What is the primary use of a specimen cup?

The primary use of a specimen cup is to gather urine for testing. This type of cup is specifically designed to safely collect and transport urine samples to a laboratory for various tests, including those for infections, substances, or other health-related analyses. The design of a specimen cup typically includes features that ensure the sample remains uncontaminated, preserves its integrity, and allows for clear labeling and easy handling.

The other options refer to different uses that do not align with the primary function of a specimen cup. For instance, holding liquid medication generally involves a different type of container designed for safety and dosing accuracy. Measuring blood pressure requires specific medical instruments, typically a sphygmomanometer, which are not related to specimen collection. Collecting saliva samples is often done using specialized kits or containers specifically meant for that purpose. Each of these functions requires distinct tools or procedures tailored to the nature of the sample being collected or measured.
