It would be dangerous to incubate (keep and grow) cultures at temperatures close to body temperature (37Â°C) because doing so might allow the growth of pathogens harmful to health. So the maximum temperature used in school and college labs is 25Â°C.
If there is no or little growth on the agar after 24 to 48 hours of incubation, the urine culture is considered negative for pathogens and the culture is complete. If there are one or more pathogens present, further testing is performed.ith a urine culture, a small sample of urine is placed on one or more agar plates (a thin layer of a nutrient media) and incubated at body temperature.
