Note on sensitivity and specificity data

Where available, we list the manufacturer-reported sensitivity and specificity data.
A highly sensitive test should capture all true positive results.
A highly specific test should rule out all true negative results.
These measures are not independently validated by the Johns Hopkins Center for Health Security.
If sensitivity or specificity is not listed, it was not available from the manufacturer at the time of posting.
When available, the number of samples used for sensitivity/specificity definitions are listed in the product description.

關於敏感性和特異性數據的注意事項

在可用的地方，我們列出了製造商報告的敏感性和特異性數據。
高度敏感的測試應捕獲所有真實的陽性結果。
高度特定的測試應排除所有真實的陰性結果。
這些措施未經約翰霍普金斯大學健康安全中心獨立驗證。
如果未列出敏感性或特異性，則發佈時無法從製造商處獲得。
產品說明中列出了用於靈敏度/特異性定義的樣品數量（如果有）。
