LOINC code75508-2
nameaPTT.lupus sensitive W excess phospholipid actual/Normal (normalized LA confirm)
descriptionIf the coagulation defect corrects with excess phospholipid, it confirms the likely presence of phospholipid antibodies and the LA syndrome. Platelets, bilayer and hexagonal phospholipids are variously used as the source of excess phospholipids and this term covers them all. The use of one term for these variations reduces mapping work for practices that import laboratory results, but laboratories that use hexagonal phospholipids and think it important to distinguish their source can use 75914-2 instead of this term.
statusACTIVE

Fully-Specified Name

componentCoagulation surface induced.lupus sensitive.excess phospholipid actual/Normal
propertyRelTime  =  Relative Time
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
methodCoag  =  Coagulation Assay:  To distinguish coagulation assays based on clotting methods that test function/activity from Immune methods that detect the presence of clotting factors and may or may not be functional assays.
