A message from Sue Allen at Baptist Hospital: George, a while back you posted aquestion to the masses about the correlation between the Abbott i-STAT ACT versus the ITC Hemochron 401 and the Hemochron Jr. and I was wondering if you ever received any responses and have any further information on the subject. We are currently doing the same conversion and needless to say, the methods do not directly correlate. They do quite well at the lower ranges but at the 300–350 sec levels they seem to differ by as much as 100 seconds.Thank you in advance for any light you can shed on the subject.
Hello, Sue, and thank you for your question. I don’t have a lot of light to shed on the subject, though I know that the longer ranges of the ACT are important to anesthetists in cardiac surgery for monitoring heparin. If anyone has something to contribute, please add your comment below.
