I have to draw a PT/INR and want to know if it needs to be done at a certain time of day or if there any other special things I need to know...have never done one before. I will be doing the stick, there's no line in place, will be done in the home.
I did a search on the board but if there's something here on it, I didn't see it...
Ditto what previous poster said about having the blue top tube filled to the label. Otherwise the nice folks at the lab will hand you the tube back and tell you to redraw. I used to use a expired tube to start the draw and THEN pop my blue top on there.
I always tried to draw Pt/INRs in the morning and called them in to MD right away so I had half a chance of hearing back by the end of day. Good luck.

: Reason: spelling
I have done it 2 ways
One: with the INR machine, like a glucometer but you need a nice fat dollop of blood otherwise you waste the strip, make sure you get it right on the target!
Two: blood in a specimen tube, I find it easier to butterfly into a 3 ml syringe then stick the specimen tube!
Timing wise, it doesn't matter, it depends on the client! You have to draw it early enough to send results and get the physician's response on the same day! Some times with home health we get it all set and the physician takes forever to respond..... But by having it drawn and read you can know if it is critical or not!
