Hair Follicle Drug Testing - Vesuvius, VA

What it is, How it works

The use of hair for detecting drug and alcohol consumption has gained recognition due to its effectiveness. Hair retains a long-term record of substances by embedding biomarkers within its fibers as it grows. When collected close to the scalp, hair can offer an approximate 3-month detection timeframe for alcohol and other drug use. Collecting hair samples is straightforward, relatively tamper-resistant, and easy to transport.

A sample size of 1.5 inches, consisting of around 200 hair strands (equivalent to a #2 pencil's thickness) near the scalp, provides 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a sample of 150mg is suggested. It's advisable to use a jeweler’s scale for weighing the sample. If scalp hair isn't available, a corresponding amount of body hair can be gathered. The term head hair specifically pertains to scalp hair, while body hair encompasses other types (such as facial, axillary, etc.).

Process Overview

The laboratory process for processing a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial entry of a sample into the lab's system. This step entails checking that the sample is properly sealed and shipped, issuing a random LAN (Laboratory Accessioning Number), and entering any additional information not captured by an electronic chain of custody system.

Screening involves an initial rapid assessment for substances of abuse. While Screening efficiently rules out drug use for most samples, a positive screen must be confirmed to be legally valid. Any samples indicated as presumptively positive in Screening necessitate a confirmatory procedure.

If a sample appears positive during the Screening phase, further hair is taken from the original batch and readied for Extraction. During Extraction, drugs are drawn out from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), highlighting why hair drug testing is the most complex methodology.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS equipment. All samples yielding presumptive positives are cleansed prior to confirmation as necessary. The entire lab process from Accessioning to Confirmation is subjected to review under both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests with a shorter detection period.
• Resistance to tampering: Cheating a hair drug test is quite challenging, enhancing result accuracy.
• Historical usage overview: It offers an overview of drug usage patterns over time rather than just recent activity.

Limitations:

• Inability to detect recent usage: It takes approximately 5-7 days for drugs to be visible in hair samples.
• Expense: Hair drug tests typically incur higher costs than other testing methods.
• Result variations: Aspects such as hair color and individual growth patterns can influence drug metabolite levels in hair.

Note: Often labeled as "hair follicle tests", the analysis actually inspects the hair strand rather than the follicle beneath the scalp.
