What are the advantages of using in-house organisms in WET tests?
There are several. First, organisms that are cultured and used in-house have not undergone the stress of shipment. Factors such as fluctuating temperatures, harsh physical movements, photoperiod alterations, and the build up of metabolic wastes during transportation stress the organisms and, depending on their severity, alter organism sensitivity and health. Secondly, in-house organisms are immediately available. This is advantageous for receiving samples on short notice and also because laboratory analysts can evaluate the condition of a particular batch of organisms with recourse. Unsatisfactory organisms can be disposed of and replaced with a better batch. [ Back to top.
