Critical values/courtesy alerts:
 See individual member listings
Additional information:
 Patient with clumped platelets will result an estimate only (decreased, adequate, increased). For EDTA platelet clumping, order Platelet Count for Patients with Platelet clumping (LAB2859), an additional blue-top (sodium citrate) tube is required.

Potential related available add on testing includes: reticulocyte panel (LAB3006); immature platelet fraction (LAB2524) can only be added if sample is collected at testing laboratory; blood smear interpretation by pathologist (LAB2832).

See individual test requirements.
CPT code(s):
 Varies with differential methodology
Note: The billing party has sole responsibility for CPT coding.  Any questions regarding coding should be directed to the payer being billed.  The CPT codes provided by GML are based on AMA guidelines and are for informational purposes only.
Test includes:
 WBC, RBC, HGB, HCT, MCV, MCH, MCHC, RDW, PLT, MPV and WBC differential with absolute values and percentages. The CBC analyzer will flag certain abnormalities for manual review. A technologist performed WBC differential and/or morphology scan may be automatically performed. Technologist may identify abnormalities that require additional pathologist review.
Methodology:
Electronic resistance detection enhanced by hydrodynamic focusing and flow cytometry
Microscopic Examination
Synonyms:
CBCD
CBC/Diff
Blood Cell Count with Diff
Clinical significance:
Complete blood count plus white blood cell differential which looks at the types of white blood cells present to aid physician in diagnosing infection, viral condition or other disease affecting the white blood cells, such as leukemias. The white blood cell differential assesses the body's ability to respond to and eliminate infection. It also detects the severity of allergic and drug reactions, plus the response to viral, parasitic, and other types of infection. It is essential in identifying various stages of leukemia and monitoring response to chemotherapy.
