A presumptive diagnosis of HIV is made with sensitive assays for HIV antibodies. Positive results are confirmed with specific assays like Western blot. Sensitive tests have low false negatives, while specific tests have low false positives.
HIV的初步診斷基於對HIV抗體的靈敏測定。陽性結果需通過印跡法等特異性試驗確診。靈敏測定能有效排除陰性病例，特異性測定則能確診陽性病例。
