It was a very thorough test and I like the explainations on the portal, however I would like to speak to someone so I can review my results. I am not a physician so I need some guidance.

I felt like the write up of the clinicians summary and notes were very good. I felt like they really looked at my information and took into consideration my thalassemia diagnosis. I feel there are specific things I can act on prior to my 6 month recheck. Very happy with my information.
