Specimen Requirements

Draw blood in a serum gel tube(s), preferred. Plasma from a lithium heparin is acceptable. 

Spin down within 2 hours of draw, and send 2 mL of serum (or plasma). Avoid hemolysis. If there is a delay in transport of >7 days, freeze specimen in plastic vial.

Unspun specimens must be transported at ambient temperature and arrive to the laboratory within one hour of draw.
