if you have low hdl-c you cannot infer if it's low because you are failing to quote unquote pick up cholesterol or because you're delivering it quickly conversely or similarly I should say if you have high HDL C it is not clear if it is high because you pick up a lot which in theory would be quote unquote good or because you're deficient at dropping it off which would be quote unquote bad
