If any of you guys out there need to do your own, this is how I do it when needed....I have been on TRT for 4 years, my H&H stays high normal....I have only had to do 2 phlebotomies....if you have access to a IV set, I establish a 18g IV in my arm, set up a liter of Normal Saline, with a tube set that has a extension built into it, I hook the extension set up to a bag of 250cc saline that I empty before hand, I drop that to the floor & fill with blood, close clamps, then run the saline in. To replace the lost fluids. Good to go & no mess. You can't run blood backwards thru a drip chamber so you need a straight tube set or. Blood set, or a extension set....I just grab a piggyback line because it is without a drip chamber. I couldn't find a blood set this last time so I figured out the above. 250cc = 1 pint. You can order all this stuff from bound tree medical if you don't have access, but then you need someone who can establish a IV
