Colorimetric Tests

Colorimetric tests are diagnostic methods that identify or analyze substances based on color changes when a reagent interacts with the target compound. When a sample reacts with a specific chemical indicator, it produces a visible color shift proportional to the substance’s presence or concentration. These tests are quick, easy to interpret, and commonly used in clinical labs, environmental analysis, and food testing to detect chemicals, toxins, or biological markers without requiring complex equipment. The resulting color change acts as a visual cue, aiding in rapid decision-making.
