Urine samples are a common diagnostic tool healthcare providers use to evaluate health and detect various conditions. Urinalysis helps identify and manage issues like urinary tract infections, kidney disease, and diabetes. This test checks the appearance, concentration, and content of urine for important health indicators. Collecting a sample correctly, especially using the “clean catch” method, is important for accurate results and prevents contamination from skin bacteria.
Preparing for Your Sample
Before collection, prepare properly to ensure the sample’s integrity. Start by thoroughly washing your hands with soap and water, then dry them completely. Gather all necessary supplies, including the sterile urine collection cup and cleansing wipes. Review any specific instructions from your healthcare provider, as these may contain details tailored to your test. If possible, collect the sample when urine has been in your bladder for at least two to three hours.
The Clean Catch Method
The clean catch method aims to collect a urine specimen free from most external contaminants. Carefully open the sterile urine cup, ensuring you do not touch the inside of the cup or its lid. Place the lid face-up on a clean surface to prevent contamination. Begin to urinate a small amount into the toilet first. This initial stream helps flush away any bacteria present in the urethra.
After the first few seconds, without stopping the flow, quickly position the collection cup into the stream. Fill the cup until it is about half full, or to the level indicated by your provider. Avoid touching the inside rim or the tip of the cup with your hands or body during this step. Once enough urine is collected, remove the cup from the stream and finish urinating into the toilet.
Specific Guidance for Females
Collecting a clean-catch urine sample for females involves specific steps due to anatomical considerations. After washing your hands, sit comfortably on the toilet with your legs spread apart. With one hand, use your thumb and forefinger to spread the labia. Maintain this separation throughout the cleaning and collection process to prevent contamination.
Using the provided cleansing wipes, clean the area between your labia by wiping from front to back. Typically, one wipe is used for each side, and a third for the center over the urinary opening. Discard each wipe after a single use. If you are menstruating, inform your healthcare provider, as menstrual blood can affect test results. Some providers may suggest inserting a fresh tampon to minimize contamination, or rescheduling the test if not urgent.
Handling Your Sample After Collection
Once collected, securely cap the container immediately, taking care not to touch the inside of the lid or the cup. Label the container with your full name, the date, and the time of collection. This step helps maintain accurate identification throughout testing.
If the sample cannot be transported to the laboratory immediately, refrigerate it. Storing the sample at 2 to 8°C (35.6 to 46.4°F) helps prevent bacterial growth that could compromise test results.
A refrigerated urine sample is acceptable for testing for up to 24 to 48 hours. However, it is always recommended to deliver it to the clinic or lab as soon as possible to maintain its integrity.
