Yes, a retest is mandatory anytime your reaults are not WNL. The test is to be done the same day. I did reuse for several years, and was resposible for all the LALs and other waterchecks. If you ARE getting high counts of bacteria, I would cetainly let somebody in the Tech dept. know.. often the nurses don't deal with this end of it. Although the DON should be fully aware of ALL aspects of even the water testing, etc. We nurses have to go through annual inservices on all the water system as well. But I'd be calling the chief tech if I were you (after your retest) if it's still elevated. I wouldn't wait 'til the patients START showing symptoms... get it looked into ASAP if your count is still high. If the machine dialysate LALs are high, too, you've got trouble there. Protect your patients... then CYA and make sure someone up the ladder is informed.
Babs.. we (nurses) all have to do the waterchecks where I work along with the techs (we only have one).. we all take turns.. a different person each day. So yes, we do the culture paddles, LALs, the whole bit. Really kinds sux, considreing all the other NURSING responsibilies we have as well.
