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

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.

Sensitivity patterns: The less the number more effective is the antibiotic.

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

MIC: The numbers on any culture are the minimum inhibitory concentration. In simple english, can the abx kill the bug and if can be used. Try this link https://en.wikipedia.org/wiki/Minimum_inhibitory_concentration. Hope this helps.

How do doctors determine antibiotic dosages for babies?

Dr. Anatoly Belilovsky
Pediatrics 35 years experience
Per kilo body weight: Most antibiotics have dosages by milligrams per kilo body weight per day; amoxicillin, for example, is 40-100 mg/kg/day, so an 11-pound (5-kilo) baby would get up to 500 mg per day, usually in 2 doses, so that's 250 mg twice a day, maximum.

Most often: food!: The first thing that comes to mind, of course, is diabetes. But for many pregnant women, kidney function changes. Often, the same morning a pregnant women drinks a big glass of orange juice, we'll find sugar in her urine sample. However, that is not to say we ignore the findings -- all pregnant women do get tested for gestational diabetes between 24 and 28 weeks.
