Thank you for your query on Healthcare Magic.
The normal level of Ig A in a 13 years old female child is 148+/-63 mg/dL.
It means your child serum Ig A level is below the normal range.
But the interpretation of the report should be done by your daughter treating doctor in correlation with her clinical problems to suggest any abnormality.
The cause for her exhaustion and paleness should be evaluated further depending on her clinical examination by the pediatrician
Hope I have answered your query.
