En estas directrices se actualiza la sección de recomendaciones sobre la prevención de la transmisión maternoinfantil de las Directrices para la prevención, la atención y el tratamiento de la infección crónica por el virus de la hepatitis B, publicadas por la OMS en el 2015, y se centra la atención en el uso de la profilaxis con antivirales en el embarazo. Su finalidad es proporcionar orientación respaldada por la evidencia acerca del uso de la profilaxis con antivirales durante el periparto en embarazadas que han dado positivo al HBsAg a efectos de prevenir la transmisión maternoinfantil del VHB. Los principales destinatarios son los funcionarios de los ministerios de salud que formulan las políticas nacionales y las directrices sobre la prevención de la transmisión maternoinfantil del VHB en todos los países, pero sobre todo en los de ingresos bajos y medianos. Asimismo, podrías ser útiles para los miembros del personal de salud que tratan a las personas con la infección por el VHB, así como a los que prestan atención a las embarazadas y los lactantes.

This document, prepared by the World Health Organization, outlines the protocol for evaluating nucleic acid tests designed to quantitatively detect hepatitis B virus (HBV) DNA. Aimed at Performance Evaluation Laboratories and in vitro diagnostics (IVD) manufacturers, it details the evaluation procedures necessary for WHO assessment. The protocol addresses various aspects including clinical and analytical performance evaluation, quality control, data analysis, and ethical compliance. The primary goal is to ensure that these tests meet WHO standards, particularly in resource-limited settings. The document serves as a guide for assessing test accuracy, precision, and operational efficiency, while also providing guidelines for specimen handling and data reporting.
