• Positive HCV-antibody test with negative HCV RNA by polymerase chain reaction (PCR): Inform patients they do not have evidence of current (active) HCV infection. (medscape.com)
  • Reinfection after previous spontaneous or treatment-related viral clearance: Obtain initial HCV-RNA testing (because an HCV-antibody test is expected to be positive). (medscape.com)
  • A rapid antibody test for HCV is available. (medscape.com)
  • The first is the test for cardiolipin or beta2 glycoprotein I antibodies. (labtestsonline.org.uk)
  • But that was usually it unless there was something in the history or physical exam that would lead me to look for something less common - for example, cryoglobulins or an underlying hematologic disease that would lead to a predominance of lesions in acral sites. (the-hospitalist.org)
  • They underwent clinical assessment and blood testing for factor V Leiden, prothrombin G20210A, methyltetrahydrofolate reductase C677T, plasminogen activator inhibitor type 1 (PAI-1) mutations, antithrombin, proteins C and S levels, and also antiphospholipid antibodies (anticardiolipin antibodies and lupus anticoagulant), cryoglobulins and cryoagglutinins.

  • [ 12 ] Laboratory abnormalities include elevated anticardiolipin antibodies, sedimentation rate, blood pressure, and creatinine as well as a mild leukocytosis and eosinophilia. (medscape.com)
  • The prevalences of factor V Leiden, prothrombin G20210A, elevated titer of antiphospholipid antibodies and the presence of cryoglobulins were higher in the early onset group, although the differences were not statistically significant. (nih.gov)
