Method and apparatus for coagulation based assays |
摘要 |
An activated partial thromboplastin time (APTT) test is described which employs fresh, whole blood that has not been anticoagulated. The method employs a disposable cuvette having specific reagents placed therein. A sample of whole blood is introduced into the cuvette which is drawn into at least one conduit by a pneumatic pump. Initially, the calcium in the sample is chelated at a first reaction site in the conduit, and thereafter is moved through the conduit to a second reaction site where the sample is coagulated by an APTT reagent. After a predetermined incubation time, the sample is moved to a third reaction site where it is recalcified. Clotting time is measured from the time that the sample is recalcified to the time that clot formation is visibly detected.
