- Questions on Protein in Urine Tests
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: During a routine visit to my doctor, my urine was checked. It was
- the test where the nurse dipped a strip of paper in the specimen. I was told
- that there was some protein in the urine, and that they would check it again
- at the next visit. At the next visit however, nothing was found, and no
- explanations have been offered to me as to the cause of the protein on the
- first test. Was one of these tests in error? Do I have anything to worry
- about? Please try to explain this to me.

- ANSWER: Let's start the answer with a bit of reassurance. You have nothing
- to worry about, the circumstances you describe are very frequent, and both
- tests were probably correct. The method of testing used in your case was a
- dipstick test, where the paper had an area saturated with special chemical
- that is quite sensitive to even low concentrations of protein. Although it is
- quite reliable, other laboratory tests could be used to confirm the presence
- and quantity of protein in the urine. However, in view of the great frequency
- of positive tests found in many individuals, it is a common practice just to
- wait a bit and retest the urine at another time. About 1 person out of 10 who
- come to emergency rooms for all sorts of problems are found to have a positive
- reaction with this test. Usually these results are only temporary, as protein
- can be found in the urine as the result of such things as exposure to cold,
- emotional stress, strenuous activity, seizures, and many other situations that
- do not reflect a disease of the kidney. When this is the case it is labeled
- as "functional proteinuria", and the usual procedure is merely to check the
- urine again when other opportunities, such as another visit to the doctor's
- office, occurs. When the second test is normal, the patient may be reassured.
- While there are times when the cause of the first positive test may be
- apparent, most often, despite a carefully taken history, the reason can not be
- determined, but this is not a cause for worry or anxiety. This is one time
- when you can relax after a positive test.
