Hair Follicle Drug Testing - Castle Rock, WA

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair offers an extended timeline of drug and alcohol intake by capturing biomarkers within the fibers as the hair grows. When taken close to the scalp, hair provides a detection window of approximately three months for drugs and alcohol. Hair collection is straightforward, not easily tampered with, and convenient to transport.

A 1.5-inch hair sample, consisting of about 200 strands (comparable in size to a #2 pencil) from the scalp, will yield 100mg of hair, which is the optimal sample size for screening and verification. For EtG, additional tests, and tests exceeding 10 panels, a 150mg specimen is preferred. It's advisable to measure the specimen using a jeweler’s scale. If the scalp hair is not available, an equal quantity of body hair may be collected. When mentioning head hair, it specifically means scalp hair, while body hair encompasses all other hair such as facial and axillary hair.

Process Overview

The laboratory processing of a drug test result comprises four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage, where a sample is processed into the laboratory system. This step ensures the sample is properly sealed and shipped, assigns it a random LAN (Laboratory Accessioning Number), and completes any remaining data entry absent from the electronic chain of custody system.

Screening involves a preliminary evaluation for drugs of abuse. While Screening is economically efficient for ruling out drug use in most samples, any positive results need further confirmation to be valid in legal contexts. Samples that yield a presumptive positive in Screening require additional verification.

Samples that register as presumptively positive in the Screening phase have more hair isolated from the initial sample and are readied for Extraction. During this phase, drugs are isolated from the hair at lower concentrations compared to other techniques (for example, urine or oral fluid), which makes hair drug analysis one of the most challenging techniques to execute.

Positive results from Screening are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo a washing process before confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for as long as 90 days, whereas urine tests have a much shorter window.
• Hard to falsify: Cheating on a hair drug test is very challenging, thus ensuring more reliable results.
• Historical data provision: It supplies a chronological pattern of drug use over time, unlike tests focusing only on recent use.

Limitations:

• Inability to detect recent use: Drugs typically take 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically costlier compared to other drug testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence the levels of drug metabolites in hair.

Note: Referred to as "hair follicle tests," the evaluation actually examines the hair strand, not the follicle beneath the scalp.
