417F推: 19例有14例偽陽，這已經不是盛行率的問題36.229.34.130 05/21 22:46
418F→: ，而是試劑的問題了。36.229.34.130 05/21 22:46
495F推: 我們母數放大1000倍，假設19000人，盛行36.229.34.130 05/21 23:31
496F→: 率很低，裡面只有1個人染病。假設這試劑36.229.34.130 05/21 23:31
497F→: 很差，特異度只有50%，所以會有9500人左36.229.34.130 05/21 23:31
498F→: 右偽陽，9500人左右是真陰。這麼差的試劑36.229.34.130 05/21 23:31
499F→: ，在這麼低的盛行率下，偽陽率是50%(950036.229.34.130 05/21 23:31
501F→: /19000)。現在這結果的偽陽率(14/19)還高36.229.34.130 05/21 23:31
502F→: 於50%。要不解釋成是抽樣的運氣不好，剛36.229.34.130 05/21 23:31
503F→: 好抽到偽陽的居多，如果是這樣的話，這個36.229.34.130 05/21 23:31
504F→: 數字沒有討論的意義。要不就解釋成試劑或36.229.34.130 05/21 23:31
505F→: 檢驗的方式有問題，導致更低的特異度。這36.229.34.130 05/21 23:31
506F→: 不會是盛行率的問題，你可以試著用更低的36.229.34.130 05/21 23:32
508F→: 盛行率算算看，怎樣才會出現14/19這樣的36.229.34.130 05/21 23:32
509F→: 偽陽率。36.229.34.130 05/21 23:32
