Hair Follicle Drug Testing - Keedysville, MD

What it is, How it works

Hair testing is increasingly regarded as a highly effective method for detecting drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug usage by embedding biomarkers within the strands as they grow. Hair samples collected near the scalp can offer up to roughly a 3-month period of drug and alcohol detection. Hair is straightforward to collect, relatively tamper-resistant, and easy to transport.

A sample size of 1.5 inches, consisting of roughly 200 hair strands (about the diameter of a #2 pencil) nearest the scalp, yields 100mg of hair, the preferred amount for initial testing and confirmation. For EtG tests, add-ons, or screenings exceeding 10 panels, a specimen amount of 150mg is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not available, a similar quantity of body hair can be utilized. When we mention head hair, it specifically implies scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first phase, which involves processing the sample into a lab’s system. This step checks that the sample was sealed and sent appropriately, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not handled by an electronic chain of custody system.

Screening is the next phase, providing an initial rapid assessment for drugs of misuse. Although Screening is an economical method to eliminate drug usage in most samples, a positive result from Screening requires confirmation for court admissibility. Samples showing presumptive positive results in Screening need additional confirmation.

If a sample results in a presumptive positive during Screening, more hair is extracted from the initial sample for the Extraction process. Here, drugs are extracted from hair at lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug screening presents the highest level of difficulty among testing methodologies.

The Confirmation process for any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all presumptive positive samples undergo necessary washing. From Accessioning to Confirmation, the entire lab process is conducted under the CAP (College of American Pathologists) Hair designation and follows accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Challenging to adulterate: Hair drug tests are very challenging to cheat, ensuring more reliable results.
• Historical usage data: These tests can show patterns of drug use over time, not just recent usage.

Limitations:

• Cannot ascertain recent usage: It requires about 5-7 days for drugs to become apparent in hair samples.
• Expense: Hair drug testing is generally costlier than other testing methods.
• Result variations: Hair color and individual differences in hair growth can influence the concentration of drug metabolites found in hair.

Note: Although often called "hair follicle tests", the analysis focuses on the hair strand itself and not the follicle beneath the scalp.
