Tests
An assay that measures the proliferative response of lymphocytes from one individual when they are exposed to inactivated lymphocytes from another individual. The reaction can be performed on lymphocytes from the same individual (auto-MLR), from different individuals of the same species (allo-MLR), or individuals from different species (xeno-MLR). It is used to evaluate the potential for graft-versus-host or host-versus-graft reactions during transplantation procedures involving mismatched tissue types or individuals.

Tests
A method for virus culture and detection in which a virus sample is mixed with a susceptible cell type and then centrifuged into a single layer of cells. Following a short incubation, viral growth is determined using immunological detection techniques.
For professionals
Tests
A two-staged test with purified coagulation factors in the first stage, and a FXa-specific chromogenic substrate in the second stage. In the first stage, diluted sample plasma, which has been treated with Al(OH)3 to remove prothrombin, is mixed with a combined reagent (human serum, factor V, phospholipids and calcium). In the second stage, a subsample from the first stage is mixed with normal plasma, providing prothrombin and fibrinogen, and the clotting time is measured to deduce the amount of FVIII present.
