Beta 2 GP1 IgA
Order Code:
BETA2A
Test Summary
Anti-phospholipid antibodies are a heterogeneous group of immunoglobulins that bind to several anionic phospholipids, including cardiolipin and phosphatidylserine. High serum levels of anti-phospholipid antibodies are frequently detected in patients with autoimmune (e.g., SLE) and non-autoimmune diseases, as well as in apparently healthy individuals. These antibodies have been associated with an increased risk for recurrent arterial and venous thrombotic events, thrombocytopenia, and fetal loss. These manifestations are the main features of the anti-phospholipid syndrome (APS).

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.
