Specimen Type
Urine
Requested Volume
2 mL
Minimum Volume
0.8 mL
Special Handling
Patient Preparation: If possible, the patient should abstain from medications for 72 hours prior to collection.
Specimen Preparation: Transfer a 4 mL aliquot from a random collection to a Standard Transport Tube (Min: 0.5 mL). Stability can be enhanced by adjusting the pH to 2-3 by using an acid such as 6N HCl. Urine without preservative is acceptable if pH is below 6 and the sample is shipped frozen. Record collection time on transport tube and test request form. Do not use Boric Acid.
Specimen Container
