Normal: You did a screening test with 75g of glucose. A result under 140 is considered normal. If it was above 140 you would have had a full glucose tolerance test with 100 gm. You do not need to worry. ...Read more

Not likely: Even though you did not follow the protocol, given the other results, you are not likely to have failed the test had you stayed put as required.

Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more
