Harpeet,
The child is likely one of two things mentioned in the report. Her HbF is far higher than what is seen in typical beta thal minor, so that alone is unlikely. The most likely possibilities are Delta/beta thalassemia and Hereditary persistence of fetal Hb (HPFH). In either case, these are inherited conditions, so one of the parents would also have to be a carrier. Delta/beta thalassemia is often missed when looking at a complete blood count, so if this is the case, one of the parents is also an undiagnosed carrier.
Neither situation is alarming. Neither requires medical attention. I would suggest further DNA testing to determine the exact status, as this is important to her later in life when she decides to have children. She will need this information so that a partner can be tested if necessary.
