Q. I’m writing a paper for school and haven’t found this answer; How do you test for HD? I originally thought it was a blood test but need to know for sure.

Thanks, Darci

Ask a question

A. Hey Darci,

Great question! Your original thought is right, it is a simple blood test that lets people know how many CAG repeats they have on the gene that can cause HD.

Good luck with your paper.

Take care,
