What is needed to collect a sterile urine specimen?

To collect a sterile urine specimen, a urinometer is required as it is specifically designed for measuring the specific gravity of urine, which can provide valuable diagnostic information. However, the collection of a sterile urine specimen primarily involves using sterile containers and equipment to prevent any contamination. While a urinometer may be a part of the analysis process, for the actual collection, the emphasis is on maintaining sterility, which may also involve obtaining a midstream catch or using a catheter depending on the specific circumstances.

The other items listed serve different functions. A needle and syringe could be used for collecting certain types of samples but is not typically required for urine collection. A glucose meter is used for measuring blood glucose levels and would not be applicable for urine specimen collection. A tourniquet is commonly used in blood draws to engorge veins but is not relevant in the context of urine collection. Selecting the right equipment and techniques is crucial when dealing with sterile samples, ensuring accuracy in testing and results.
