Tips on Faint Lines and Drugs of Abuse Tests
What does a Faint Line mean?
- If the Test Line for one particular drugs of abuse immunoassay is very faint and much fainter than the Control Line, it is called Faint Line. There is no meaning attributed to line color intensity or width. As long as a colored band is observed in the appropriate Test Region (T), no matter how faint, the result should be interpreted as Negative.
What may cause a Faint Line?
- The Human Urine Metabolome: As a biological waste material, urine typically contains metabolic breakdown products from a wide range of foods, drinks, drugs, environmental contaminants, endogenous waste metabolites and bacterial by- products. Many of these compounds are poorly characterized and poorly understood. Certain compounds may cause faint line for drugs of abuse immunoassay.
- Cross Reactivity: Immunoassay testing is the binding of a target analyte or drug molecule to its specific antibody. Cross-reactivity is when an analyte or drug molecule that is very similar to the target analyte or drug molecule binds to the specific antibody which may cause faint line or false positive result. Common potential interfering substances are listed in the package insert. However it is not possible to test every compound. Professional judgment should be exercised with any drug test result, particularly when the preliminary result is positive. A more specific alternative analytical method should be used to obtain a confirmed result. Gas Chromatography/Mass Spectrometry (GC/MS) or Liquid Chromatography/Tandem Mass Spectrometry (LC/MS-MS) are preferred confirmatory methods.
- Assay to Assay Difference: Faint lines on drug tests are very common. Marijuana (THC) immunoassay is more likely to have faint lines because of the components of Marijuana itself as well as more natural substances that interact with THC.
Follow these simple precautions to reduce Faint Lines:
- Follow the test procedure instruction listed in the package insert.
- Do not use the test kit beyond expiration date.
- Do not use the test kit if the pouch is punctured or not well sealed.
- Store the test kit at 4°C-30°C (39°F-86°F) in the sealed pouch up to the expiration date.
- Keep the test kit away from direct sunlight, moisture and heat.
- Do not freeze the test kit.
- Collect donor medications and supplements consumption information for further investigation when needed.
