Coagulation factor II circulating inhibitor [Presence] in Platelet poor plasma 50390-4
LOINC Code
| LOINC code | 50390-4 | ||
|---|---|---|---|
| name | Coagulation factor II circulating inhibitor [Presence] in Platelet poor plasma | ||
| description | PT circulating inhibitor is part of the PT mixing study. When addition of normal plasma fails to correct the clotting time into the normal range, the cause of the abnormal test is likely an inhibitor rather than a clotting factor deficiency. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Coagulation factor II circulating inhibitor | ||
| property | PrThr = Present or threshold: The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold. | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | PPP = Platelet poor plasma | ||
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||
| method | |||

| change reason | Changed Property from "ACnc" to "Pr" (Presence) to clarify that results (e.g. pos/neg, present/absent) are based on the presence of the inhibitor.; Changed Component from "Coagulation tissue factor induced circulating inhibitor" to "Coagulation factor II circulating inhibitor" to match the other factor inhibitor terms.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016. | ||
