whats the smallest gauge needle used for CBC?
- 0May 5, '06 by hotdog19dCould you use a 25 gauge needle for a CBC draw? I would think it would be to small and damage some of the red blood cells, making the CBC inaccurate.

We either use butterflies for our lab draws (21, 23, or 25 gauge) or vacutainer needles (21 or 22gauge).
