Discussions, Resources and Solutions To Reduce Bad Cholesterol

Is total cholesterol just HDL + LDL or is there another factor in the total cholesterol number?

I just had a reading and I noticed in the results that HDL + LDL did not equal my total cholesterol number. I just wanted to know if this was normal or if it was a mistkake.

Total is the combination of LDL and HDL. LDL should be under 100 to be in the healthy range.
