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.

[ We claim:] [1.]1. A sample testing apparatus comprising:a solid body having a portion thereof defining a well for containing a reagent and a test sample to be tested; anda membrane affixed to said solid body in a manner to cover said well and thereby close said well off from the environment and thereby convert said well into a closed reaction chamber;wherein said membrane provides a non-venting, but high oxygen transmissible and permeable barrier between said reagent and fluid sample in said well and an atmosphere external of said closed reaction chamber, and further provides a liquid and solid-phase impermeable barrier for said closed reaction chamber preventing solid or liquid-borne contaminants from entering said closed reaction chamber,and wherein said membrane has an oxygen permeability relative value at 1 mils thickness substantially greater than 1,500 cc/100 in.sup.2 /24 hours at 25 degrees C.
