Test Catalog

Test ID: MYGLU    
Myoglobin, Urine

Specimen Type Describes the specimen type validated for testing


Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing

Supplies: Urine Myoglobin Transport Tube (T691)

Container/Tube: Plastic, 10-mL urine myoglobin transport tube (T691)

Specimen Volume: 5 mL

Collection Instructions:

1. Collect a preservative-free, random urine specimen.

2. If specimen is at ambient temperature, aliquot the urine to a urine myoglobin transport tube (T691) within 1 hour of collection. Refrigerate specimen.

3. If specimen is refrigerate, aliquot the urine to a urine myoglobin transport tube (T691) within 2 hours of collection.

Additional Information: Urinary myoglobin is highly unstable unless alkalinized with sodium carbonate preservative. Even with alkalinization, myoglobin deterioration is variable and specimen dependent (approximate averages of 10% at 1 day, 20% at 3 days, and 30% at 7 days).

Specimen Minimum Volume Defines the amount of sample necessary to provide a clinically relevant result as determined by the Testing Laboratory

1 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected








Use of any transport tube other than urine myoglobin transport tube (T691), specimens received frozen
