect a primary disorder of the cell-producing organs or an underlying disease. Results should be interpreted in conjunction with the patient's clinical picture and appropriate additional testing performed.

Cautions

Questionable results are detected by in-house checking criteria based on quantitative and qualitative parameters.

 

Defined laboratory instrument or patient flagging criteria may trigger peripheral blood smear review resulting in consultant readout of hematologic abnormalities.
