Also, I want the egg donor to do genetic testing of blood to detect hereditary genetic diseases. Will you be willing to do that? Most IVF clinics in Malaysia won't be willing to carry this out, because they can make much more money by doing genetic testing of IVF embryos - PGS or PGT-A. I will have to arrange for a private genetic testing company outside to do this, with all costs borne by myself, but this would still be much cheaper than PGS.
A blood sample contains thousands of white blood cells, from which an abundant amount of DNA genetic material can be extracted. By contrast, only a few cells and tiny amount of DNA are extracted from the embryo during PGS (biopsy procedure). This makes it technically simpler and much cheaper to do genetic screening of the Egg Donor's blood sample, as compared to genetic screening of embryos with PGS / PGT-A.
