Chemistry Specimen Requirements
| | Type | - Random Urine (specify clean catch, midstream, or catheter)
| | Container | - Preferred Collection Container: Graduated conical bottom tube with cap
- Alternative Collection Container: Graduated conical bottom tube without preservative or Sterile container (Starplex or similar container)
| | Required Volume | - Optimal Volume: 8 mL
- Minimum Volume: 3 mL
(Submitting
the minimum volume makes it impossible to repeat the test or perform
confirmatory/reflex testing. In some situations, a minimum volume may
require a second collection.) Pediatric Volume: 1 mL
| | Stability/ Storage | - 48 hours at 25°C with preservative
- 4 hours at 2 - 25°C without preservative
| | Grounds for Rejection | - Specimens received where the proper collection protocols were not followed
- Specimens received more than 4 hours after collection without preservative
- Less than 7 mL with preservative tube
- Grossly bloody specimens
- Unusually colored specimens (i.e.. blue-green): urinalysis will be cancelled and microscopic ordered
