Hair Follicle Drug Testing - Bier, MD

What it is, How it works

Utilizing hair testing has emerged as a potent method for identifying alcohol and drug consumption. Hair services as an extended timeline of substance use by encasing biomarkers within the hair's expanding fibers. When sourced near the scalp, hair can disclose drug and alcohol usage within approximately a 3-month period. Its collection process is straightforward, challenging to tamper with, and conveniently shippable.

A 1.5-inch segment encompassing roughly 200 strands of hair (approximately a #2 pencil's girth) nearest to the scalp yields 100mg, optimal for screening and confirmation purposes. For EtG, add-on assessments, or tests exceeding 10 panels, 150mg is advisable. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is absent, comparable quantities of body hair can be collected. References to head hair pertain solely to scalp hair. Body hair encompasses all other varieties (e.g., facial, axillary).

Process Synopsis

The key phases in laboratory analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary handling of a specimen into a lab's system. This process encompasses the verification of the sample's proper sealing and shipment, allocation of a random LAN (Laboratory Accessioning Number), and completion of any further data input absent an electronic chain of custody protocol.

Screening serves as an initial evaluation for abusive drugs. Despite being a cost-efficient means to negate drug consumption in most specimens, a positive screen necessitates confirmation for legal acceptance. Any samples yielding a presumptive positive from Screening mandate subsequent validation.

Should a sample indicate a presumptive positive during Screening, additional hair is drawn from the original sample for Extraction preparation. This phase involves drug extraction from hair at significantly reduced concentrations compared to other techniques (e.g., urine or oral fluid), highlighting hair drug screening as the most intricate methodology to execute.

Substantiation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive specimens undergo laundering as requisite. The comprehensive laboratory process, from Accessioning through Confirmation, adheres to the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 standards accreditation.

Benefits of hair drug testing:

• Extended detection duration: Hair drug screens can recognize drug ingestion for a span of up to 90 days, contrasting with urine tests with shorter detection periods.
• Resistance to falsification: Hair drug tests are very challenging to deceive, thereby enhancing result accuracy.
• Historical insight: It reveals an enduring drug consumption pattern over time, beyond mere recent usage.

Challenges:

• Incapability of detecting recent ingestion: Detectability in hair requires an estimated 5-7 day timeframe post-consumption.
• Expense: Hair drug analyses tend to incur higher costs than alternative testing methods.
• Result variability: Influences such as hair pigmentation and personal hair growth idiosyncrasies might impact drug metabolite concentrations within hair.

Note: Although frequently termed as "hair follicle tests," the actual examination involves the hair strand rather than the under-scalp hair follicle.
