Since I have a free moment…
Here's something else I should have mentioned earlier, but forgot: This is for those people who are concerned about the function of their insulin system, but don't want to deal with the hassle and expense of having blood work done. You can go to most any drug store and buy a glucometer and glucose beverage for around $20 US. This will allow you to test your fasted glucose (for what it's worth) on your own, and will also allow you to to test your glucose tolerance by giving yourself an OGTT (oral glucose tolerance test). For those who don't know, to do an OGTT, get in a fasted state, then ingest a 75gm glucose beverage. I recommend taking a baseline blood glucose reading, and then taking additional blood glucose readings every 30 mins for the first 3 hours after ingestion of the glucose - or until you blood glucose returns to baseline. The faster your blood glucose returns to baseline, the better your insulin system is functioning overall. Without concurrent testing of insulin & C-peptide (which you can't currently do yourself - unfortunately), this test doesn't let you know how hard your pancreas has to work to acheive that. So this test doesn't really differentiate your insulin sensitivity per say, or how well your pancreas is functioning per say, but at least it can give you some idea of how well your insulin system is functioning as a whole.
