Hi, Thanks for writing in. What you have is a condition known as microscopic hematuria. The causes include conditions which needs to be investigated because you also have proteinuria ( Albumin 3+) and this is present for last 5 years. There is a possibility of a primary renal disease in your situation. The main problem could be in your kidneys. There are small units of the kidney known as gromerular apparatus. The blood passes in thin capillaries through this apparatus and gets filtered and urine is form which further moves to the tubular system and then out of the kidney. In this filtration process, due to disease in the glomerulus, small amount of red blood cells and proteins come into the urine. This is a medical disease and often treatment with medicines may be required. A kidney biopsy may be required to pin point the diagnosis. Please consult a nephrologist for further management. Hope this helps.
