test strip

A **test strip** is a small, narrow piece of material used for diagnostic or measurement purposes. Commonly found in medical, chemical, and environmental testing, test strips are designed to react with or detect specific substances, offering quick and easy results. For example, in healthcare, test strips can check glucose levels in blood or detect the presence of certain chemicals in urine. In other industries, they help monitor water quality, pH levels, or contamination. Test strips provide a convenient and cost-effective way to conduct preliminary testing without the need for complex equipment.
