Is the total cholesterol the sum total cholesterol or is it total non-HDL cholesterol (only including LDL+VLDL)?

To make it clearer, HDL+LDL+(Triglicerides/5) – memostotle Sep 25 2011 at 0:18

You shouldn't worry about total cholesterol at all, if your trigs are down adn your HDL is high enough, everything is fine. Relax

Well within reason, if your TC is somewhere 180-250 its propably optimal. I doubt something like 300-460 is any good. Atleast havent seen any evidence to support that. – Jan Sep 25 2011 at 5:00
If your trigs are in check, so will be your tc. – MasterB Sep 26 2011 at 0:11
Jan2- My Trig is 57, HDL is 81 and total is 345...always happens when I add home rendered pork cracklings to my diet. All that LDL is going to be the benign , light fluffy variety with the trigs and HDL as they are. – Richard N Sep 27 2011 at 23:49

Jeff's calculation is right and this is why total cholesterol is an idiotic number. There is no reason to add, it just obfuscates what is going on. Adding a positive correlated number to two negatively correlated numbers is going to harm the predictive power.

People want to use cholesterol as a linear predictor but it cannot be well used that way because of its construction.
