To test final cost-effectiveness, sensitivity analyses were carried out on the following parameters:
cost of test kits,
both higher and lower maternal HBsAg prevalence,
the percentage of maternal HBsAg carriers positive for HBeAG
uptake or compliance,
sensitivity and specificity of laboratory tests for HBsAg test,
Zero secondary benefits,
risk of infant carrier per anti-HBe positive mother,
and increase in secondary benefits.
All tests were one-way simple analyses and used only one alternative level.
