Can I collect urine sample at home?
Yes, urine samples may be collected at home but should be provided to the laboratory within an hour.
Abnormally high levels of protein in urine mean?
Excessively high levels of proteins may be a sign of an underlying disease, such as:
High blood pressure.
Can I drink water before the test?

Normal characteristics of urine analysis are:
Volume: 1.2 – 2 L/day
Color: Amber yellow
Odor: Aromatic odor
pH: 4.5 – 8.0
Positive urine culture: The presence of a single type of bacteria growing at high colony counts is considered a positive urine culture.
Negative urine culture: A culture that is reported as "no growth in 24 or 48 hours" usually indicates that there is no infection. If the symptoms persist, however, a urine culture may be repeated on another sample to look for the presence of bacteria or other microorganisms that may cause these symptoms.
