The new guidelines include a Class 1 recommendation (this is the highest level) for universal lipoprotein(a), or Lp(a), screening in all adults. Lp(a) is a type of cholesterol particle that is largely determined by your genes. Unlike regular LDL, which responds to diet and lifestyle changes, your Lp(a) level is mostly fixed at birth. High levels significantly increase your risk of heart disease and stroke, and most people have no idea what their numbers are.
