Covid-19检测所需的实验室用品再次短缺

就在解决棉签短缺的几周后，研究人员再次面临Covid-19检测所需的实验室用品短缺的问题，短缺的用品包括化学药品和移液器吸头。全国各地做Covid-19检测的实验室都面临着工作积压的问题，导致等待结果的时间长。实验室工作人员需要这些称为吸液管吸头的一次性用品，以便在处理检测时在数个小瓶之间移动液体。移液器吸头、容器和化学药品的库存减少，几乎阻碍了工作流程的每个环节。

在公共卫生实验室协会（Association of Public Health Laboratories）最近调查的72家机构中，超过20％的机构表示，他们将在一周内用完至少一类检测所需的实验室用品。大约有超过20%的机构称，他们无法满足当前的检测需求。

Just weeks after resolving shortages in swabs, researchers are struggling to find the chemicals and plastic pieces they need to carry out coronavirus tests in the lab — leading to long waiting times.

Labs across the country are facing backlogs in coronavirus testing thanks in part to a shortage of tiny pieces of tapered plastic.
Researchers need these little disposables, called pipette tips, to quickly and precisely move liquid between vials as they process the tests.

Pipette tips aren’t the only laboratory items in short supply. Dwindling stocks of machines, containers and chemicals needed to extract or amplify the coronavirus’s genetic material have clogged almost every point along the testing workflow.

More than 20 percent of the 72 institutions recently surveyed by the Association of Public Health Laboratories have said they will run out of at least one item required to do their tests within a week. About as many said they were unable to meet current testing needs.  source
