How Reagent Strips Work

Reagent strips utilize chemical reactions to produce color changes, which correspond to the concentration of specific substances in the sample being tested. The process typically involves these steps:

1. Sample Collection: A sample of urine (or another fluid) is collected in clean conditions.
2. Dipping the Strip: The reagent strip is dipped into the sample to allow the chemicals to interact with the fluid.
3. Waiting Period: After a brief waiting period, the strip is compared against a color chart.
4. Result Interpretation: The resulting color changes indicate the concentration of various substances, enabling healthcare professionals to assess the patient’s health status.

Common Uses of Reagent Strips

Reagent strips can test for a variety of substances, including:

• Glucose: To screen for diabetes.
• Ketones: To monitor conditions like diabetic ketoacidosis.
• Protein: To detect kidney issues.
• pH Levels: To assess urinary health.
• Nitrites: To identify urinary tract infections.
