ABSTRACT:
The present disclosure relates to a testing tray for use in the conducting of a series of tests on a liquid specimen such as a blood or urine sample, with the results of the individual test being used to provide means for identification of a microorganism present in said specimens. The testing tray includes a plurality of test channels, which are of a generally U-shaped or reverse bend configuration, each channel including an entry portion and a testing portion comprised of one or more test chambers. The testing portions of the respective channels are closed by a transparent plastic sheet or strip which is affixed to the base in overlying relation to the various channels. The strip is sealed to the upper surface of the base intermediate the respective channels to effectively isolate one from the other, while leaving the entry portion of each channel open for the introduction of a liquid specimen therein. A pivotally connected cover member is provided which includes a section of absorbent material, which cover member may be closed to overlie the test channel entry portions. Further, the testing tray includes desiccant means to purge the test channel of undesired moisture during storage, prior to use of the tray.
