Heparin and PTT


Specializes in Starting dialysis.

I am working on a practice test and need help figuring out the following:

The hospitals control for PTT is 35 seconds. What is the therapeutic level?

I thought I was supposed to multiply the 35 by 1.5 and 2.0.


I'm 99% sure that is correct. That's what I learned in class, anyway.

I just found out that I was entering it in the computer wrong but my answers were correct. Thanks for answering!
