This Kit is designed to quickly and easily determine if a colony (CFU) growing on your R-CARD^® ECC or on your chromogenic petri dishes that does not match the commonly expected results (too small/large, questionable color—too green, red, etc.) is or is not E. coli or Coliform.

If there is a colored growth spot (teal/green on Card #1) and a colored growth spot (pink) on Card #2) , the test colony is verified as E. coli. If only one or no spots show color, the test colony is not E. coli. If Card #1 has no colored teal/green growth, but Card #2 shows pink/red growth, the tested colony is verified as a Coliform.
