There are two key indicators of an FH diagnosis:

• High levels of LDL-cholesterol, which do not go down with dietary modifications;
• Family history of early heart disease and/or heart attacks.

If you suspect you have FH, consult your family physician. The physician will order the necessary blood work called a lipid panel which is a blood test showing your HDL-cholesterol, LDL-cholesterol, total cholesterol, and triglycerides levels. Usually, LDL-cholesterol levels and family medical history are enough for a clinical diagnosis of FH. If the results and family history indicate that you may have FH, your physician will refer you to a cardiologist, lipid specialist (expert in cholesterol disorders) or geneticist. An FH diagnosis can be confirmed by a genetic testing. The main difference between Familial Hypercholesterolemia and lifestyle-induced high cholesterol is the “familial” aspect. FH is inherited high cholesterol and is not caused by unhealthy eating. This is why it is extremely important that you are aware of your family’s medical history and you report it to your physician.
