The sensitivity of different coagulation reagents to the presence of lupus anticoagulants

Douglas A. Triplett·1986·Thrombosis Research

Abstract

The sensitivity and responsiveness of seven activated partial thromboplastin time reagents to the presence of lupus anticoagulants (LAs) was evaluated with a panel of 50 well-characterized LA plasmas. The results document that some reagents are clearly less responsive and sensitive to LAs; however, there is considerable variability between individual LA samples in these features. In addition, with 16% of these samples, immediate mixing studies showed correction of the activated partial thromboplastin time to the normal range with a 1:1 mixture of normal and LA plasma and 8% to 10% showed either a normal platelet neutralization procedure or a normal tissue thromboplastin inhibition procedure. Together, these findings provide further evidence of the laboratory heterogeneity of these inhibitors. The effect of this variability on the diagnosis of these inhibitors is discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
