Notify laboratory prior to collection. Transport to lab immediately after collection.

Test Code

Preferred Specimen
Light blue top tube

Minimum Volume
Tube should be filled within 10% of expected draw volume. BD Vacutainer tubes have a minimum volume line molded on the tube. The sample is unacceptable when the meniscus of the blood is below the molded line.

Avoid collecting from IV lines or arterial lines, as they may become contaminated. If unavoidable, the IV must be turned off at least 2 minutes and a minimum of 5 mL of blood drawn as a discard prior to collection. Central lines containing heparin must be flushed with 5 mL of saline and then 5 mL of blood must be discarded. If applicable, indicate sample type on the label (baseline, on pump, etc.).

Transport Temperature
Room temperature only

Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
Inadequate volume, clotted, gross hemolysis, refrigerated, centrifuged, received in lab greater than 2 hours after collection
