Ezy MIC™ strip is useful for quantitative determination of susceptibility of bacteria to antibacterial agents. The system comprises of a predefined quantitative gradient which is used to determine the Minimum Inhibitory Concentration (MIC) in mcg/ml of different antimicrobial agents against microorganisms as tested on appropriate agar media, following overnight incubation. Meropenem Ezy MIC™ Strip is a thin, inert and porous paper strip coated with Meropenem on a single paper strip in a concentration gradient manner, capable of showing MICs in the range of 0.002 mcg/ml to 32 mcg/ml, on testing against the test organism. Both sides of the strip are likewise printed with the MIC reading scale in μg/ml and the three letter symbol “MRP” printed on the top of the strip helps in easy identification of the antibiotic.
