METHOD FOR MEASURING CLOTTING TIME, METHOD FOR DETERMINING PRESENCE OR ABSENCE OF LUPUS ANTICOAGULANT, AND REAGENT KIT FOR DETECTING LUPUS ANTICOAGULANT

摘要

Disclosed is a method for measuring clotting time including: preparing a measurement sample by mixing a blood specimen suspected to contain a lupus anticoagulant, an activator, and a divalent-metal-ion-producing compound for facilitating formation of a phospholipid-containing complex; and measuring a clotting time after adding, to the measurement sample, an aqueous solution of a calcium salt as a coagulation initiator.
