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.
Your sexual partner should have the 3-dose series of hepatitis B vaccine and postvaccination blood testing 1 to 2 months (no sooner and no later) after the last dose of vaccine. If your sex partner's test shows adequate anti-HBs (at least 10 mIU/mL), then he/she should be protected against HBV infection.
