Urinalysis w/ reflex microscopic-399
UA w/ sediment exam reflexed per criteria
Specific gravity, pH, protein, glucose, ketones, bilirubin, blood, urobilinogen, nitrite and leukocyte esterase.
If any of the following criteria are met, a microscopic exam will be reflexed:
| Color | Any color other than Yellow |
| Clarity | ≥ Slightly Cloudy |
| Blood | ≥ Trace |
| Protein | ≥ 1+ |
| Nitrite | Positive |
| Leukocyte esterase | Positive |
| Glucose | ≥ 1000mg/dL |
| Bilirubin | Abnormal |
Refrigerated specimens in screw cap container received >8 hrs but <24 hrs from collection will be resulted with a comment: "Specimen exceeds standard time for testing"
Colllect a freshly voided urine; midstream clean-catch or catheterized
Transfer specimen to a BD Urinalysis Preservative Tube. The tube has a minimum fill of 7-10 mL; 10 mL is preferred.
Urine processing instructions (BD)
Screw cap plastic container (non sterile or sterile)
If a BD UA transport tube in not available, or there is insufficient specimen, transport the entire specimen in the collection container.
BD Urinalysis preservative tube (preferred):
Ambient - 72 hours
Screw cap plastic container:
Refrigerated - 8 hours
- Improper labeling (unlabeled or mislabeled)
- Delay in transport
- Leaking container compromising the specimen
- Improper storage/transport temperature
- Interfering substances
