根據這篇文章(文長,非懶人包,須具備基礎知識)

(一)15 分鐘快篩,可驗出 100% 確診的患者。
 快篩陰性,並非沒病,要繼續隔離。
 隔離期間若出現症狀,就要檢驗核酸,目前技術需 4 小時

(二)媒體誤認「15 分鐘」是比「4 小時」更進步的技術。
 實際上,是用在不同場合的不同技術。

(三)此外,由於臨床已經出現 19 天才發病。
 所以,現在各國普遍是隔離 21 天。

中國快篩試劑有多爛?「西班牙烏龍案」媒體說不清楚的病毒科學

文/邱慕天(「前」新聞媒體工作者) 兩天前有一則新聞,是關於西班牙、捷克不滿從中國進貨的新冠病毒「快篩」試劑「錯誤率高達八成」,聲明退貨。《新唐人》是我注意到最早報導這新聞的媒體之一,但後來《自由亞洲電台》、《非凡新聞》等很多媒體都有跟進。這麼多家媒體在茫茫世界大事中選輯這條新聞,符合並加深了一個繁中新聞受眾市場的既定敘事:「MIC=爛貨」。 但在私下聊天討論到這則新聞時,我們立刻感到

第(二)點正確,其餘有誤:
 
■潛伏期本來就非固定數值,多數估計認為潛伏期介於1-14天,的確可能出現極少數例外,但各國普遍【並未】因極端少數例外而延長有感染風險者的隔離/檢疫期間,包括:美國CDC、英國NHS、台灣疾管署等皆採14天,【並未】延長到21天。

■至於「快篩可驗出100%確診患者」【並非】原文連結的觀點,原文形容快篩具高sensitivity、低specificity,並未認為可驗出100%確診患者。
