The classic oral glucose tolerance test measures blood sugar levels over a period of 3 hours. Some doctors simply get a beginning blood sample, followed by a sample 2 hours after you drink the glucose solution. If you donât have diabetes, your blood sugar levels will rise and then fall quickly. If you do have it, the levels rise higher than normal and donât come back down as fast. If the test shows that your levels are between normal and diabetic, you have what doctors call impaired glucose tolerance (IGT). People with IGT donât have diabetes yet. If you have a high blood sugar level, weight loss and exercise may help return it to normal.

Propagating Blackberries through Suckers & Tip Layering. Suckers are one of the easiest ways to root blackberry plants. Suckers can be removed from the parent plant and then replanted elsewhere. Tip layering is another method that can be used for blackberry propagation. This works well for trailing types and when only a few plants are needed. Tip layering usually takes place in late summer/early fall. The young shoots are simply bent over to the ground and then covered with a few inches of soil.
