title: By the way, doctor. As a regular reader of your newsletter, I have a pretty good idea of what a healthy person's cholesterol and triglyceride levels should be. But last year, I had a couple of tests, and the results were completely different. According to the first, my triglycerides were 285, my HDL 31, and my LDL 109. Eight months later, the same measurements came in at 175, 44, and 109. What could cause such a big swing? Is it something I should be worried about?
