Collect the required biological sample (e.g., blood drop, urine). Apply the sample to the designated area of the test strip, ensuring adequate saturation without over-application. Wait for the specified reaction time, then read the result visually or with a compatible meter. Dispose of the used strip properly.

The test strip contains specific chemical reagents immobilized on a matrix. When a biological sample is applied, the analyte in the sample reacts with these reagents, leading to a chemical reaction (e.g., enzymatic, immunological) that produces a detectable signal. This signal is often a color change proportional to the analyte concentration, which can be visually interpreted or read by a specialized meter.

• •Do not use expired test strips.
• •Do not use if the packaging is damaged or tampered with.
• •Do not use if the strip itself appears discolored or damaged.

Store at room temperature (15-30°C), in a dry place, away from direct sunlight and moisture. Keep in the original container with the cap tightly closed. Do not refrigerate or freeze.

Not applicable; test strips are not ingestible and do not have an 'overdose' potential in the medical sense. Misuse may lead to inaccurate results.

Safe for use during pregnancy and lactation, as it is an external diagnostic device and has no systemic effect on the body. Pregnancy tests (hCG strips) are specifically designed for use during pregnancy.
