美国的临床检验血样（或者尿， 脑脊液和其他样品）用过后还会储存多久？我所知道的州， 法律没有硬性规定。只能由医院实验室自行规定。。。从quora上看，其他地方差不多。
总的说，无法储存多久， 因为医院或诊所没有space。销毁这些medical waste 很花钱。不按照规定，乱扔medical waste，后果非常严重。
储存的样品还能用于其它目的吗？看情况，如果病人知情权没问题的话，样品技术上是否合适呢？比如测抗体，对血样抗凝剂有一定要求。
下面两个quora是不一样的。

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.

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.
