could someone explain what no ldl means

[LaurieFairyCake]

I've just been to the doc and they're repeating a blood test as I have very low ldl cholesterol and over 7 hdl - he says the gaps very bad
And he talked about statins

I'm not googling as I don't do that for health things - could someone provide a very simple, for total idiots explanation

He basically says I had no ldl at all

Are you sure you have that correct? Cholesterol which causes blocked arteries comes in two forms, high density lipids (HDL) and low density lipids (LDL).

I could understand his concern if your LDL was 7 and your HDL was non-existent.

I could be wrong and have someone else in mind, but I thought you were a HCP?

Did you ask the GP to explain or was his explanation just not very good? It's good cholesterol vs bad cholesterol I thought. If you have high levels of both think they cancel each other out so that's why the gap going the wrong way is an issue.

No I'm not sure I have it correct, I couldn't hear it properly - one was 2.1 and one was 7.6 and I thought he said the hdl was the high one
