>How long does it take to get a DNA result?

A: The actual analysis doesn't take terribly long - say overnight. Preparing
the samples for analysis takes longer - a day to a week or more, depending
how much evidence is submitted. (The huge number of samples from the 9/11
incident and the Oklahoma City bombing took
many months to process.) The reason it takes most labs a long time to return
results is that nearly all of them have tremendous backlogs of evidence
waiting to be analyzed, and unfortunately the trend is that the backlogs are
increasing rather than decreasing. In our lab, it may take only 30 minutes to
actually analyze a particular exhibit - but it takes about 6 months to work
through all the other cases that were submitted before that one. Our
turnaround time has increased
from about 2 months to about 6 months over the past 2 years, mostly because
we've had a huge increase in the number of cases that are submitted to us for
analysis during that time.

DNA分析需要花多久的時間？
其實分析本身的時間不會很長，大約隔夜就會好。真正耗時的是準備樣本的時間，
可能是一天、一個禮拜，也有可能更多；這取決於交到我們手上證據的多寡。
〈在911以及奧克拉荷馬市爆炸案所蒐集的證物花了數個月才分析完畢〉
幾乎所有的實驗室都有囤積下來的工作，這才是分析耗時的原因。不幸的是，
囤積量只有增加，沒有減少。在我們的實驗室中，分析一件證物的時間可能只
需30分鐘，但我們可能得花六個月的時間，才能把在它之前被送進來的東西分
析完畢。我們的案件周轉時間在過去的兩年中，已從兩個月增加為六個月。
因為交給我們實驗分析的案件，在這段時間中大幅的增加了。
