ACT using Response RxDx System

Here is a question from new member Patricia Doleski:

I oversee the activated clotting time (ACT) program at two hospitals that use the Response RxDx System. One has no problem reaching the calculated heparin target (480s). They are using 5,000-unit heparin preparations.
The second hospital is having a problem using the RxDx calculation on certain patients. They are using 1,000-unit heparin. I know we anticipate 10% expected variability in the strength of heparin from what is labeled. Is there an “industry standard” strength of heparin used for cardiac surgery or perfusion?

Patricia, thank you for your question. I’ll put this up for our pathologist or cardiac surgeon participants to answer. Geo
