Участник @ив написал в Подозрения на ВИЧ:
@святой-банан заучи повторю гид.
Вань, я тебе щас еще раз ссылку кину на гид. от твоего любимого ВОЗ. Хочешь? Там черным по-белому написано:
“Individuals whose specimens test negative on the initial HIV screening should be considered noninfected
unless the patient presents with symptoms of primary HIV infection or has a history of recent
(≤6 weeks for fourth generation assays, ≤12 weeks for other assays) high-risk exposure.”
То есть человека можно признать ВИЧ-отрицательным если у него отрицательный тест, нет симптомов и последний риск был больше чем 6 недель назад для тестов 4го поколения (и 12 для других).
Также есть дополнение: "If a patient presents with clinical symptoms suggestive of HIV infection or AIDS and the HIV screening tests are repeatedly negative, then referral of the specimen to a specialized laboratory for analysis using alternative tests to exclude uncommon HIV strains is recommended. "
То есть, если у пациента есть симптомы указывающие на ВИЧ или СПИД при отрицательных тестах то рекомендуются другие тесты в специализированных лабораториях для исключения редких штаммов
