How to Store and Handle Test Strips Correctly?

Test strips serve a variety of purposes, from substance abuse prevention to healthcare diagnostics. Proper handling and storage of test strips are crucial to ensure reliable and accurate results. In this article, you’ll learn how to maintain the integrity of your test strips with proper handling and storage.

Understanding Test Strips

Test strips can be small, disposable devices that are designed to give quick and accurate results for specific applications. The drug test kit is widely used in medical diagnostics and drug testing. Even at home, they can be used to test for diabetes, pregnancy, or other conditions. These strips have reagents (chemicals) that react with a target substance within the sample. The result is a visible change in color or signal.

Types Test Strips

  • Medical Strips: These strips are commonly used in healthcare to test different parameters like blood sugar, cholesterol, or urinary signs of infection and disease.
  • Testing strips for Fentanyl: These test strips are specifically designed to detect Fentanyl, a potent synthetic opioid. It is important to use these test strips in harm prevention efforts, especially when preventing overdose deaths.
  • COVID – Test Strips:Covid testing kit is vital in the detection of SARS-CoV-2 (the virus responsible for COVID-19). Both at-home and clinic tests are performed to detect infection.

Proper Storage Guidelines

To ensure reliability and accuracy, test strip storage must be done correctly. Here are a few essential guidelines on how to store test strips.

  • Storage temperature: Use the temperature recommended by your manufacturer. Extreme heat or low temperatures can compromise the stability of the chemicals on the strip. When storing test strips inside a hot vehicle or in a cold environment, results may need to be more accurate.
  • Humidity: Protect strips from excessive moisture. Humid conditions may lead to a degradation of the chemical strip.
  • Sealing: Wait to open the original package until you want to use the strips. This will prevent them from being exposed externally to elements that may compromise their integrity.
  • Light: Store the test strips away directly from sunlight or strong artificial lighting. The exposure to light will alter the chemical reactions.

Proper Handling Practices

You can also affect the accuracy of test strips by handling them. Here are a few important handling tips:

  • Wash Hands Before Handling Test Strips: Your hands should be clean and dry. Contaminants that are on your fingers may interfere with the results.
  • Read Instructions: Familiarize yourselves with the manufacturer’s directions for using test strips. Each type can have different handling requirements.
  • Do Not Cross-Contaminate:¬†Always use a clean, disposable sample collection tool when collecting a specimen for testing. Cross-contamination by previous samples could lead to inaccurate testing results.
  • Read Timing Guidelines: Some test strips require that the results be read within a specified time frame. Please follow the suggested timing to ensure correct interpretation.


Storage and handling of test strips are important practices that cannot be overlooked. You should always follow the instructions of the manufacturer and maintain the integrity and quality of the test strips. This is true whether you’re using fentanyl test kits or medical test strips.

By following the guidelines, you will contribute to the effectiveness and efficiency of diagnostic tools. This includes harm reduction programs, prevention of substance abuse, and public safety measures. As the accuracy of results can have an impact on health and wellness, test strips must be stored and handled correctly.
