How long can a urine sample sit before it is sent to lab for testing without going bad?
A doctor has provided 1 answer
Depends : Some things such as glucose must be tested pretty quick as they are consumed by cells and bacteria in the urine. Cells deteriorate quickly, bacteria multiply quickly. Protein could deteriorate. The ph can change depending upon bacterial action. Sodium, potassium, chloride, an similar elemental analytes are unchanged in spite of temperature and or biologic processes. In general test asap.

Testing for amyloidosis. Two 24-hr urine protein labs both showed protein 6.3mg/dl. 1st test was 140mg/24hrs from volume of 2225ml of pee. 2nd test was 129.2mg/24hrs from 2050ml pee. Both in range, but if peed more would have been over limit. Worry?
