LOINC code75506-6
nameaPTT.lupus sensitive W excess phospholipid (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 platelets or hexagonal phospholipids and think it important to distinguish their source can use 3284-7 or 3282-1, respectively, instead of this term.

componentCoagulation
propertyTime  =  Time Duration
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.surface induced.lupus sensitive with excess phospholipid
