Familial Hypercholesterolemia (FH) Genetic Testing
Detects: Inherited very-high LDL cholesterol (familial hypercholesterolemia)
What it is
A test for the gene changes that cause FH — an inherited condition that keeps LDL (“bad”) cholesterol very high from birth and sharply raises the risk of early heart disease if untreated.
Who it’s for
Adults or children with very high LDL, a personal or family history of early heart attacks, or a known family FH mutation. Finding it early means it's highly treatable.
How it works
Typically a mail-order saliva or cheek-swab kit sent to your home; you return it by prepaid mail and results go to your provider, who can guide treatment and family testing.
The guidance
FH is one of the most common inherited conditions and is under-diagnosed. Identifying it lets providers treat aggressively and screen relatives (cascade testing), per lipid and cardiovascular guidance.

Do I need a doctor's order for FH genetics?
Yes — genetic testing generally requires a provider's order or prescription, and it is subject to insurance or Medicare approval. Check with your provider.
