Sensitivity and specificity of the LYNX test by agea. a Birth = 0–6 days; postnatal = 7–28 days; 6 weeks = 4–13 weeks; 6 months = 3–7 months; all routine after birth = 6 weeks, 6 months or > 7 months. Note: Error bars represent 95% confidence intervals. One child who initially tested positive by the central lab and negative by the LYNX test at 7.9 weeks of age was found to be HIV uninfected after confirmatory testing at multiple visits, increasing sensitivity of the LYNX tests at 6 weeks to 83.3 and 82.9% at all routine visits after birth
