What causes contamination in urine?

Contamination in urine can occur due to various factors, including improper collection techniques, exposure to external substances, and the presence of bacteria from the skin or genital area. Additionally, if the urine sample is not collected in a sterile container or if it is not handled and stored correctly, the risk of contamination increases. This can lead to inaccurate test results, affecting diagnoses and treatment decisions. Proper hygiene and careful collection methods are essential to minimize contamination.
