Xavier's blood tests are back, and the news is mostly good! The best news is that the genetics test showed he was negative for Russell-Silver syndrome, which is a huge relief. The second was for IGF-1, which is an insulin-like growth hormone. That one is a bit low at 41 ng/mL, but its hard to tell what that means in someone his age. He will be reevaluated in January, and may need hormone stimulation if he's still not growing well and the IGF-1 is still low.
