test app

 
TEST NAME: COMPLETE BLOOD COUNT (CBC) WITH AUTO DIFFERENTIAL
Includes: WBC, RBC, hemoglobin, hematocrit, platelet, RBC indices, and WBC differential
Testing algorithm: If platelet count is <50 K/cumm then an IPF will be performed at an additional charge.
LAB DEPT: Core Lab
 
SPECIMEN REQUIREMENTS
Specimen Type:
Whole blood
Container/Tube
 
Preferred:
Lavender-top (EDTA) Vacutainer®.
 
Acceptable:
Lavender-top (EDTA) Microtainer®.
 
Collection Volume:
Vacutainer®: 2.0 mL (minimum 0.5 mL)
Microtainer®: minimum 0.3 mL
 
Patient Preparation:
None
 
Sample Rejection
Clotted specimens.
Mislabeled or unlabeled specimens.
 
Special Instructions:
Immediately invert tube/microtainer® gently 8-10 times after collection to ensure proper mixing of blood and anticoagulant (this will avoid specimen clotting). Do not overfill tube.
