Liquid EDTA K3 collection tubes are not acceptable and will be rejected due to possible dilutional effects.
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, in which case the specimen must be received within 24 hours kept at room temperature, or 48 hours if refrigerated. NOTE: Blood smear preparation cannot be done on specimen more than 8 hours old due to increased cellular degeneration. This may result in the Red Blood Cell Morphology being canceled.
If a Complete Blood Count (CBC) or Complete Blood Count with Differential (CBCD) has not been requested, a CBC will be added at an additional charge. Test may include pathologist interpretation of results at an additional charge. By ordering this test, the clinician acknowledges that a pathologist interpretation will be performed and billed as a separate additional charge if indicated.
