User :   Hi...I have a question about a recent urinalysis that I had. I went in for an annual physical and was given a dipstick urine test. It came back with a trace amount of protein and a specific gravity of 1.025. I had been fasting and also not drinking much water so I thought the concentration of the urine could have been the reason for the trace reading. Below are the results of 3 consecutive dipstick readings...
Test 2: +1 (had been working out the day before test)
Test 3: trace with specific gravity of 1.025
Test 4: negative with specific gravity of 1.005
It was recommended that I take a 24 hour urine protein test just to be on the safe side, which I did. The results came back in the normal range. I was told there was no need for follow up or referral since the 24 hour test is the definitive test to show the amount of protein. Would you agree that based on the 24 hour test I should not be concerned? I am 27 years old, feel fine and have no family history of kidney problems.
Doctor :   Hi
Doctor :  
let me read
Doctor :  
dip stick tests are screening tests and are no the accurate tests
User :   I should also mention that all blood test results were in the normal ranges
Doctor :  
it is the 24 hour urine protein analysis which is the accurate
Doctor :   if there is no abnormality in the 24 hour urine test than it is final no further investigation is required
User :   Would you say that the 24 hour urine test is accurate most of the time?
Doctor :  
User :   Have you seen other patients who had consecutive trace amounts or more and then the 24 hour test showed no problems? I think I may have been a little dehydrated with the dipstick tests.
Doctor :  
nothing to do with the dehydration
Doctor :  
in dehydration it is the specific gravity which will
Doctor :   vary
Doctor :   as i said dip stick tests are the initial tests and in case it detects
Doctor :  
any abnormality a 24 hour urine protein is done
Doctor :   to confirm the dip stick readings
User :   All of the trace results and the +1 were specific gravity of at least 1.020 or 1.025. Would you say this could have an effect on the results? That the urine was overly concentrated?
Doctor :  
i shall not comment on the dipstick method results when 24 hour urine sample results are available which is more reliable
User :   So because the 24 hour results came back in the normal range you would say with confidence that my kidneys are functioning as they should be?
Doctor :  
and when the higher test like 24 hour urine sample is clear with proteins in the normal range
Doctor :   yes
Doctor :  
and you no need to worry at all
User :   Is it also safe to assume that if there was a problem with my kidneys that my BUN & creatinine blood tests would have been outside of the normal range?
Doctor :  
if there is problem with kidney definitely there will be altered numbers of BUN and creatinine
User :   Okay...last question....I have heard that the 24 hour urine protein test can give you an inaccurate result if test is not done correctly. I was told to urinate in toilet when I woke up first morning, in container over next 24 hours, and in container when I woke up next day. I was not told it had to be exactly 24 hours. I urinated in toilet around 7:30 am first morning and in container it was about 7:00 am next day. So it was a little under 24 hours. Would you say this test was still accurate?
Doctor :   yes it is still accurate
User :   Okay...great. Well thank you very much for your help. You would relieved some of my fears.
Doctor :  
is there anything else i can help you with?
User :   No...I believe that is all. Thank you!
Doctor :   thank you for consulting health care magic
Doctor :   bye for now
