A culture is done to find out what kind of organism (usually a bacteria) is causing an illness or infection.
A sensitivity test checks to see what kind of medicine, such as an antibiotic, will work best to treat the illness or infection.
A culture is done by collecting a sample of fluid or tissue and then rubbing the sample onto a special plate with prepared gelatin (culture). If there are bacteria in the sample, they will grow in the culture, usually within 2 days.
A culture and sensitivity test may be done on many different body fluids, such as urine, mucus, blood, pus, saliva, breast milk, spinal fluid, or discharge from the vagina or penis.
