How long does it take to get the results of urine culture drug sensitivity? It may vary from hospital to hospital, but the results are usually available in 3-5 days. For patients with recurrent urinary tract infections, the doctor will recommend a clean urine culture, which is a relatively clean urine taken from the middle section of the urine and used for bacteriological culture tests. However, if some patients have previously taken antibiotics, the probability of culturing the bacteria is greatly reduced. If the culture comes back with targeted bacteria or a more sensitive antibiotic, the doctor can then choose a more symptomatic antibiotic to treat the infection.
