The tests were not as comprehensive as my lab tests from my annual wellness checkup. I thought the video of the results was unprofessional and clunky. It was obvious that these are standard videos made for all customers and not really tailor-made as professed. I did go on to find out more about the GGT results and found that this test is very sensitive and results can be skewed by consumption of alcohol within 24 hrs of testing. I do appreciate the warning, nonetheless. If you don't have access to yearly blood tests, then this is a reasonably priced alternative, however.
