Do I have to flush before withdrawing a blood from a PICC even a 0.9 Nacl + k running - page 2

Yes ..I agree on the volume...2 x the priming volume of the line is adequate as I stated. I was addressing all types of CVCs for the most part since a blood draw will be similar for all with some slight variations. Checking into the vacutainer issue as well since I think you can use it under certain circumstances,,will post when I am done checking my resources. Some hospitals will state a specific volume in their policies to cover all types of CVCs.
