Test Name

Test ID: MYGLU    
Myoglobin, Urine

Specimen Type Describes the specimen type validated for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Container/Tube: Plastic, 10-mL urine myoglobin transport tube (Supply 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 (Supply T691) within 1 hour of collection. Refrigerate specimen.

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

Additional Information: Urinary myoglobin is highly unstable unless alkalinized with Na2CO3 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 The amount of sample necessary to provide a clinically relevant result as determined by the 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)

Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperatures are also included.
