Causes of blood +1, ketone +1.5, in one sided nephrectomy patient, non diabetic?

Urine findings. Ketones, in the absence of glucose, in a urine analysis are an indication of starvation and are nothing to worry about. Blood in the urine (b) can be due to various factors. Among them are, a uti, kidney stone, bladder or kidney cancer and glomerulonephritis, among others. If the b in the urine persists and is not due to a uti, see a urologist for its diagnosis.
