Performing Laboratory
TidalHealth Peninsula Regional - Core Laboratory: Hematology
Specimen Requirements
Submit only 1 of the following specimens:
Capillary
Specimen must arrive in laboratory immediately after collection.
Collect blood in a lavender-top (EDTA) MICROTAINER, and send 0.5 mL of EDTA whole blood. (Clotted or hemolyzed specimen is not acceptable.)
Note: 1. Indicate capillary blood.
2. Label specimen appropriately (capillary blood).
Venous
Specimen must arrive within 24 hours of draw.
Draw blood in a lavender-top (EDTA) tube, and send 4 mL of EDTA whole blood. (Clotted or hemolyzed specimen is not acceptable.)
