I don't have copies of my first few reports. I will see if they are buried in my patient portal, or call Natera and see if they can explain. I don't see anything on my later reports about how many assays they were able to detect. I do see a note I hadn't noticed before:

"Testing cannot be performed in patients who are pregnant, have a history of bone marrow transplant, or history of blood transfusion within three months."

The transfusion limitation may invalidate some of my results. 🙁
