Detection of Atherogenica Ypoproteins

In the seventies, somebody came up with a formula that here's a way of at least estimating or lating eld else. So is framminghem started calculating eldi, el calestral, the o. What they're doing is they're directly measuring total cluster,. Opserum, they precipitate out the h, d ll, and you could measure trigles rides. Now the formula for estimating e, d l calestral became total calestra minus h d l, callestra minus trigles rides over five. Ye. That's theoretically the gold standard. But to have real world tests, chemists had to develop direct assay. so h d ssays
