  • Prothrombin Antibody (IgG)

Specimen Collection

Special Instructions

See Link and Print "Drug List for Special Coagualtion Tests"

Preferred Specimen

1 SST (speckled top) or 2 GST (gold top) tube(s)

Minimum Volume

2 Frozen Capped aliquots of at least 0.5 mL serum (Polypropylene tubes recommended)

Instructions

Use standard venipuncture and disposal techniques.

SST/GST tube: Avoid hemolysis.
1. Invert a minimum of 5 times, and then allow clotting in an upright position for 30 minutes.
2. Centrifuge the SST/GST for at 3000 rpm for 10 minutes.
3. Spun SST/GST tube remains at refrigerated temperature (2-8 degrees C) for transport up to 72 hours.
4. Serum must be removed from original SST/GST tube and frozen at <-20 degrees C in plastic polypropylene aliquot tubes within 72 hours of collection. Refer to the Minimum Volume section above for the number of aliquots required per test.
