| Directions | If analysis cannot be performed promptly (<30 min), the urine should be stored refrigerated to maximize cell preservation and minimize bacterial growth, but analysis should still be performed within 12 hours. After this time, cells will begin to lyse (usually by 24 hours, unless the urine contains a substantial amount of protein, which helps preserve cells), because urine is a “toxic” environment, and bacteria will proliferate. We do not recommend adding any preservatives, e.g. formaldehyde, toluene, to the sample because they all introduce artifacts in results (which vary, depending on the preservative). Before analysis, samples should be brought to room temperature. Note that artifacts are still seen with storage. Calcium oxalate and magnesium ammonium phosphate crystals all may develop over time with storage (i.e. were not present in a freshly examined sample). |
