Non-Criteria Antiphospholipid Syndrome (APS) (aPs, aPt, aPs/aPt) Antibodies Panel
Also known as: NCAPS PAN
Use
This test is used for risk estimation of antiphospholipid syndrome (APS) when criteria antiphospholipid tests return negative or equivocal results. APS is an autoimmune disorder associated with recurrent thrombosis and pregnancy complications. The presence of antibodies against phosphatidylserine and prothrombin is evaluated to provide information on the risk of developing venous or arterial thrombosis.
Special Instructions
Not provided.
Limitations
Results from this test should not be used as a standalone diagnostic tool. They must be interpreted in conjunction with clinical findings and other criteria phospholipid antibody tests, as the isolated presence of antibodies may have questionable clinical significance. Positive results should be further confirmed with repeated testing using specimens collected at least 12 weeks apart to establish antibody persistence.
