My doctor tested both my urine & blood and found a +1 value for protiens. This didnt seem too problematic to the 2nd doctor who said tell me again in 40 years then Ill worry. However, the 1st doctor seemed to pay attention to the symptoms 1) severe lower tummy swelling, I would not call it bloating because it is turgid. 2) swelling of hands, feet & eyes (approximately 2 times the regular size) 3) blood pressure normal for all but high for me 120/80 im normally under 100/70 or so. When urinating I do see foamy small bubbles in the toilet and at one point I did urinate a dark orange brown urine; which subsiquently has turned a normal to a little dark yellow.
