Hair Follicle Drug Testing - Chitina, AK

What it is, How it works

Hair testing is regarded as a highly effective method for identifying drug and alcohol usage. Hair encapsulates a prolonged record of alcohol and other substances by embedding biomarkers within the strands of growing hair. When collected near the scalp, hair may provide a detection period that spans up to roughly three months for alcohol and other substances. Hair is easy to collect, relatively resistant to tampering, and straightforward to transport.

A 1.5-inch sample consisting of about 200 hair strands (approximately the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for testing and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of hair is suggested. It's advisable to measure the sample with a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair may be used. When mentioning head hair, this refers specifically to scalp hair. Body hair refers to all other types (facial, axillary, etc.).

Process Overview

The primary phases involved in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory’s system. This encompasses verifying the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.

Screening entails an initial rapid assessment for drug abuse. Although Screening is a cost-efficient measure to rule out drug use in most samples, a positive screen must be validated to be permissible in legal proceedings. Samples testing presumptive positive in Screening need additional confirmation.

If a sample tests as presumptive positive during Screening, further hair is extracted from the original sample and processed for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), which contributes to the complexity of hair drug testing.

Confirmation of any positive screening result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is evaluated following both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection duration: Hair drug testing can uncover drug use for as long as 90 days, unlike urine tests which have a more limited detection time.
• Challenge to manipulate: Manipulating a hair drug test is notably challenging, resulting in more reliable outcomes.
• Yields historical data: It provides a substance usage pattern over time, instead of only indicating recent use.

Constraints:

• Unable to identify recent use: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing methods.
• Result variability: Aspects such as hair color and individual differences in hair growth can impact drug metabolite concentrations in hair.

Note: While often called "hair follicle tests", the actual analysis focuses on the hair strand rather than the follicle beneath the scalp.
