Can An Online Doctor Explain My Oral Glucose Tolerance Test Results?

Question : I have a question about the Oral Glucose Tolerance Test. This has been driving me crazy. Please tell me if I'm missing something painfully obvious. Ok so I had the glucose tolerance test done to check for acromegaly and these the results: Baseline GH: 0.2 30 minutes: 0.1 ng/mL 1 Hour: <0.1 ng/mL 1.5 Hours: <0.1 nh/mL 2 Hours <0.1 ng/mL. In the lab report it says: Acromegaly is ruled out if at any point in the timed sequence GH levels are <0.4 ng/mL. Here is where I'm confused. My baseline GH level was already below 0.4 ng/mL. I know my GH did suppress, but I'm worried that what if my GH is partially suppressible and I have acromegaly. I read on the internet that sometimes people suffering with acromegaly have partially suppressable GH, that doesn't suppress below 0.4 ng/mL, but does suppress, just not enough. My IGF-1 is normal at 289 (115-355 ng/mL) by the way. If baseline GH is already below 0.4 ng.mL does that mean that if at that level the GH suppresses at all acromegaly is ruled out(because it is less than 0.4 ng/mL) or does it mean that baseline GH has to be higher than 0.4 ng.mL and then it has to suppress below 0.4 ng/mL to rule out acromegaly? Thank You!!!!!
