Does anyone know if there is a limit to the amount of blood or # of vials that can be taken from a patient?? I work in home care and it is not uncommon to have several lab tests ordered, however, a pt i am seeing tomorrow has 13 labs ordered....i have never had that many to take from a single pt. I don't know how many different tests can be taken from a large vial as i am used to always using the small ones for cbcs, cmp, etc. Anyone have any advice? Thanks
No, there is no limit to the number of tubes drawn, though you want to limit them to just the essential ones. Especially is the pt is anemic or cannot easily be transfused.
As a research onco nurse, I have done 20-30 tubes (many research tubes are large - 10cc tubes) off a pt at a time.
Having said that, many the tests listed repeat themselves. The Hct and Hgb are part of the CBCD. And BS is part of the CMP, w/ Calcium off the same tube.
You need to contact the lab running them and find out what can be combined. Usually standard coags can be all run off one blue top, and CBCD/Hct/Hgb off one purple top. But some of the others may be send outs and require a separate tube.

I was a phleb before I was a nurse, and near as I can tell, it looks like 4-5 tubes. As for a limit, there's none that I know of. I've drawn as many as 27 on one patient when I was a phleb. Another phleb that I worked with at the time drew something like 32.

25 Hydroxy Vit D
The CBC w/diff includes the Hemoglobin and Hematacrit so that is 1 small lavender tube, draw a second small lavender tube for the BNP as 6cc is required for that test alone.
The Protime will be drawn in a small light blue tube
The CMP is drawn in a Red Tiger top tube so is the FBS, Calcium, PSA, 25 Hydroxy Vit D, B12, Folate, and PTH but you don't want to draw for more than 3 tests in each Red Tiger top tube so I would say draw:
2 small lavender tubes
1 small light blue tube
3 Red Tiger Top Tubes or 4 if the patient doesn't object. Sometimes the 25 Hydroxy Vit D is sent out and an extra Red Tiger Top tube is appreciated.

Another thought: You need to ask your agency for a policy about what goes in what tube. Many years ago my agency gave us this thick pocket size book with all the info in it. I kept it for years and even when I went to hospital Nursing I'd have it with me for my own reference.
We also had a color chart at the Nursing station that was sort of like this one:
