Hair Follicle Drug Testing - Avenue, MD

What it is, How it works

The usage of hair testing has gained a reputation as an effective means for identifying drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug intake by embedding biomarkers within its fibers. When collected near the scalp, hair offers a detection timeframe of up to around 3 months for alcohol and drugs. It is easy to gather, less susceptible to tampering, and simple to transport.

A sample of 1.5 inches with approximately 200 hair strands (about the size of a #2 pencil) near the scalp provides 100mg of hair, the optimal sample amount for both screening and confirmation. For EtG, additional tests, and/or more than 10 panel tests, 150mg of the sample is advisable. We suggest using a jeweler’s scale to measure the sample weight. In cases where scalp hair is not available, a similar quantity of body hair can be collected. When we mention head hair, it specifically refers to scalp hair. Body hair denotes all other types of hair (facial, axillary, etc.).

Process Overview

The four vital steps in the laboratory processing of drug test results consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial handling of a sample into the lab’s system, ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data not available via an electronic chain of custody system.

Screening is a preliminary rapid assessment for drugs of abuse. Although Screening is an economical approach to dismiss drug usage for most samples, a positive result needs confirmation for legal use. Samples with a presumptive positive in Screening require secondary confirmation.

If a presumptive positive is noted in the Screening phase, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair with lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology to execute.

Confirmation of any positive screen result is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a shorter detection period.
• Difficulty to cheat: It is exceedingly challenging to trick a hair drug test, ensuring more accurate results.
• Provides historical data: It offers a pattern of drug usage over time, not merely recent consumption.

Limitations:

• Cannot detect recent use: It requires about 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests are typically costlier than other drug testing techniques.
• Variations in results: Elements like hair color and individual hair growth variations can influence the concentration of drug metabolites in hair.

Note: While frequently termed as "hair follicle tests," the test actually examines the hair strand rather than the follicle beneath the scalp.
