Huntington's disease is autosomal dominant, so essentially you're going to get it or not. I don't believe counsyl tests for Huntington's, and probably only tests for recessive traits where you can be a carrier like cystic fibrosis. I can kind of understand that logic with Huntington's but I'd be surprised if it applied to recessive traits as well.
