Test Code 014 Hemogram (CBC no Differential)
Additional Codes
ALAB: HGM
PowerChart: Hemogram (CBC)
MA Cerner: Hemogram.
Test Method
Sysmex XN and XS Systems:
- WBC: Flow cytometry
- RBC: Impedance counting
- Platelet Count: Impedance counting
- Platelet F Count: Flow cytometry fluorescence count (performed when appropriate)
- HGB: Converted to SLS-hemoglobin and read photometrically.
- MCV: The average volume of individual erythrocytes derived from the RBC histogram.
- RDW: The size distribution spread of the erythrocytes population derived from the RBC histogram.
- MPV: The average volume of individual platelets derived from the PLT histogram.
- HCT: Measured as a ratio of the total RBC volume to whole blood using cumulative pulse height detection.
- MCH, MCHC: Calculated parameters.
MCH: Weight of HGB in the average RBC. MCH = HGB ÷ RBC x 10
MCHC: Average weight of HGB in a measured dilution. MCHC = HGB ÷ HCT x 100
Specimen Requirement
EDTA whole blood is required.
Additional Specimen Collection Information
Whole blood collected in EDTA purple-top tube. The tube must be at least one quarter full to be acceptable for testing.
Capillary specimen collected in EDTA microtube. The tube must contain at least 375 mcl (bottom line) to be acceptable for testing.
Performance
Testing is performed Monday through Sunday.
Routine orders: Typically completed within 4 hours after the specimen arrives at the testing site.
Expedite orders: Typically completed within 1 hour after the specimen arrives at the testing site.
STAT orders: Typically completed within 30 minutes after the specimen arrives at the testing site.
