WebThe classic laboratory findings in APLS patients are prolonged aPTT, normal PT, and no correction of the aPTT 1:1 mixing study. Adding excess phospholipid to the aPTT assay, however, reduces the clotting time. This is the basis for the so-called LA assay. One version of the LA assay is the dilute Russell's viper venom time (dRVVT).
