Protein in Urine

Under normal cir****tances, low molecular weight proteins and a small amount of albumin are filtered through the glomerular capillary wall. As a result, up to 150 mg/d (in adults) or 4 mg/m2/h (in children) of protein in the urine is considered to be within normal limits.
Did you have dipstick or lab urinary analysis?
Negative or trace protein on the dipstick is considered normal, whereas a protein value of 1+ should at least be monitored.
The presence of increased protein in the urine can signify underlying renal disease, although there are a number of false positives/negatives
When there is a concern for a false positive or false negative reading, the amount of proteinuria can be quantified by the urine protein/creatinine ratio on a random urine specimen
A common cause of proteinuria in asymptomatic patients is orthostatic proteinuria, a benign diagnosis, which should be ruled out using a first morning void specimen before pursuing further evaluation.
So My Advice to you:
1- If it was a dipstick analysis,ignore it and go for regular urine analysis
2-If it was a regular urine analysis,do early morning voiding test to rule ou dehydration as a cause,ask your PCP to give you a container,keep it at home,when you wake up in the morning,the first thing to di is to put a urine sample and take it to lab,ask the to do urine analysis and urine protein/creatinin ratio...this will give you the answer
we all know dehydration could cause protein in urine,but this only when we are sure there is no underlying cause,especially if you have hypertension or diabetus
