Reflex Tests
Test Code Test Name
6022U Specific Gravity Confirmation, Urine
Specimen Type
Urine
Requested Volume
3 mL
Minimum Volume
1.1 mL
Special Handling
Collect sample at end of shift.
The acidification of the urine with 1.0 mL acetic acid per 100 mL urine will prolong the stability of the analyte.
