For the detection of a possible urinary tract infection and the causative microorganism, a midstream clean-catch urine specimen is typically recommended. This type of specimen is less likely to be contaminated by bacteria from the skin or external genitalia, and therefore provides a more accurate representation of what is present in the bladder and urinary tract.
To collect a midstream clean-catch urine specimen, the patient should first wash their hands and genital area with soap and water. They should then urinate a small amount into the toilet to clear any bacteria from the urethra. Next, the patient should start to urinate into a sterile container, which has been provided by the healthcare provider. Midway through the stream, they should hold the container in place and collect a sample of urine. They should then finish urinating into the toilet.
As mentioned in the previous answer, to collect a midstream clean-catch urine specimen, the patient should urinate a small amount into the toilet to clear any bacteria from the urethra. Next, they should start to urinate into a sterile container, which has been provided by the healthcare provider. Midway through the stream, they should hold the container in place and collect a sample of urine. They should then finish urinating into the toilet. The container should then be securely capped and labeled with the patient's name and other relevant information, and sent to the laboratory for analysis.
