美國的臨床檢驗血樣（或者尿， 腦脊液和其他樣品）用過後還會儲存多久？我所知道的州， 法律沒有硬性規定。隻能由醫院實驗室自行規定。。。從quora上看，其他地方差不多。

總的說，無法儲存多久， 因為醫院或診所沒有space。銷毀這些medical waste 很花錢。不按照規定，亂扔medical waste，後果非常嚴重。

儲存的樣品還能用於其它目的嗎？看情況，如果病人知情權沒問題的話，樣品技術上是否合適呢？比如測抗體，對血樣抗凝劑有一定要求。

下麵兩個quora是不一樣的。

It is usually saved for predetermined time period decided by the laboratory director and medical director sometimes approved by the staff. The specimen are saved and controlled refrigerated temperature to preserve their viability for possible retesting or additional tests required. Usually kept up to two ( 2 ) for documentation purposes mostly : quality assurance of correct specimen and proper testing. In other CYA ( cover your “ you know what “ purposes)

After this time the samples are no longer any good for testing and the predetermined time of detainment has expire the specimens are discarded in biohazards bags/ containers.

At our lab we had a “ biohazards disposal company “ pick up these properly disposed of specimens. Then these specimens are brought to a special incineration facility that incinerates the sample with super special incineration vents as to not aerosolize any biohazards into the air.

All standardized by the EPA for the public’s protection!

The specimens are stored either room temperature, in a fridge, or freezer.

Lab protocols are different, but generally, room temperature specimens are stored for one shift or one day, refrigerated specimens are kept for one to two weeks, and frozen specimens can be stored anywhere from a month to a year (rarely).

The specimens that have expired are tossed in a biohazard bag/container and are handled as biohazard material; this can include autoclaving, incinerating, or some other means.
