My doctor requested I take a glucose tolerance test because a score of 103 that came back for blood work I had done for a complete physical. I had fasted for 10 hours prior, per the doctor’s instructions for the physical. I also fasted for 10 hours for the tolerance test. Here’s how the tolerance test was administered. After fasting for 10-12 hours minimum, they draw blood prior to giving you the sugar drink. One hour after the sugar drink they draw blood again. Another hour later, they draw blood for a third time. The results were as follows: 1. (87) 2. (120) 3. (106). The women that I spoke with from the lab could not answer my questions regarding the second and third numbers. All she could tell me was that the first reading was normal and I had nothing to worry about. I left a message for a callback from the doctors nurse but this office is notorious for slow callbacks. I understand the first reading is normal and I’m very happy about that! But, I’m curious to know how good, bad or normal are the 2nd and 3rd numbers? Also, how can I score a perfectly normal 87 this time, when just two weeks ago I scored a borderline 103? Both times I fasted for a 10 hours and drank water only. Thanks for reading my long post, and any insight would be appreciated.
