Thanks for writing in.
There are a number causes of an enlarged spleen and liver and a high bilirubin
in children. The fact that you have high haemoglobin
or are donating blood has not effect on this. I would suggest that a bone marrow examination
and a liver biopsy
be done for your child. We should be looking to rule out a metabolic disorder and a problem in the bone marrow. In these conditions, the liver and spleen frequently enlarge.
Hope this helps.
