When only a single test, Hepatitis B Surface Antigen, is ordered to diagnose Hepatitis B in a pregnant woman, additional tests such as liver enzymes should be ordered to confirm the diagnosis. If RPR screen is reactive, RPR Titer and FTA Confirmatory testing will be performed at an additional charge.

Genetic education is warranted for the better implementation of ECS.Ĭhinese Hong Kong expanded carrier screening recessive disorders. In addition, more than half of male partners whose wives were carriers declined any types of sequential testing possibly due to a lack of awareness and knowledge of genetic disorders. Our study demonstrated that a small-size ECS panel could yield comparable clinical value to a larger-size panel when the carrier rate of the individual condition is equal or greater than 1%. Eight at-risk couples were identified and four of them performed prenatal diagnosis. Sequential testing was performed in less than half of male partners. The estimated at-risk couple rate was 0.83%. A total of 1321 women performed ECS successfully and the overall carrier rate was 19.23%.
The reproductive decision and pregnancy outcome were surveyed for at-risk couples.
Sequential testing of their partners was recommended for women with a positive carrier status. An ECS panel containing 11 recessive conditions was offered to Chinese pregnant women below 16 gestational weeks. The aim of this study is to evaluate the feasibility of a small-size ECS panel in clinical implementation and investigate Chinese couples' attitudes towards ECS. Demands for expanded carrier screening (ECS) are growing and ECS is becoming an important part of obstetrics practice and reproductive planning.
