Specimen Requirements
Collection

Liquid EDTA K3 collection tubes are not acceptable and will be rejected due to possible dilutional effects.

Collection Instructions

Collect specimen in a lavender top EDTA K2 Vacutainer® tube or EDTA K2 Microtainer® tube. Send intact within 8 hours of collection if stored at room temperature or if stored refrigerated. Two unstained peripheral smears made from the specimen at the time of collection may be submitted concurrently if transport cannot be done within 8 hours. Then the specimen must be received within 24 hours kept at room temperature, or 48 hours if refrigerated. The request for Pathologist Review must be accompanied by a reason for review. If no reason is provided, a peripheral blood smear will be prepared and will be available in the Hematology Laboratory for 30 days. Please contact MLabs within 30 days.NOTE: Blood smear preparation cannot be done on specimen more than 8 hours old due to increased cellular degeneration. This may result in the differential and pathologist review request being canceled.

Rejection Criteria
Specimens clotted, diluted with IV fluid, containing fibrin strands and clumped platelets, or in underfilled or improper tubes will be rejected.
