Drug & Alcohol Screening
A drug test is only as reliable as the process behind it.
About Drug & Alcohol Screening
A drug test is not just a medical check. It is a legally sensitive process. The result is only as reliable as how the test is carried out. Without proper controls, results can be legally challenged, compromised by contamination or tampering, or misinterpreted without proper confirmation.
At Trinity Medical, we provide Drug & Alcohol screening both in-clinic and on-site to help your organisation maintain safety and meet regulatory requirements. Our programme is led by certified Medical Review Officers (MROs) who are members of AAMRO, and every step is controlled to ensure accuracy and compliance.
Common Questions We Resolve
My company already conducted a drug test. How do we know the results are reliable and properly handled?
Can our drug test results withstand disputes, or legal scrutiny?

Even a single procedural error can invalidate the entire test.
The most common reason drug tests are rejected in court is a break in the chain of custody. In drug and alcohol screening, how the test is conducted is just as important as the result itself. We make sure every test is done properly so your results are accurate, compliant, and defensible.
