Dear Doctor, This 73 year old gentleman had been awaiting a knee operation, but this was cancelled as a result of pre-operative blood tests revealing altered renal function. We repeated these tests and these show U 7.2, Cr 185 and eGFR 31. He also had a macrocytic anaemia, and a GGT of 239. He admits to drinking more than he should. His dipstick tested positive for protein and glucose, and he is currently awaiting a GTT as his random glucose was 9.8. We unfortunately have no records of previous blood tests.
He keeps well, otherwise, and his only relevant previous history is osteoarthritis.
We have organised repeat U&E, B12/folate, Ca and PO4, GTT, and urine sample for protein:creatinine ratio. I have also organised a renal ultrasound. I would be grateful for any further advice, or other investigations we should be performing at this stage
