I am in the midst of collecting urine for a creatinine clearance test. The lab did not give me any special instructions. I read on the web that you shouldn't exercise for 2 days before. I work out an hour daily. Will this cause my test to be inaccurate?
I had a blood test last week for BUN and creatinine that were normal. I have had an abnormal ultrasound where 1 kidney is large, and tested positive for microscopic blood in my urine. ( I am a 34 year old female, and I wasn't on my period and no infection, and many urine tests tested positive for the blood) Serious replies only
