Hair Follicle Drug Testing - Yelm, WA

What it is, How it works

Hair analysis is widely recognized as an effective tool for uncovering drug and alcohol consumption. Hair captures a long-term record of substances by embedding biomarkers within the hair strand as it grows. Collected near the scalp, hair can reveal a detection period of up to three months for both alcohol and drugs. The collection process is straightforward, difficult to tamper with, and easy to transport.

A sample size of 1.5 inches, consisting of approximately 200 hair strands (similar in thickness to a #2 pencil), provides around 100mg of hair, which is ideal for initial screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a specimen weight of 150mg is advised. It is suggested to weigh the hair sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be used. When we refer to head hair, we are specifically discussing scalp hair, whereas body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage of introducing a sample to the laboratory’s system. This step entails confirming that the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening is a preliminary assessment to swiftly identify drugs of abuse. While it is a cost-efficient method for eliminating drug use in most samples, a positive screening result requires confirmation to be legally valid. Any samples with presumptive positive results in Screening necessitate secondary confirmation.

For samples that yield presumptive positive results during Screening, additional hair is extracted from the initial sample for the Extraction phase. During this stage, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies.

Confirming any positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are washed before confirmation if necessary. The entire process, from Accessioning to Confirmation, is meticulously examined under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests detect for a shorter timeframe.
• Resistance to tampering: Manipulating a hair drug test is extremely challenging, thus enhancing result accuracy.
• Records historical usage: It outlines a pattern of drug use over time rather than just recent intake.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after usage.
• Expense: Hair drug tests are typically costlier compared to alternative testing methods.
• Result variability: Elements like hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests", the actual analysis involves only the hair strand rather than the subcutaneous follicle.
