Midstream “Clean-Catch” Urine Specimen Midstream “clean-catch” urine collection is the most common method of obtaining urine specimens from adults, particularly men. This method allows a specimen, which is not contaminated from external sources to be obtained without catheterization. It is important to follow the “clean-catch” protocol to have accurate results from an uncontaminated sample. Purpose The clean-catch urine method is used to prevent germs from the penis or vagina from getting into a urine sample. It is a method of collecting a urine sample for various tests, including urinalysis, cytology, and urine culture. Supplies and Equipment Sterile specimen cup Zephiran, a soap solution, or three antiseptic towelettes Three cotton balls (to use with zephiran or soap solution) Laboratory request form Preparation Explain to the patient that this kind of urine collection involves first voiding approximately one half of the urine into the toilet, urinal, or bedpan, then collecting a portion of midstream urine in a sterile container and allowing the rest to be pass into the toilet. Discuss that this is done to detect the presence or absence of infecting organisms and, therefore, must be free from contaminating matter that may be present on the external genital areas. Procedure For female patients: 1 Wash hands with soap and water. 2 Instruct the patient to clean perineal area with towelettes or cotton balls.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
