I started this thread a couple of months ago and am slightly surprised by some of its twists and turns, but I guess that's one of the joys of PPRUNE ;-)
Following another blood test my figures are: total cholesterol 4.4, HDL 1.1 and LDL 2.9. My GP has now said that although there is some evidence that they protect arterial walls, with these cholesterol results he can understand why I might be reluctant to take statins.
I was going to use the Friedewald formula (LDL=Total chol-HDL-Total trig/k) to calculate my Total Triglyceride level but references for k seem to give 0.45, 2.19, or 5 (ostensibly all with measurements in mmo/l) ... what have I misunderstood?
