Abstract
A test sample card has a well formed in the card body for receiving a fluid sample containing a microbiological agent or microorganism and a reagent. The test sample card has a membrane in the form of a tape covering the sample well to form a closed reaction chamber of the fluid sample and reagent and provide a barrier between the fluid sample and the atmosphere. The tape is made from polymethylpentene. The high oxygen permeable and transmissible characteristics of the tape promotes a reaction between the reagent and the microorganism. The increased growth rate exhibited by the microorganism, as compared to prior art tapes, substantially reduces the time needed to complete the test detection such as using transmittance optical analysis, for example confirm of the identity of the microbiological agent or the susceptibility of the microorganism to antibiotic agents.
