If my total cholest is 284 with hdl 100.9 and ldl 177 , trig 79, ratio 2.81. what is more important the levels or the ratio? what the ratio means?

Individual Values: Cardiovascular (cvd) risk is related to the number of LDL particles (ldl-p) and the number of HDL particles (hdl-p). When ldl-p is high or hdl-p is low cvd risk is elevated. Ratios report an LDL number divided by hdl. However, cvd risk can vary by 40% a the same ratio value. This is because you can get the same ratio with different LDL or HDL values (e.g., 2000/50 or 1000/25 give the same ratio).

Actual LDL&Large-HDL: Cholesterol is a fat made by every body cell, not best test, ldl-c is calculated, not measured, cheaper but often misleading. Ldl & HDL are lipoproteins, i.e. Protein particles which carry all fats in the water outside cells. Ldl is always in nmol/l, best <700, HDL in µmol/l, best large-hdl >10. See NMR particle test, <$100. Ldl particles are the primary driver of artery ds. Large-hdl slow/regress.
