Abstract
OBJECTIVE: To analyze the prevalence of prenatal tests of pregnant women and factors associated with variation in this prevalence in the years of the Brazilian National Health Survey 2013 and 2019. METHOD: A cross-sectional study, carried out with women who underwent prenatal care, interviewed in the Brazilian National Health Survey 2013 (n = 1,851) and 2019 (n = 2,729). RESULTS: The most prevalent tests were urine and blood, and the least prevalent were syphilis and HIV. During the period, the number of tests for syphilis (15.2; 95% CI: 11.0; 22.0) and HIV (4.3; 95% CI: 4.3; 8.0) increased, but the number of tests for the others decreased. The prevalence of tests for the four tests increased and reached 69.9% (95% CI: 67.0; 72.8) in 2019 compared to 60% (95% CI: 56.1; 63.9) in 2013. CONCLUSION: There was a greater number of prenatal tests performed, specifically for syphilis and HIV, rather than a reduction in the number of blood and urine tests. Despite the increase in access to all tests for the most vulnerable groups and locations in the country, prevalence in these groups is still low.
