Dear Janice Thomas
Your description suggests that your father is suffering from an acute inflammation in the kidneys. he can be loosing blood in the urine because the filters (glomeruli ) in the kidney have become leaky.
It is important to know the cause and type of damage in the kidneys.
Blood and urine tests can only suggest the possible problem. Only a kidney biopsy
can give a clear picture on the extent and type of damage, which can help plan the exact treatment.
Kidney biopsy is a fairly safe procedure in experienced hands, with minimal risk.
