Test ID: ALUPP    
Lupus Anticoagulant Profile, Plasma

Useful For Suggests clinical disorders or settings where the test may be helpful

Confirming or excluding the presence of lupus anticoagulant (LAC), distinguishing LAC from specific coagulation factor inhibitors and nonspecific inhibitors

 

Investigating a prolonged activated thromboplastin time, especially when combined with other coagulation studies

 

This test is not useful for the detection of antiphospholipid antibodies that do not affect coagulation tests. We recommend separate testing for serum phospholipid (cardiolipin) antibodies

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

Initial testing includes: prothrombin time (PT), activated partial thromboplastin time (APTT), and dilute Russell viper venom time (DRVVT).

 

If the PT, APTT, and DRVVT are normal, a computer-generated interpretive comment indicating no evidence of a lupus anticoagulant will be provided.

 

If PT is >13.9 seconds, PT mix will be performed at an additional charge.

 

If APTT is > or =38 seconds, APTT mix will be performed at an additional charge.

 

If PT, APTT, or DRVVT are prolonged, thrombin time (TT) will be performed at an additional charge.

 

If APTT mix is > or =38 seconds and thrombin time is <35.0 seconds (no evidence of heparin), platelet neutralization procedure will be performed at an additional charge.

 

If DRVVT ratio is > or =1.20, DRVVT mix and DRVVT confirmation will be performed at an additional charge.

 

If TT is > or =25.0 seconds, reptilase will be performed at an additional charge.

 

If appropriate, coagulation factor assays, fibrinogen, D-dimer, Staclot LA, and soluble fibrin monomer will be performed to clarify a significant abnormality in the screen test results at an additional charge.

 

If factor VIII result is <55%, the factor VIII inhibitor screen may be performed along with the Bethesda titering assay, if indicated at an additional charge.

 

If any test results are abnormal, all results will be reviewed by a coagulation consultant and a Lupus Anticoagulant Interpretation will be provided.
