orthostatic albuminuria

The presence of small amounts of albumin in the urine in the absence of demonstrable kidney disease. The condition occurs rarely in young people. Urine formed during the night while the affected person is recumbent is free from albumin. Orthostatic (or postural) albuminuria is not believed to be of significance.
