Absolutely NOT. DD is fed a nutritious diet, is healthy and active and a normal weight for her height. How many children die of high cholesterol? What is the purpose of testing?

If it shows a genetic predisposition then clearly a diet low in saturated fat should be followed. If it doesn't....well, then a diet low in saturated fat should be followed. There aren't people who can eat as much fat and junk as they like and it's good for them! I would not subject my child to potentially traumatic medical testing to see if she has a predisposition to something which would have to be dealt with far later in life.

If i fed her a lot of rubbish and she was too fat then MAYBE, but even then, surely modifying the diet is far more use than getting a blood test...?
