What is a lab drug test?

A lab drug test is a process in which a laboratory analyses a biological sample—such as urine, blood, saliva, hair, or sweat—to detect the presence of drugs or their metabolites. These type of drug tests are commonly used for purposes such as employment screening, legal or court-related requirements, medical diagnostics, or substance use monitoring.

Common features of Lab Drug Tests:

  1. Accuracy: Lab-based testing is highly accurate and reliable, as samples undergo thorough analysis using advanced equipment like gas chromatography-mass spectrometry (GC-MS) or high-performance liquid chromatography (HPLC).
  2. Comprehensive Testing: Lab tests can detect a wide range of substances, including:Marijuana (THC), Cocaine, Amphetamines, Opiates, benzodiazepines and many more.
  3. Types of samples: lab drug tests in the UK are commonly done on urine, saliva and hair samples. They can also be done on blood and sweat.
  4. Detection Windows: The time during which drugs can be detected depends on the type of test, the drug, and individual factors like metabolism.

Typical uses of a laboratory drug test:

  • Pre-employment drug testing: Required by employers to ensure a drug-free workplace. May be used to confirm results obtained with on site drug tests.
  • Random or scheduled workplace drug testing: Used in workplaces, sports, or legal agreements. May be used to confirm results obtained with on site drug tests.
  • Medical purposes: To diagnose substance abuse or monitor compliance with prescriptions.
  • Rehabilitation programs: To track progress during treatment.

Process:

  1. Sample collection: A sample is taken under controlled conditions, ensuring privacy while preventing tampering.
  2. Transport to lab: The sample is securely sent to a certified lab.
  3. Analysis: Sophisticated methods are used to identify drug presence.
  4. Results: A detailed report is issued, usually within a few days of the sample being received by the lab.

Common names for laboratory drug tests in the UK

In the UK, laboratory drug tests are commonly referred to by a variety of names depending on the context and purpose of testing. These include:

  1. Laboratory Drug Screening – A general term for lab-based drug tests.
  2. Confirmatory Drug Testing – Refers to tests that confirm results from preliminary screenings.
  3. LC-MS/MS lab drug test-the new gold standard for lab drug testing
  4. GC-MS Testing (Gas Chromatography-Mass Spectrometry) – The old gold standard for detailed and accurate drug identification.
  5. Toxicology Screening – A broader term that includes testing for drugs, alcohol, and poisons.
  6. Urine Drug Confirmation Test – Specific to urine samples analysed in a laboratory setting.
  7. Workplace Laboratory Drug Test – Often used in corporate or occupational health contexts.
  8. Forensic Drug Analysis – Used in legal or criminal investigations.
  9. Chain of Custody Drug Testing – Refers to tests ensuring samples are handled securely, often for legal purposes.

These terms are widely recognised by healthcare professionals, workplaces, and legal entities across the UK. Organisations such as UK Drug Testing, AlphaBiolabs, and private clinics also offer these drug testing services.

What is a LC-MS/MS lab drug test?

An LC-MS/MS lab drug test is a highly sensitive and specific method for detecting and quantifying drugs and their metabolites in biological samples. It combines Liquid Chromatography (LC) with Tandem Mass Spectrometry (MS/MS) to achieve precise analysis. This method is widely used in clinical, forensic, and research settings for drug testing because of its superior accuracy and ability to analyse complex mixtures.

Why LC-MS/MS Is Preferred?

Unlike simpler drug screening methods like immunoassays, LC-MS/MS offers unmatched precision, which is critical for confirmatory drug testing or when detecting low-concentration or rare substances. It's particularly useful when high accuracy is required, such as in court cases or for regulatory compliance.

Key benefits:

  • Accuracy & reliability – The lab methods deliver higher specificity and sensitivity compared to on-site drug test kits and is used to confirm non negative on site drug test  results in workplace drug screening. 
  • Comprehensive screening – You can detect a wide range of drugs: cannabis (THC), cocaine, amphetamines, benzodiazepines, opiates, synthetic cannabinoids and more. 
  • Flexible sample types – We offer both urine and saliva-based lab testing options, so you can choose what best suits your circumstances. 

How it works

  1. Choose and purchase the appropriate test pack from our collection.
  2. Collect your sample (urine or saliva) following the kit instructions.
  3. Securely send the sample to the lab using the provided packaging.
  4. The laboratory completes the analysis and you receive a detailed report of the findings. 

Typical uses

  • Workplace drug screening – Employers wanting assurance of a drug-free environment often require lab-confirmed tests. 
  • Legal / court compliance – When results may be needed for legal or regulated processes, a laboratory drug test offers the necessary rigour.
  • Medical & rehabilitation monitoring – Doctors, clinics or rehabilitation programmes may use lab testing to track substance usage or compliance.

Choosing the right test for you

  • If you need the highest level of accuracy (for example, legal or occupational health purposes), opt for a lab confirmation test (LC-MS/MS or GC-MS).
  • If you prefer minimal intrusion and convenience, a saliva-based kit may be the best choice.
  • Consider how many substances you need to screen for: many packs include one drug by default, with the option to add further groups for an additional fee. Lab testing is more expensive than onsite drug screening so is not usually the first line of drug screening.
