Can you diagnose familial Hypercholestrolemia without a genetic test like with symptoms, my father had high  cholesterol and high triglycerides, he is 55 years old, except him only one other family member has cholesterol which is recently diagnosed (she is 65+ years old, plus sibling of my father) although my lifestyle is too much bad to conclude fh, i am overweight bmi -28 (had a bmi of 30) but i am 21 , used to eat a lot of junk food(a lot means alot) like daily and even if i have fh lets say how to like diagnose it properly with some test or things like that and where?
