She should also know her HBeAg status, but I guess it's negative with hbv dna und.
If it's quantitive result, I guess it is because its in IU, that's very low, so good result, there is a chance to clear naturally after some years.
Did she make hbv dna quntitive test too ?
She has 2-3% chance per year to clear the virus without any treatment but she should do liver ultrasound at least once a year even if she will clear the virus.
