USP <797> details EM procedures required for compounding pharmacies. Most state Boards of Pharmacy will audit 503a Compounding Pharmacies to these standards.

- Sampling frequency
USP <797> criteria is to sample at least twice a year. Given seasonal fluctuations, inevitable fluctuations in activity, process and equipment changes – twice a year is inadequate and the USP committee will change this in the near future.
In the meanwhile, consider sampling more frequently to get a true value of your facility's microflora. FOCUS can help develop a rational sampling plan, and train your staff to take samples properly.
- Microbial Identification
FOCUS Laboratories characterizes every colony into groups, based on Phenotypic colonial morphology. Further identification to species level is possible via biochemical or genetic characterization. CLICK HERE for more on Microbial Identification.
USP <797> indicates that corrective actions be dictated by the identification of microorganisms recovered (at least the genus level) by an appropriate credentialed laboratory (FOCUS Laboratories). Highly pathogenic microorganisms (Gram-negiatve rods, coagulase positive staphylococcus, mold and yeast) can be potentially fatal to patients receiving CSP and should be immediately remedied regardless of count.
