What an Inconclusive Drug Test Means and Your Next Steps

An inconclusive drug test can be a confusing and stressful experience, whether for a job application, an employer-mandated screening, or a legal requirement. It's a result that doesn't fall into the simple categories of "positive" or "negative." 

Instead, it means the sample could not be conclusively tested, leaving the result uncertain. Understanding what an inconclusive drug test result means, what can cause it, and what steps to take next is essential to handling the situation effectively.

What an Inconclusive Drug Test Means

An inconclusive drug test is not a failed test. It indicates that the lab or testing device was unable to complete the analysis and determine the presence or absence of specific drug metabolites. This can occur for various reasons, and while some are benign, others may be viewed with suspicion by the requesting party, such as a potential employer or a court. The most common reasons for an inconclusive result include:

Diluted Sample

This is the most frequent cause. It occurs when a urine sample has a lower-than-normal concentration of creatinine, a waste product that is consistently excreted in the body. This often happens if an individual drinks a large amount of water or other liquids shortly before the test. A diluted sample is not a positive result for drugs, but it can be seen as an attempt to flush the system and mask drug use.

Adulterated Sample

Adulteration means the sample has been tampered with by adding a foreign substance to it. This can range from household chemicals like bleach to commercial products specifically designed to "clean" a drug test. However, labs test for common adulterants too, and if one is detected, the sample is immediately considered invalid or inconclusive, which can lead to the same consequences as a positive result.

Abnormal pH Levels

The pH of a healthy urine sample falls within a specific range. If the pH is too acidic or too alkaline, it can interfere with the chemical reactions of the drug test. This can be due to a medical condition, but it is also a common method of tampering.

Medication and Health Conditions

Certain prescription medications, over-the-counter drugs, or even specific health conditions can affect the chemical composition of a urine sample. For example, some medications can cause a false positive, while others may simply interfere with the test's ability to provide a precise result.

Laboratory Error

While less common, human or technical error can sometimes be the cause. This can involve issues with the collection process, the chain of custody, which means how the sample is handled and tracked, or a faulty test kit.

Your Next Steps

An inconclusive drug test result is a call to action, requiring a swift and well-informed response. Here's a step-by-step guide on what you should do:

1. Contact the Medical Review Officer (MRO)

If the test is for a regulated purpose (such as a job or legal matter), a Medical Review Officer will be involved. The MRO is a licensed physician who reviews all drug test results, including inconclusive ones. They will often contact you directly to discuss the result. This is your opportunity to be transparent and provide any legitimate explanations for the inconclusive finding.

2. Be Honest and Provide Documentation

If you have a valid reason for the result, such as a prescription for a medication that could have interfered with the test or a medical condition that explains abnormal pH or dilution, be prepared to provide a doctor's note or other documentation. This is critical for establishing a legitimate medical explanation for the result.

3. Prepare for a Retest

In nearly all cases, an inconclusive drug test will lead to a retest. If the original issue was a diluted sample, attempting to do the same thing again will likely be seen as a refusal to test, which often carries the same weight as a positive result. For the retest, pay close attention to the instructions provided. If you are told to avoid drinking excessive liquids, follow that guidance.

4. Be Aware of a Change in Test Type

The organization or employer may require a different type of test for the retest, such as a hair follicle or saliva test. These tests are generally more challenging to dilute or adulterate.

5. Communicate with Your Employer/Organization

It's important to be proactive and transparent with the party that requested the test. An inconclusive result can raise suspicion, and open communication can help maintain trust. Keep them informed of the situation and the retesting process.

Your Trusted Partner in Drug Testing

While an inconclusive drug test is not a "fail," it is not a "pass" either. It places the burden on you to provide a legitimate explanation and to demonstrate compliance through a retest. By understanding the potential causes and taking the right steps, you can navigate this process and move towards a definitive and hopefully favorable outcome. Ignoring an inconclusive result or attempting to circumvent the retest will almost certainly lead to negative consequences.
