i-STAT PT/INR is a lab-quality, moderately complex test intended for the monitoring of patients receiving oral anticoagulation therapy such as Coumadin or warfarin. I hope the release of this preliminary data will prompt other clinical laboratories to review their results. Providing lab-quality results fast when every minute counts. I have decided to discontinue bedside INR testing with ISTAT until this discrepancy has been resolved. Blood samples were analyzed first by the Radiometer ABL to complete physician-ordered laboratory tests and then by the i-STAT cartridges. This small single study suggests that clinicians cannot make accurate clinical decisions based on I-STAT INR results.
accuracy and compared favorably with the I-STAT and ABL 835 Radiometer assay results. ISTAT INR was as much as 0.5 lower than STAR when the STAT INR is 2.8 I-STAT (Abbott Point of Care) is a popular device for point of care testing that is used in hospitals to provide quicker turnaround time and expedite. Portable, wireless blood gas analyzer with 11 critical tests for.Therefore, the location at which a laboratory test is performed does not classify it one way or the other. This study demonstrated significant INR differences between I-STAT and STAR. These results were much more discrepant than the results published in the I-STAT Prothrombin Time/PT packgage insert that compared I-STAT to STA Compact. Even more disconcerting was that the bias was inconsistent throughout the therapeutic range. For regulatory purposes, satellite laboratories are generally considered extensions of the central laboratory service, rather than a separate classification such as POCT. Recently, I compared the INR results of patients treated with warfarin who were simultaneously tested with a fingerstick specimen on an I-STAT at the bedside and a venipuncture specimen on a Stago STAR coagulation analyzer located in the main clinical laboratory.

I-STAT INR cartridges are used to determine if a patient presenting to the ED with an ischemic stroke can receive tissue plasminogen activator or if a patient anticoagulated with warfarin can undergo an emergent invasive procedure.
