Cascade screening

What is cascade screening?

FH is an inherited condition, which means it can be passed from parents to their children. For this reason, it is important to identify other blood relatives who are affected through a process called cascade screening.

Who is eligible for cascade screening?

If you have FH, cascade screening then is the process of testing your immediate biological relatives to determine which family members also have the FH gene. First, second, and third degree biological relatives are all candidates for cascade screening.
