Coagulation factor VIII inhibitor [Units/volume] in Platelet poor plasma by Chromogenic method   93450-5

LOINC Code


LOINC code93450-5
nameCoagulation factor VIII inhibitor [Units/volume] in Platelet poor plasma by Chromogenic method
descriptionThis term is created for but not restricted in use to a Nijmegen modification of the classic Bethesda inhibitor titration assay using a chromogenic method. The use of a chromogenic method allows factor VIII inhibitor to be detected in patients receiving emicizumab / Hemlibra®, a therapeutic that interferes with standard clot-based methods [PMID:29446525].

Fully-Specified Name

componentCoagulation factor VIII Inhibitor
propertyACnc  =  Arbitrary Concentration
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemPPP  =  Platelet poor plasma
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
methodChromo  =  Chromogenic/Enzymatic Assay:  To distinguish coagulation assays based on chromogenic (enzymatic) activity.
