What Is an Accidental Dilution Drug Test?

An accidental dilution drug test occurs when a urine sample provided for drug testing is diluted unintentionally, often due to a variety of reasons such as excessive fluid intake, medications, or medical conditions. Accidental dilution can cause the concentration of drugs or their metabolites to fall below the detection threshold, resulting in a false-negative result.

While an accidental dilution drug test may not necessarily indicate drug use, it can be viewed as a failed test, and the individual may be required to provide another sample.

How Do I Make Sure My Drug Test Is Not Diluted?

To ensure that your drug test is not diluted, here are some steps you can take:

  1. Drink fluids in moderation: Drinking too much water or other fluids before the test can dilute your urine sample. It is recommended to drink no more than 8 to 16 ounces of fluids in the hour before the test.
  2. Avoid diuretics: Diuretics, such as coffee or tea, can increase urination and potentially dilute your urine sample. Avoid consuming these beverages before the test.
  3. Do not tamper with the sample: Do not add anything to your urine sample, such as water or other substances, as this can be detected by the testing lab and lead to a failed test.
  4. Follow testing instructions: Follow the testing instructions carefully. If you are unsure of the instructions, ask the test administrator for clarification.
  5. Provide an adequate sample: Providing an adequate sample is essential to ensure that the test results are accurate. Make sure to provide the required amount of urine in the collection cup as per the testing instructions.
  6. Be honest about medications: If you are taking any prescription or over-the-counter medications that may affect the test results, inform the test administrator beforehand.
  7. Avoid strenuous exercise: Strenuous exercise can break down muscle tissue and release creatinine into the bloodstream, which can make the urine sample appear less diluted. Avoid excessive exercise before the test.

By following these steps, you can help ensure that your drug test results are accurate and not affected by accidental dilution.

Can I Dispute the Result If I Believe the Sample Was Unintentionally Diluted?

If you believe that your drug test result was affected by an unintentionally diluted sample, you may have the option to dispute the result. However, the specific procedures for disputing a drug test result can vary depending on the drug testing policy in place and the specific circumstances of the test. Here are some general steps you can take to dispute a diluted drug test result:

  1. Inform the testing administrator: If you suspect that your sample was diluted unintentionally, inform the testing administrator immediately. They may be able to provide additional guidance or retest your sample.
  2. Provide additional samples: If you are required to provide additional samples, make sure to follow the testing instructions carefully and provide an adequate sample to avoid dilution.
  3. Seek medical advice: If you have a medical condition that may affect the test results, consult with a medical professional and provide documentation to support your claim.
  4. Request a retest: If you believe that the test result is inaccurate, you may request a retest. Some drug testing policies may require additional testing to confirm the result.

It is important to note that disputing a drug test result can be a complex process, and the outcome may vary depending on the specific drug testing policy in place and the circumstances of the test.
