Hair Follicle Drug Testing - Woodstock, MD

What it is, How it works

Hair testing has emerged as a remarkable resource for identifying drug and alcohol consumption. Hair offers a prolonged history of alcohol and other drugs by encapsulating biomarkers within the strands as they grow. When taken near the scalp, hair can reveal up to an approximate 3-month timeframe for detecting alcohol and other substances. The collection process is straightforward, somewhat hard to alter, and simple to send.

A sample size of 1.5 inches, containing around 200 hair strands (similar to the diameter of a #2 pencil), closest to the scalp will provide 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional add-ons, and/or testing on more than 10 panels, a 150mg sample is advised. It's suggested that the specimen be weighed using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair may be used. When discussing head hair, we refer exclusively to scalp hair. Body hair encompasses all other types, such as facial and axillary.

Process Overview

The key stages in processing a drug test in the laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial phase where a sample is introduced into a laboratory system. This step involves ensuring the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not covered by an electronic chain of custody system.

Screening uses an initial rapid test for banned substances. Although Screening is a cost-effective approach to eliminate drug usage in most samples, a positive result needs verification to be valid in court. Any samples that return a presumptive positive during Screening will require a follow-up confirmation.

If a sample tests presumptively positive in the Screening phase, more strands are separated from the initial specimen to prepare for Extraction. During this stage, substances are extracted from hair at a substantially lower concentration than with other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging methodology to execute.

Confirmation of any positive outcome in the screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation if necessary. From Accessioning to Confirmation, the entire laboratory process is examined under CAP (College of American Pathologists) Hair designation and compliant with ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize substance use for up to 90 days, unlike urine tests which have a more restricted detection period.
• Difficult to evade: It is notably tough to deceive a hair drug test, thereby enhancing the accuracy of results.
• Gives historical insight: It offers a usage pattern over time instead of just recent use.

Limitations:

• Inability to detect recent consumption: It takes about 5-7 days for drugs to become detectable in hair strands.
• Expense: Hair drug tests usually cost more compared to other drug testing techniques.
• Variability in outcomes: Elements such as hair color and differences in individual hair growth can impact the levels of drug metabolites in the hair.

Note: Although commonly mentioned as "hair follicle tests", the analysis focuses on the hair strand and not the follicle beneath the scalp
