FAQ About Drug Testing Services

What technique is used for a drug screening test?

In the world of drug testing, various techniques are utilized to detect the presence of drugs in an individual’s system. These techniques play a vital role in ensuring public safety. Learn more below.

Drug screening is a method employed to analyze biological samples, such as urine, blood, or hair, for the presence of drugs or related metabolites. It helps assess whether an individual has consumed illicit substances or prescription medications beyond designated levels.

The most commonly used technique in drug screening is immunoassay. It relies on antibodies to detect specific drugs or drug classes. Immunoassays are efficient and cost-effective, making them popular for initial drug screening. They provide rapid results and can identify a range of substances, from amphetamines to opioids.

To confirm the presence of drugs identified in the initial immunoassay, Gas Chromatography-Mass Spectrometry (GC-MS) is often employed. This technique separates and analyzes drug compounds based on their molecular characteristics. GC-MS offers high sensitivity and specificity, making it a reliable method for confirmation testing.

Liquid Chromatography-Mass Spectrometry (LC-MS) is an alternative to GC-MS for confirmatory testing. It separates and analyzes drug compounds based on their interactions with liquid phases. LC-MS is especially valuable for drugs that do not readily meet the requirements for GC-MS analysis.

Hair testing is a technique used for detecting long-term drug use. It involves analyzing sections of a person’s hair strands to identify drug metabolites. As hair grows relatively slowly, this method can provide a historical record of drug use over several months.

Urine testing is a prevalent method of drug screening. It involves analyzing a urine sample for drugs or their metabolites. This technique is affordable, non-invasive, and provides a reliable indication of recent drug use.

Oral fluid testing, known as saliva testing, is gaining popularity as a drug screening technique. It detects drugs present in the oral fluid through a simple mouth swab. This method is best for detecting recent drug use, as drug residues remain in the oral cavity only for a limited time.

Point-of-care testing has revolutionized drug screening by allowing tests to be conducted on-site, providing immediate results. These tests utilize techniques such as immunoassays or chromatography and are often used in workplace settings or roadside drug testing.

Below is a step-by-step procedure on how to perform a drug test.

  1. Determine the Purpose: Understand the reason for administering a drug screening test, whether it’s for employment, legal compliance, or personal reasons.
  2. Choose the Sample Type: Select the appropriate sample type based on the purpose of the test. Options include urine, blood, hair, or oral fluid.
  3. Collect the Sample: Follow proper collection procedures to ensure accurate and contamination-free samples. Use appropriate tools, such as specimen cups or swabs.
  4. Identify the Testing Method: Decide on the initial testing method, such as immunoassay. This will detect the presence of drugs or drug classes in the sample.
  5. Perform the Initial Test: Conduct the initial test using the chosen method. Follow the instructions provided with the testing kit.
  6. Interpret Results: Understand the interpretation criteria for the initial test to determine whether it is positive or negative.
  7. Confirm Positive Results: If the initial test is positive, proceed with the confirmation test. Use techniques like GC-MS or LC-MS to confirm and quantify the identified substance.
  8. Analyze Confirmation Results: Evaluate the confirmation test results based on pre-established thresholds and guidelines to confirm the presence of the specific drug.
  9. Consider Adulteration: Check for tampering or sample adulteration, which may impact test results. Follow protocols to identify potential manipulation.
  10. Report Generation: Prepare a detailed report including sample information, testing methods used, and results for documentation purposes.
  11. Communicate Results: Provide the results to the relevant parties and ensure confidentiality and privacy requirements are met.
  12. Follow Legal and Ethical Guidelines: Adhere to legal and ethical guidelines throughout the testing process to protect the rights and privacy of individuals involved.
  13. Evaluate Quality Assurance: Implement quality control measures to ensure accurate and reliable drug screening results. Regularly monitor and verify the performance of testing equipment and personnel.
  14. Stay Updated: Stay abreast of advancements in drug screening techniques and legal regulations to ensure reliable and up-to-date testing procedures.
  15. Seek Professional Assistance: When in doubt, or for complex cases, consult professionals or accredited laboratories specializing in drug testing.
  16. Maintain Documentation: Maintain accurate records of all drug screening tests conducted, including sample collection, analysis, and reports, for future reference and auditing purposes. In conclusion, understanding the techniques employed in drug screening tests is crucial for ensuring accuracy and reliability in identifying drug use. Immunoassay, GC-MS, LC-MS, hair testing, urine testing, oral fluid testing, and point-of-care testing are commonly utilized techniques. By following the above step-by-step procedure, you can confidently perform a drug screening test, contributing to a safer and drug free environment.


Remember, in drug screening, accuracy and reliability are paramount. Seek professional advice when necessary and ensure compliance with legal and ethical standards to achieve the best results.
