疑犯 DNA 認證最短需要多久？

周克華上午六時許被擊斃，下午在新聞發布會中警方就確認其DNA與重慶哨兵槍殺案疑犯的DNA匹配，請問這樣的速度符合實際嗎？

How soon can I expect the results?

We offer the fastest DNA paternity testing anywhere. Need results the same day? We must know your samples are arriving before 9:30 am so we can hold up the early morning PCR (DNA amplification). Your results will be out the same day. Our standard one day STAT testing option guarantees results on the following business day (from the day the lab receives the samples) or within three business days with the 3 Day STAT. Our routine turn-around time averages 5 business days. These turn-around times are based on testing with cheek swab samples only. With any biological testing, however, exceptions can occur. There are a few reasons why your test might not be completed in the typical time.

即使是個人想在此公司做DNA 認證，9：30前提供樣品，加急，當天可以拿到結果。如果警方能夠找到實驗室專門做，我認為可以更快些。

如果要質疑，我覺得就只有「前一個案子的DNA樣本保存的有多好「這條了。
