1. The other numbers all do look like thal minor. It may be a beta+ that is mild and results in a lower HbA2 or there could be a delta deletion as well, which would lead to lower HbA2, or even a coinciding alpha deletion. The low MCV and high RBC, though definitely look like thal minor.
2. IVF and PGD can be used to pick an embryo that does not carry thal. For determining the status of the fetus, amniocentesis can be used later than CVS.
3. The CVS test would catch if the fetus carries 2 thal genes, as in intermedia.
4. Minors can sometimes become intermedia if the beta gene defect is dominant. This is rare.
5. It won't make any difference in the CVS if you both carry the same gene mutation. Both will be seen.
6. DNA analysis can be done if needed to determine the specific gene mutations. Alpha will be found only if they run a DNA test for alpha thal. The beta test won't look for it.
7. Yes, IVF and PGD is an option but it requires both patience and the funds to do it.
8. Family members should all be checked when thalassemia is found in a member of the family.
