When it comes to preventing sample tampering in workplace drug testing, Integrity Sampling has a secret weapon. But it’s not a gadget, trick, or anything underhanded. The secret is simply saliva drug testing. It’s accurate, fast, and much harder to cheat than traditional urine testing. Employers like it for its reliability and employees appreciate the convenience. The only people not happy are those hoping to cheat the system!
Tampering of samples in drug testing – whether it’s in the workplace, sport or another environment – isn’t overly common but it does happen. And in the workplace, it can undermine safety and fairness. In the past, people have tried to dilute urine, substitute someone else’s sample, or even use chemicals to hide drug use.
In this blog, we’ll explore how Integrity Sampling prevents tampering, why saliva testing is a superior option, and what businesses can do to ensure a fair and trustworthy drug testing program.
What is Sample Tampering?
Sample tampering occurs when a person tries to alter or interfere with their specimen to avoid a positive test result. In workplace drug testing, this can happen in several ways, depending on the type of test.
For example, in urine drug testing, people have attempted to:
- Dilute the sample by drinking excessive amounts of water beforehand or even adding water directly to the container.
- Substitute the sample with “clean” urine from another person.
- Mask the sample by adding substances or chemicals designed to hide the presence of drugs.
- Use commercial products like detox drinks or powders that claim to flush the body before testing.
These attempts at cheating are well documented. In fact, entire industries exist that promote ways to get around urine drug tests. While many of these don’t work (sorry, those detox capsules available online will drain your wallet but nothing else!) the concern shouldn’t be dismissed. Because, without the right procedures in place, it is possible for testing results to be compromised.
Preventing Sample Tampering Requires Strict Protocols
At Integrity Sampling, the prevention of sample tampering is one of our highest priorities. We achieve this through standardised procedures and careful oversight.
Here’s how we protect the integrity of the process, for both saliva or urine testing:
- Supervised collection – Our consultants monitor every step of the collection process to make sure samples are provided correctly and securely.
- Secure containers – Specimens are placed in containers that are designed to prevent leaks, spills, or substitution.
- Tamper-evident seals – Once collected, samples are sealed with tamper-proof systems so that any attempt to interfere is immediately obvious.
- Detailed documentation – Every step of the process is recorded, from collection through to laboratory delivery if required. This creates a clear chain of custody and ensures accountability.
These measures mean that businesses can rely on the results. They protect both the company and the employee by ensuring the testing process is fair and transparent.
Why Saliva Drug Testing is Harder to Cheat
While urine drug testing has traditionally been the most common method of workplace drug testing, using saliva samples is becoming increasingly popular. While it’s certainly not the only reason, one of the keys is saliva testing is far harder to tamper with.
With saliva drug testing:
- Collection is observed directly and does not need to be done privately (e.g. in a restroom) reducing the chance of substitution.
- The sample is provided immediately, without the need for special facilities.
- There is no opportunity to add chemicals, water, or other substances to alter the results.
This makes saliva testing a strong choice for businesses that want accurate results and minimal opportunity for cheating.
Real-World Examples of Urine Test Tampering
To understand the advantage of saliva testing, it’s worth looking at some real-world examples of how urine drug tests have been tampered with in the past. These include:
- Synthetic urine kits, which are sold online and designed to be smuggled into the collection area.
- Hidden containers, such as small bottles or pouches strapped to the body and filled with another person’s urine.
- Powders and tablets, marketed as “cleansers,” which claim to remove traces of drugs from the system before the test. Spoiler alert: These don’t work!
- Adulteration methods, like adding bleach or vinegar to the sample to try to distort results.
These methods highlight why urine testing is more vulnerable to tampering. While collection protocols reduce the risk, the opportunity to cheat is still higher compared to saliva testing.
Protecting Fairness in the Workplace
The prevention of sample tampering is not just about protecting the accuracy of test results. It’s also about protecting fairness in the workplace. Employees who are doing the right thing deserve to know that the process is equal for everyone.
When tampering is prevented, the results reflect the true picture. This helps businesses manage risks more effectively, maintain safety, and support a culture of trust.
