For those of you already using the hs-TnI cartridge on iSTAT, are you running whole blood or plasma? If whole blood, what is your process for patients with a HCT >55%? Our thought was to add a disclaimer to all results but we're not sure that's the best option since so many people overlook a disclaimer and it's rather important to know if you need to repeat this test. We have a fairly high volume so checking every patient's HCT is not feasible and running ALL tests on plasma won't sit well with the ED docs since that would be adding an additional 3-5 minutes to an already longer turnaround time.
Any and all suggestions or information is appreciated.

We don't run troponin on the iSTAT but I would recommend following the IFU. I would definitely think that the ED Providers would rather an accurate result 3-5 later than an inaccurate result 3-5 minutes sooner. Your IT department might be able to help with linking a HCT to the hs-TnI for this check to be done easily prior to analysis depending on your LIS. Utilize your Pathologist as needed for leverage.
