I'm very worried. My serum creatinine was. 96mg/dl 3yrs ago. Now its 1.09. Is it bad? I'm exercising for1 week 2 days before my test. Male 22y/0. 70 kgs

No need to worry. All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. However the result of 1.09 is normal. If your muscle mass has increased from exercise, that would explain this apparent rise in creatinine.
