What do the numbers after the antibiotic mean in a urine c&s?

10 doctors weighed in across 4 answers

MIC: This number is called the minimum inhibitory concentration (or mic). It means the lowest concentration of antibiotic that inhibits the growth of the organism. In general, the lower the mic, the more sensitive the organism is to the antibiotic. There are other factors that go into choosing an antibiotic however, so choosing the antibiotic with the lowest mic is not always best.

Probably sensitivity: The numbers probably reflect the effective concentration of antibiotic for the particular organism.
