Kit recommendations for PT-INR local ISI calibrations?

[TMaxwell]

Hello everyone. First post here and I was wondering if anyone here can recommend a certified plasma kit to perform a local ISI calibration to confirm their PT-INR testing setup matches package insert values? The lab I work at is a bit odd in that we use one companies PT-INR reagent with another companies coagulation instruments.

Thank you in advance for any leads or suggestions.

It's a bit late this, but my lab uses AK Calibrant with a Stago analyser and reagents for ISI calibration.
