Performing Laboratory
UnityPoint Finley Hospital
Test Method
Sysmex XN:
- 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
Performance
Testing is performed Monday through Sunday.
Routine orders: Typically completed within 2 hours upon receipt in the lab.
STAT orders: Typically completed within 30 minutes upon receipt in the lab.
Specimen Requirement
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.
Useful For
Screening tool to confirm a hematologic disorder.
Establish or rule out a diagnosis.
Detect an unsuspected hematologic disorder.
Monitor effects of radiation or chemotherapy.
These counts are used as clinical guides in the diagnosis and/or monitoring of many diseases.
