Hoping someone can help. After previously testing with a Libre, in recent days I have been testing with a human meter with some success. My question is, how long does it take food to raise the blood glucose level? The reason being he is very hard to test when he is ferociously hungry first thing in the morning. He will swipe at me and it’s nearly impossible to get blood when I’m here by myself. After he eats, 5 minutes later, he lays down on the couch and it’s very easy to successfully draw blood.Is this too late to test him?
