Testing pediatric urine specimens for
reducing substances other than glucose is a policy that should be implemented in the urinalysis laboratory. The maximum age for this testing is defined by each laboratory and is usually based on consultation with the pediatric clinical staff.
The policy that is implemented in most laboratories is to test urine specimens for other
reducing substances if the glucose test on the reagent strip is negative and the urine specimen is from a child below the age of one. Verify the policy for your own laboratory because the cutoff age for testing may be different.
