Can anybody help me understand this a little better as am a bit confused. These are the results from my latest Hba1c for cholesterol. Serum cholesterol: 5.7mmol/L Serum HDL cholesterol level: 1.81 mmol/L If my total is 5.7 and the HDL is 1.81 does this mean that the difference is the LDL?
There is also a 4th factor which is Triglycerides. This calculator and the various references it contains will probably tell you most of what you need to know. http://www.hughcalc.org/chol-si.php
Probably gave you those two figures because the ratio is the important one. Total/HDL should be 3.5 or less. You ratio is 3.15 so that seems to be O.K.
As I'm a registered HCP I cannot give you advice; but I could suggest that you visit a website that you may find interesting, particularly one of the books mentioned. The website is a blog written by a practising GP and health sceptic https://drmalcolmkendrick.org/. He discusses cardiovascular disease and diabetes.
