Uptake of non-invasive prenatal testing in Chinese women: money matters.

ABSTRACT

OBJECTIVE: To determine the influence of free invasive prenatal testing on the uptake of non-invasive prenatal testing (NIPT). STUDY DESIGN: Over a 2-year period at a Chinese tertiary prenatal diagnostic unit, women at risk of fetal trisomy were given the option of NIPT or invasive prenatal testing. Invasive prenatal testing was offered free of charge to women with a local Hukou (household registration); however, women without a local Hukou were charged for invasive prenatal testing. Both women with and without a local Hukou were charged for NIPT. RESULTS: During the first year, 2647 women with a positive trisomy 21 screening test were referred (474 women with a local Hukou and 2173 women without a local Hukou). Only 1.6% of the women with a local Hukou underwent NIPT, while this proportion was 20.6% in the women without a local Hukou. During the second year, the price of NIPT was reduced. The total number of women referred was 3047 (502 women with a local Hukou and 2545 women without a local Hukou). The uptake of NIPT in women without a local Hukou doubled, but the uptake of NIPT remained stable in women with a local Hukou. CONCLUSION: The financial impact on the uptake of NIPT should not be underestimated.
