Hair Follicle Drug Testing - Vashon Island, WA

What it is, How it works

Hair testing has evolved as an influential method for identifying drug and alcohol consumption. The fibers of growing hair strands trap biomarkers, providing a prolonged trace of alcohol and drug usage. When collected near the scalp, hair samples can offer approximately a three-month detection period for substances such as alcohol. Hair is easy to collect, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch segment containing roughly 200 hair strands (comparable in size to a #2 pencil) closest to the scalp will yield 100mg of hair, an ideal quantity for both screening and confirming results. For EtG, additional testing, and/or screenings surpassing 10 panels, 150mg of the sample is advised. It's beneficial to weigh the hair sample using a jeweler’s scale. Should scalp hair be absent, an equivalent amount of body hair can be collected. "Head hair" specifically refers to scalp hair exclusively. "Body hair" covers all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results is comprised of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where the sample is processed into the laboratory's system. This phase ensures the sample was properly sealed and transported, associates a random LAN (Laboratory Accessioning Number) with it, and concludes any further data entry not provided by an electronic chain of custody system.

During the Screening phase, an initial rapid analysis is conducted for substances of abuse. Although Screening is economically efficient for eliminating drug usage in most samples, a positive screen requires subsequent confirmation to be upheld in legal contexts. Samples with presumptive positive results in Screening necessitate a follow-up confirmation.

When a sample tests presumptively positive in the Screening stage, additional hair is withdrawn from the original sample for the Extraction phase. At this point, drugs are extracted from hair at concentrations notably lower than those in alternate methodologies (for instance, urine or oral fluid), underscoring the complexity of hair drug screening versus other methodologies.

GC/MS, GC/MS/MS, or LC/MS/MS methods are employed for confirming any positive screening outcomes. Samples with presumptive positive findings are cleansed before confirmation as needed. The entire laboratory process, from Accessioning to Confirmation, is evaluated following both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair tests can detect drug use over a span of 90 days, unlike urine tests with shorter detection periods.
• Challenge in manipulation: Cheating a hair drug test is notably difficult, enhancing result reliability.
• Chronological data provision: It reveals a pattern of drug usage over time, rather than indicating merely recent consumption.

Limitations:

• Inability to detect recent use: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Generally, hair drug tests are pricier than other drug testing methods.
• Variability in outcomes: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though often termed as "hair follicle tests," this test examines the hair strand rather than the follicle beneath the scalp.
