Hair Follicle Drug Testing - Lexington, VA

What it is, How it works

Hair testing has emerged as a significant instrument for identifying drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug use by capturing biomarkers within the strands of growing hair. When obtained near the scalp, hair can reveal up to a three-month detection span for alcohol and drugs. It's straightforward to collect hair, challenging to tamper with, and convenient to transport.

A sample of hair measuring 1.5 inches with about 200 strands (roughly the size of a #2 pencil) closest to the scalp yields 100mg of hair, regarded as the optimal sample for analysis and validation. For EtG, additional tests, and tests exceeding 10 panels, a specimen of 150mg is suggested. It's advisable to measure the specimen using a jeweler’s scale. If scalp hair is absent, a proportionate amount of body hair may be gathered. "Head hair" specifically refers to scalp hair exclusively. "Body hair" encompasses any other hair types (e.g., facial, axillary).

Process Overview

The primary stages in the laboratory analysis of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial entry of a sample into the lab’s system. This process ensures the sample is properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not captured by an electronic chain of custody system.

Screening entails a preliminary assessment for illicit drugs. Although Screening is a cost-effective method to negate drug use in most samples, any positive screen must be confirmed to be court-admissible. Samples that show a presumptive positive in Screening demand a follow-up confirmation.

In instances where a sample shows a presumptive positive in Screening, additional hair is extracted from the original specimen and prepared for Extraction. In this stage, drugs are extracted from hair at much lower concentrations than in other methods (such as urine or oral fluid), highlighting why hair drug screening is notably complex.

Any affirmative screening result is verified using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and accredited to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for as long as 90 days, unlike urine tests, which have a more limited detection period.
• Challenging to deceive: Cheating a hair drug test is notably difficult, ensuring more reliable results.
• Offers historic patterns: It can display a pattern of drug use over time, rather than only recent use.

Limitations:

• Incapable of identifying recent use: It requires about 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variations: Factors such as hair color and individual differences in hair growth can influence drug metabolite concentration in the hair.

Note: While commonly referred to as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
