HI my liver function test was 64 when I had a blood test (for a company medical), the doctor hasn t called me back in to discuss just sent me a print out which I submitted to the company doctor with the medical form, but I noticed on the results it said it should be 40, so really I just wondered if I should be concerned at all. Oh & I m male 30yrs old, healthy BMI of 21, non-smoker Thanks Mate
