Here is a message from Jennifer at the University of Tennessee at Memphis, who is doing a research study about utilization of the INR. Jennifer would like to document the frequency of PT tests ordered daily, nationwide. Please send a reply giving your laboratory’s volume so she can extrapolate to estimate a nationwide volume. Thank you.
Jennifer: thanks to Stephen Duff at Precision Biologic, we’ve located a CDC report on laboratory testing volumes. Click on http://wwwn.cdc.gov/mlp/coagulation_resources.aspx, it should bring you there.
