How to Dispute a False Positive Drug Test: A Comprehensive Guide

Receiving a positive drug test result can be a life-altering event. It can jeopardize your job, your reputation, and even your personal relationships. But what happens when you know you haven’t used drugs? A false positive drug test can occur for various reasons, and understanding your rights and how to challenge such a result is crucial. This comprehensive guide will walk you through the steps you need to take to dispute a false positive drug test effectively.

Understanding False Positives

Before diving into the dispute process, it’s important to understand what can cause a false positive. Common reasons include:

• Cross-reactivity: Certain over-the-counter and prescription medications can trigger a positive result. For example, some decongestants can mimic amphetamines.
• Food and Beverages: In rare cases, consuming certain foods or beverages (like poppy seeds) can lead to a positive test for opiates.
• Laboratory Errors: Mistakes during sample collection, handling, or testing can lead to inaccurate results.
• Passive Exposure: In rare cases, prolonged exposure to second-hand smoke might cause a positive test for marijuana, though this is controversial and unlikely with modern testing methods.
• Medical Conditions: Certain medical conditions like kidney problems may lead to incorrect test readings.
• Contaminated Samples: Accidental sample contamination during collection or processing is a rare, but possible, source of errors.

Step-by-Step Guide to Disputing a False Positive

If you believe your drug test result is inaccurate, here’s a detailed step-by-step guide on how to dispute it:

1. Remain Calm and Collect Information

Your initial reaction might be panic or frustration, but it’s crucial to stay calm and approach the situation methodically. Here’s what you should do first:

• Document Everything: Keep meticulous records of everything related to the drug test, including the date, time, location, the testing company, and the person who administered the test. Note the type of test performed (urine, hair, blood, saliva).
• Obtain a Copy of the Results: Request a copy of your official drug test results, preferably in writing. Don’t just rely on what someone tells you.
• Review the Results Carefully: Look at the specific substances that tested positive, the cut-off levels, and any comments on the report. Understanding this information is crucial for building your case.
• Gather Medication Information: Make a list of all medications, supplements, and over-the-counter drugs you have taken in the days and weeks leading up to the test. Note the dosage and the prescription information if applicable. This is a crucial piece of evidence, as many medicines can lead to false positives.
• Document any relevant food or beverage consumption: If you recall consuming food items that have been known to cause false positives such as poppy seeds, document that information.
• Note Any Possible Exposure: Think about potential sources of exposure such as second-hand smoke or accidental contact with drug-related substances, even though these causes are rare.
• Identify Witnesses (If applicable): If possible, see if you have witnesses who can verify your drug-free status.

2. Understand Your Employer’s or Testing Facility’s Policies

Before proceeding, it’s crucial to understand the policies and procedures of your employer or the testing facility involved. This includes:

• Review Your Company’s Drug Testing Policy: If this is a workplace drug test, understand your employer’s specific policy about disputing results. Are there timelines? Specific procedures to follow?
• Check the Testing Facility’s Procedures: Review the lab’s procedures for handling disputes. Most reputable labs have specific protocols in place.
• Understand the Consequences: What are the consequences of failing a drug test according to company policies? This helps you grasp the severity of the situation and helps you to determine the urgency of the dispute.
• Identify contact persons: Identify the specific individuals you will need to contact at your workplace and the testing laboratory.

3. Request a Re-Test

The most important step is to request a re-test. Here’s how to go about it:

• Contact Your Employer or the Testing Facility Immediately: Notify them of your belief that the test result is incorrect. Do this as soon as possible, preferably in writing, but also follow up with a phone call.
• Request a Second Test of the Original Sample: This is called a confirmation or re-test. Ask if a second analysis will be conducted using a more specific and sensitive method (such as Gas Chromatography-Mass Spectrometry – GC-MS), which can help pinpoint the actual cause of a positive result. Many initial screening tests are less specific and may yield false positives.
• Request Chain of Custody Documentation: Request to see the Chain of Custody documentation, this will track who handled the specimen to ensure there were no breaks in the chain.
• Do not delay: There are often time limits on requesting a retest. Ensure you understand those deadlines and move quickly to request the retest.
• Inquire about the costs: Ask who is responsible for the costs of a retest. Many labs will conduct a second, more specific test to confirm initial positives.
• Keep track of the request: Always document the time and date of your requests and record the person you speak to.

4. Provide Supporting Evidence

While waiting for the re-test results, collect any supporting evidence that strengthens your claim. This includes:

• Medication List: Provide a detailed list of all medications you are taking, along with copies of your prescriptions. Include dosages and the names of the prescribing doctors.
• Doctor’s Note: If you have a medical condition that could have caused a false positive, obtain a note from your doctor. This can be extremely helpful.
• Witness Statements: If possible, obtain written statements from people who can vouch for your drug-free lifestyle.
• Food Log: If you suspect that food consumption could be the reason behind the result, a detailed food log leading up to the test might be useful.
• Relevant receipts and packaging: If you have any receipts for the medications you are taking, keep those handy. Also keep the packaging for any over-the-counter medicines or supplements you have been taking.
• Keep all documents organized: Make copies of all supporting documents and organize them systematically.

5. Communicate and Follow Up

Effective communication and persistence are key throughout the dispute process:

• Maintain Clear Communication: Clearly state your concerns about the accuracy of the initial test result.
• Follow Up Regularly: Don’t be afraid to follow up on the progress of your re-test and your dispute. Keep a log of all your communications (date, time, and who you spoke with).
• Be polite but firm: It is important to be firm and assertive that you did not take the substance in question. However, you should always be polite and professional in your communication.
• Document all communication: Whether verbal or written, keep records of every communication.
• Contact the relevant HR personnel: If this is a workplace related issue, contact the relevant HR personnel to make sure they are aware of the dispute.

6. Seek Expert Advice If Needed

If you feel overwhelmed or you’re facing significant resistance, don’t hesitate to seek expert advice. This could be:

• Toxicology Expert: A toxicologist can review your results and medication list and provide an opinion on the likelihood of a false positive.
• Employment Lawyer: If the false positive is affecting your employment, an employment lawyer can help you understand your legal rights.
• Union Representatives: If you’re part of a union, seek guidance and support from a union representative.
• Consumer advocacy groups: They can provide advice and support on your rights.

7. Consider Further Legal Action (If necessary)

If your efforts to resolve the issue through the above steps have been unsuccessful, you might need to consider further legal action. This could involve:

• Filing a Formal Complaint: You can file a formal complaint with the testing facility’s governing body or licensing agency.
• Contacting the Department of Transportation (if applicable): If your test is related to transportation industry standards, contact the relevant department of transportation.
• Legal Action: If the false positive caused significant harm to your reputation, career, or mental health, you might have grounds to sue for defamation or negligence. This should be a last resort, and only after consulting an attorney.
• Consult with an attorney: A qualified attorney can assess your situation and advice on your legal options.

Tips for Preventing False Positives

While not always avoidable, you can take some steps to minimize the risk of false positive drug tests:

• Be Transparent: Always inform your employer or the testing facility about any medications you’re taking before taking the test.
• Avoid Risky Substances: Be mindful of what you consume, avoiding poppy seeds and certain over-the-counter medications that may cause false positives.
• Stay Hydrated: Drink sufficient water before testing to ensure a good sample.
• Verify Testing Practices: If you are having to take a drug test that you organized, verify the reputation of the testing facility and ensure they have robust procedures for handling and analyzing specimens.
• Maintain Overall Health: A healthy lifestyle can reduce the likelihood of certain medical conditions that may cause false positives.
