Positive 24-hour urine protein is not necessarily a kidney disease, but may also be caused by strenuous exercise or mental tension.
Patients with positive 24-hour urine protein may be caused by strenuous exercise or mental overstress before doing the examination, etc. The occurrence of the above conditions may lead to renal vasospasm, which increases the permeability of glomerular filtration membrane and easily leads to the presence of protein in urine, causing positive urine protein. This condition is not a kidney disease.
Usually, 24-hour positive urine protein is mostly kidney disease, and common diseases include glomerulonephritis, lupus nephritis, diabetic nephropathy and tubular acidosis.
Patients with positive 24-hour urine protein should go to the hospital for further examination to identify the specific cause of the condition and receive treatment.
