A note from Beth Lewis:
I’ve just signed onto your site and so far am very impressed with its content. I’ll know I’ll refer to it regularly. Thanks so much for setting it up.
I have a question for which I’ve been unable to find a good answer: When performing a manual test for PTT, due to an error code on our analyzer, if a wispy clot is detected at some point during the testing but does not reach a solid clot by 120 seconds, what would be the best way to report this?
Hi, Beth, thanks for joining and thank you for your question. I’ll put this out there for people to respond, however my approach would be to report greater than 120 seconds (or whatever limit seems appropriate) and append a note describing the clot. It might also be interesting to see how an optical analyzer such as Beckman-Coulter equipment would respond, as these instruments provide a “clot curve.” Geo.
