keskisuihkunäytettä

Keskisuihkunäyte refers to a midstream urine sample. This method of collection is standard for most urine tests, including urinalysis and urine culture. The purpose of collecting a midstream sample is to obtain urine that is less contaminated by bacteria or cells from the external genital area.

To collect a midstream urine sample, the individual first cleans the genital area. Then, they begin urinating into the toilet. After the initial flow of urine has passed, the collection container is positioned to catch the urine midstream. Finally, the individual finishes urinating into the toilet. This technique helps ensure the sample is representative of what is being produced by the urinary tract, rather than potentially influenced by external factors. Proper collection is crucial for accurate diagnostic results, as contamination can lead to false positives or negatives. Healthcare providers will often provide specific instructions on how to collect the sample correctly.
