Quick Question: PTT Mixing Studies

The results of our January-February 2014 Quick Question:

Does your laboratory perform follow-up partial thromboplastin time (PTT) mixing studies 24/7?

a. No, only during the day shift, 46 (52%)
b. Yes, all day and all night, 30 (34%)
c. Not at all, we sent them out, 13, (14%)
Total votes: 89

Thanks for the response, most experts advocate for all local laboratories to provide a PTT mixing study as they are relatively simple and provide basic information on inhibitors versus coagulopathies before following up with profiles. Geo.
