There is a false-negative glucose due to oxidizing contaminants.
There is a false-negative glucose due to the alkaline pH.
The specimen is probably old and the bacteria and yeast have consumed the glucose.
Glucose would not be present in the urine specimen since the blood sugar was normal.
Be centrifuged and the supernatant cultured
Be rejected due to possible contamination from routine urinalysis
Not be cultured if no bacteria are seen
Be immediately processed for culture regardless of urinalysis results
Perform the hormone determination, since 600 mL is a normal urine 24-hour volume
Check the creatinine level; if it is less than 1g do the procedure
Report the hormone determination in milligrams per deciliter in case the specimen was incomplete
Check the creatinine level; if it is greater than 1g do the procedure
Red blood cells, leukocytes, and casts agglutinate after standing for several hours at room temperature
Urobilinogen increases and bilirubin decreases after prolonged exposure to light
Bacterial contamination will cause alkalinization of the urine
Ketones will increase due to bacterial and cellular metabolism
