Hair Follicle Drug Testing - Abingdon, MD

What it is, How it works

Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. Hair strands provide an extended record of substance use by embedding biomarkers in the strands as they grow. When hair is cut close to the scalp, it can offer a detection period of up to three months for drugs and alcohol. Collection is straightforward, alteration is challenging, and shipping is hassle-free.

A sample measuring 1.5 inches and containing approximately 200 hair strands (similar in size to a #2 pencil) near the scalp is ideal, amounting to 100mg for testing purposes. For EtG-related tests and those exceeding ten panels, a 150mg sample is suggested. Using a jeweler's scale to weigh the sample is advised. If scalp hair is not available, an equivalent volume of body hair may be used. The term "head hair" specifically refers to scalp hair, whereas "body hair" includes all other hair types (such as facial and axillary).

Process Overview

The laboratory processing of drug tests involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample within the laboratory system. This stage ensures the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and includes any additional data entry that may not be covered by an electronic chain of custody system.

Screening is a preliminary assessment for substances of abuse. Although it is a cost-efficient method for eliminating the likelihood of drug usage in most samples, a positive screen necessitates confirmation for legal acceptance. Positive results from the Screening stage require a secondary verification.

When Screening yields a presumptive positive, further hair is extracted from the sample for the Extraction phase. In this stage, drugs are isolated from hair at lower concentrations than in other techniques (like urine or oral fluid), contributing to the complexity of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS are employed for validating any positive screening outcome. All samples tested positive during the prescreening undergo a washing step before confirmation, if needed. The process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection span: Hair tests can identify drug use for as long as 90 days, exceeding the duration of urine tests.
• Resistance to tampering: Hair tests are hard to manipulate, ensuring more reliable findings.
• Historical insight: It delivers a timeline of drug use over months rather than just recent consumption.

Limitations:

• Recent consumption undetected: Drugs become identifiable in hair about 5-7 days after use.
• Expense: Hair testing typically costs more than alternative drug testing techniques.
• Result variability: Influences like hair color and individual hair growth rates may impact drug metabolite concentration in hair.

Note: Often called "hair follicle tests", the assessment actually examines the hair strand, not the follicle beneath the scalp.
