Minimizing contamination in urine samples relies on using aseptic technique and a midstream collection. Clean-catch midstream with a sterile container helps ensure the specimen reflects urine from the bladder rather than skin or periurethral flora. The initial part of the urine flow can carry contaminants, so starting to urinate and then collecting the middle portion reduces those contaminants, and using a sterile container prevents introducing new organisms. If urine is collected from a diaper, in a non-sterile container, or without cleansing the area, the sample is much more likely to be contaminated, which can lead to inaccurate culture results. Proper steps include washing hands, cleansing the genital area, starting the urine stream, collecting the midstream portion in a sterile container, and securing the cap promptly.
