WebAug 3, 2024 · Reference Range. Factor V is a large glycoprotein with a molecular weight of 330,000 daltons and a plasma half-life of about 12 hours, with some reports of a half-life of up to 36 hours. [ 1] It functions as a cofactor in converting factor II to active factor II. It is proteolyzed by protein C/S complex. [ 2] The reference range for factor V is ... Webovercome by dilution into factor V-deficient plasma. The role of factor Xa is replaced by Noscarin, a factor Va-dependent but phospholipid-independent prothrombin activator derived from the Tiger snake Note-chis scutatus. Phospholipid and calcium are not present in the reagent. Phospholipid independence should eliminate interference by lupus anti-
