test strips

Test strips are small, single-use strips coated with chemicals that react with specific substances in a sample, such as urine, blood, or water. When the strip is dipped into the sample, the chemicals change color based on the concentration of the target substance. By comparing the color change to a reference chart, you can determine levels of substances like glucose, pH, or toxins. They’re commonly used for quick diagnostic or monitoring purposes, providing a simple and reliable way to assess health or environmental conditions without complex lab equipment.
