Hi Pleasance,
I'm glad to see some progress with ferritin level, even if only a small decrease. The SGPT and SGOT are both in a good range, so no worries there. The serum creatinine seems quite low, which makes me wonder about the accuracy of the test. But it's not high, so that's not a concern either. The urine protein level is also normal.
My reaction is you are going in the right direction and your child is tolerating Asunra well. She is on the right dose, so let time and Asunra do their work and see how things look in a few months. Regular chelation compliance is the key. She will do well as long as chelation is daily. Once her ferritin comes down to a safer range, the Asunra dose may be revised, but for now, keep things as is.
