whats the smallest gauge needle used for CBC?

  1. 0 Could 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.

    boy! are the phlebotomy gods with you today! i happened to run across a really nice website yesterday explaining how to do phlebotomy. i'm sure your question is answered in there because i remember seeing something in there about hemolysis which would be a concern when using a small gauge needle to draw blood. there is a slide show of photographs on how to draw blood and do a fingerstick (the lab version, not for doing a blood glucose) to link into at the site. here is the link. read on!

    Thanks, Daytonite, for a truly awesome resource.

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