The term PGD, preimplantation genetic diagnosis, is often loosely used to refer to any testing performed on an embryo prior to it being transferred to the uterus. However, the distinction should be made between the terms PGD and PGS. 1  PGD, preimplantation genetic diagnosis, involves removing a cell from an IVF embryo to test it for a specific genetic condition (cystic fibrosis, for example) before transferring the embryo to the uterus.
Hepatitis B E Antigen (HBeAg) If the HBeAg test is positive, it means that: 1  You have high levels of the hepatitis B virus in your blood.  You may be very contagious to others.
Response from Dr. DeJesus. If your test results for hepatitis B came back as Non-reactive that is actually very good news. It means that you have never been exposed to the Hepatitis B virus, so you do not have the virus. Patients that have never been exposed to the hepatitis B virus should consider receiving vaccination for hepatitis B (a series of 3 shots), so they can not catch this infection in the future.
