Urinkultur

Urinkultur is a laboratory test used to detect and identify bacteria or other microorganisms in a urine sample. It is a crucial diagnostic tool for identifying urinary tract infections (UTIs). The process involves collecting a sterile urine sample, typically from the midstream of urination, to minimize contamination from the skin. This sample is then sent to a laboratory where it is cultured on specialized media designed to promote the growth of bacteria.

After incubation, usually for 24 to 48 hours, laboratory technicians examine the culture for the presence of microbial growth. If bacteria are present, they are identified based on their appearance, staining characteristics, and biochemical tests. The number of bacteria, often quantified as colony-forming units per milliliter (CFU/mL), is also determined. A significant number of specific bacteria typically indicates an infection.

Further testing, known as sensitivity or susceptibility testing, is performed on the identified bacteria to determine which antibiotics are effective against them. This information is vital for healthcare providers to prescribe the most appropriate and effective antibiotic treatment for the patient's UTI, thereby minimizing the risk of treatment failure and the development of antibiotic resistance. Urinkultur is an essential component in the diagnosis and management of urinary tract infections.
