- What Does Protein in One's Urine Mean?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: During a recent routine physical examination, my physician took a
- urine test as well as some blood for testing. As I understand it, the nurse
- did a "dip-stick" test on my urine and found that it contained "protein". Now
- I am to start a whole new series of test to see what is wrong. Can you tell
- me what this all means and do you think it is serious?

- ANSWER: All normal urine contains some protein although the quantities are
- small, less than 150 mg in a 24 hour period. However, screening tests can
- detect higher levels and give some indication as to amounts. The "dip-stick"
- is a screening test, using a small strip coated with a chemical that changes
- its color in relation to the amount of protein present. A positive finding of
- the presence of higher than normal levels of protein in the urine (it's called
- "proteinuria") is reported in as many as 10 percent of patients tested with
- this method. In children, adolescents and physically active young adults,
- this may be a situation that is benign (without being caused by a disease
- process), and frequently disappears by itself. In some cases it is the result
- of a "false positive" that may occur when the urine is highly concentrated, or
- when it is contaminated by certain antiseptics. Protein may be found in the
- urine when caused by some illnesses such as infection and fever, and is not
- always the sign of kidney disease. However, while the presence of some
- protein in the urine on a screening test is not necessarily a cause for alarm,
- it most certainly demands an explanation, which may be afforded by additional
- testing and investigations. In some cases the patient, under physician
- supervision, may be able to conduct a series of dip stick tests on himself, to
- see if the results continue to be positive or if there is some pattern to the
- findings. In other situations, more accurate methods of analysis are used to
- determine the amount of protein in the urine. Along with a careful history
- and physical examination, other tests may be used, utilizing x-rays and other
- procedures, to determine the causes of the positive findings. You are well
- advised to continue the testing to determine the exact diagnosis, and any
- treatments that may be required.
