We've always set up 0.5 mls on a blood agar plate and incubated for 48 hrs.
We used a colony count of <200 for H20 and <2000 for dial fluid. We would
only identify organisms if there was a single colony type greater than the
acceptable limits. Even if the cc was high but still acceptable the dialysis
people would bleach out the machines - or what ever they needed to do. A
repeat culture a day or 2 later would almost always be CC <2/ml.
