i wouldn't freak out about it...by the way were you fasting when you had the test? That can make a difference.
A few years ago my cholesterol was tested high during a regular blood test, and i got worried because heart disease runs in my family. If anything my cholesterol was always LOW. As it turns out, it was due to a thyroid condition. ANd when I tested again it was normal, and I was tested when fasting. SInce then it's been normal. THere could be something that runs in your family to keep an eye on, and it's entirely possible that next time you'll test normal. in the meantime, try and watch the cholesterol in your diet, don't eat too many eggs, forget the butter, etc. The good thing about low cholesterol diets is that it's not like you have to eat birdseed and lettuce.
