Hi, my first blood test was conducted Oct 09, back then, my Gamma GGT level was 76 which is considered very high for my age (38). i had another test done recently (8 months later), it shows 52. the day before my test i have stared medication to treat possible urine or kidney infection. i don't drink alcohol. BTW, all other test values are within normal range. could you advise, should i be worried about the results? i am 160cm tall, 60kg.
