Geisinger Epic Procedure Code:  LAB2734    Geisinger Epic ID:  6857

SPECIMEN COLLECTION
Specimen type: 

Urine


Preferred collection container: 
Specimen required: 

4 mL of a random urine collection submitted in a Myoglobin Transport Tube within 1 hour of collection. For collections outside of GMC or GWV you must make arrangements to either have a Myoglobin Transport Tube on hand or deliver the urine specimen to Referred Tests within one hour of collection.


Special notes: 

Add exactly 4 mL random urine to a Myoglobin Transport tube, within 1 hour of collection. Freeze and ship frozen. Exactly 4 mL of urine in the Myoglobin Transport tube is required to achieve the required pH of >8.0; more than 4 mL of urine will lower the pH outside acceptable range.
