cfu ml escherichia coli value
The ELIEDA was positive for all 71 of the urine specimens in which E. coli had been identified at a bacterial concentration higher than 105 CFU/mL. However, the ELIEDA assay gave negative results for the 5 urine specimens with E. coli concentrations ranging from 1.2 x 104 to 5 x 104 CFU/mL. These values below 105 CFU/mL are conventionally considered to be nonsignificant from a clinical standpoint (10, 24).
