mixing study

A test to determine the cause of an elevated prothrombin time, thrombin time, or activated thromboplastin time. The patient's blood is mixed with normal blood. If the abnormal test result is corrected, the patient has a deficiency of a clotting factor. If it is not, an antibody or inhibitor to a clotting factor is present in the patient's serum.

(22) However, antibodies to factor X, although exceedingly rare, may produce a similar profile, and some of the newly developed oral direct factor Xa inhibitor medications will prolong the PT and aPTT but not the TT and will show an inhibitor pattern in a mixing study. (23)
Thrombin time 1:1 mixing study: This test is used in diagnosing acquired dysfibrinogenemia due to antibodies to fibrinogen in patients with immunologic disorders.
A mixing study was ordered confirming the presence of an inhibitor.
We performed a 1:1 mixing study for the prolonged APTTs using normal pooled rabbit plasma and the prolonged APTT corrected from a mean elevated time of 100.3 seconds using a LA-sensitive APTT reagent called PTT LS reagent to 58.9 seconds mean time in the 10.0[micro]pg group.
One of his most outstanding technical achievements at PPI was to lead the industry-sponsored Polymer Mixing Study. Nineteen of the world's leading plastics manufacturers supported and participated in this study, which dealt with the experimental and computational aspects of laminar dispersive mixing in immiscible compatibilized and reactive polymer blends, and with the study of melting of single-component and multicomponent polymer systems by the mechanism of plastic energy dissipation.
And the prospect of leaving university with an average debt currently of pounds 13,500, means more students are mixing study with work, leaving less time to spend in union bars.
The idea of mixing study and pleasure comes from the University of Glasgow's own Dr Laughter - Dr Lawrence Grove.
