| antithrombin, antithrombin III, AT, AT III, and heparin cofactor activity apply to the same assay. If you cannot find the assay you need, please contact us for assistance. Each entry provides specimen management instructions, CPT codes, turn-around times, reference intervals, clinical interpretations, and recommendations for further testing. Recommendations are an aid to, and not a replacement for, clinical judgment. |

| Click here for detailed instructions on coagulation blood specimen management. The names of several coagulation tests are confusing. Please click below for the "confusing coagulation test names" page. Is it the factor V Leiden mutation or the factor V activity assay? Is it the anti-Xa test for heparin or the factor X activity assay? Is it the protein C activity assay or the C-reactive protein test? Is it the von Willebrand disease profile or the von Willebrand factor cleaving protease assay? |

| Prior to performing the genetic test for the factor V Leiden mutation, the activated protein C resistance (APCR) assay should be performed as a screening test. The factor V Leiden mutation test is performed when the APCR is positive. |
