Quantitative Electrochemiluminescent Immunoassay
Within 24 hours
Fine needle aspiration in saline. Also acceptable: Specimens collected in Green (Sodium or Lithium Heparin) or Lavender (EDTA).
Specimen must be non-viscous, non-hemolyzed, and free of particulate matter. Centrifuge to remove cellular material and visible hemolysis. Transfer 0.5 mL saline needle rinse to an ARUP Standard Transport Tube. (Min: 0.5 mL)
Specimen types other than those listed. Specimens too viscous to be aspirated by the instrument. Grossly hemolyzed samples. Grossly lipemic samples.
Indicate source on test request form.
Ambient: 8 hours; Refrigerated: 24 hours; Frozen: 6 months
