What does INR mean and why should patients trust this test resultWhile the Prothrombin Time (PT) test wasdeveloped in 1935, the INR value was developed in early 1980's. The need to standardize the PT test result so that coumadin dosing couldbe done with accuracy and confidence by health care providers was most important. Mostpatients on coumadin oral anti-coagulent therapy are familiar withthe terms PT or Prothrombin Time and INR but very few understand theconcept of why the INR is so important and critical to the dosing ofthis important plant derived medication.Prothrombin Time tests are performed inclinical laboratories all across the globe on sophisticatedlaboratory analyzers or in the point of care setting using a smalldevice the size of a tablet computer.The test was developed with the use ofpurified biological material made from the brain tissue of rabbits. As technology and manufacturing practices evolved, ProthrombinComplex reagent production was developed with recombinant manufacturingmethods without sacrificing the bunnies. Yeh! In early years before INR, the PTresult was expressed in several variations to give the physician abetter idea of the anti-coagulent effect of coumadin on his patient. The PT result was reported with a normal range which representednormal for the non-anticoagulated patient, other expressions of thePT result also combined a ratio value of test PT to Normal control, and also an established normal range ratio. However, dueto variances in the many different test methods, reagents available,and sometimes technique of the person performing the test, thepatients were at great risk of being over medicated or worse

Undermedicated and even worse still overdosed. Hence the INR value wasdeveloped to provide the physician with a stable and reliable testresult that was safe to use to dose patients with coumadin. Eventually, the WHO would get involved in the process of developingstandards used to this day for manufacturing reagents, assigning a numerical value to the reagents [talk about this later] and testprocedures.INR stands for International NormalizedRatio which is a test result reported from the mathematicalcalculation of three parameters; PT result, Geometric Mean of theNormal PT, and ISI value of the reagent used. Ok I know – notanother acronym!ISI stands for InternationalSensitivity Index. This is the crucial component that makes forreliable INR results for all patients no matter what lab or deviceperforms the PT test. The ISI value of every reagent manufacturedfor coagulation testing is assigned to that reagent based uponcomparison of performance characteristics set up by WHO ~ World Health Organization. The ISI ismuch like the Octane rating of gasoline. The octane rating is theproduct of a calculation provided to consumers to assure gasolinemeets certain performance standards. ISI is much the same thing. Reagents of different ISI values perform differently depending on theinstrument system and the coag status of the patient; meaningdeficiencies of coag factors, medications ingested, and testingconditions. Generally, the lower the ISI value of a reagent the moresensitive the reagent is to coag deficiencies which indirectlyreflects effects of coumadin therapy. The INR calculation is a brilliantmathematical process that helps to standardize a result used todirectly adjust dosing of

Cartridge • Time delays before filling cartridge, especially lactate, ACT, and PT/INR • Exposing the sample to air when measuring pH, PCO2 , and PO2 • Air bubbles trapped in the sample chamberHelpful Tips • Should the i-STAT System become inoperable for any reason or the result does not agree with the patient’s clinical condition, new specimens should be collected and submitted to the main laboratory and the POCC should be notified. • NEVER share your operator ID with others. Doing so will result in suspension of testing privileges and possible termination. • If the cartridge is overfilled (past the blue arrow) it may not seal properly. Do not wipe off the excess or draw it back into the syringe. You must obtain a new cartridge and start over. • Analysis times- • PT/INR cartridge: to detection of end point – up to 300 seconds (5 min.) • CG4 cartridge: 2-4 mins • Chem 8 cartridge-2-4 minsHelpful Tips, continued  • Remove the cartridge from the analyzer when the cartridge is unlocked. Do not removed until test is complete. • Some of the most common testing problems include: • Insufficient sample • Overfilled cartridge • Under-filled cartridge • Failure to adequately mix specimen before testing • Specimen clotted • Air bubbles trapped in the sample chamber • Pre-burst calibrant on the top of the cartridge • Touching the sensors on the cartridge • Sample lid not closed • A new sample should be drawn and a new cartridge used with
