During a pediatrician visit in August last year, I was given a pathology form to request two blood tests on the Lego lover. One was for chromosome karyotyping and the other was one for fragile X. These are standard tests now done when a child is diagnosed with autism in this state whereas it wasn’t when LL was diagnosed four years ago. It’s unlikely fragile X is anything of concern so it will rule it out. The chromosome thing might reveal something or it might not.
