Hair Follicle Drug Testing - Harwood, MD

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol usage. Hair strands hold biomarkers, giving insight into long-term drug and alcohol consumption by embedding them within the growing hair's fibers. When closely collected to the scalp, hair facilitates an alcohol and drug detection timeframe of up to roughly three months. It is easy to gather, difficult to tamper with, and straightforward to send.

Collecting a 1.5-inch sample consists of approximately 200 strands of hair (similar to a #2 pencil's thickness) from near the scalp, yielding 100mg, the optimal amount for screening and validation. For EtG add-ons or tests exceeding 10 panels, a sample weighing 150mg is advised. Using a jeweler’s scale to measure the specimen is recommended. If scalp hair is unavailable, an equivalent amount of body hair can be collected. "Head hair" specifically refers to scalp hair alone, while "body hair" encompasses types like facial or axillary hair.

Process Overview

Laboratory processing of a drug test result comprises four main activities: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to initially integrating a specimen into the laboratory’s system, ensuring it was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry tasks not provided by an electronic chain of custody system.

Screening represents an initial assessment aimed at detecting drug misuse. While screening is an affordable approach to exclude drug use in most samples, any positive screening findings require confirmation to be court-admissible. Samples with a presumptive positive screening result necessitate secondary verification.

For samples showing presumptive positives during screening, additional hair from the original sample is extracted and prepared specifically for the Extraction phase. Hair allows drug removal at significantly lower concentrations than other methods (e.g. urine or oral fluid), hence it poses the most challenging methodology to execute.

All positive screenings are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. As needed, presumed positive samples undergo water rinsing before confirmation. The entire process from Accessioning to Confirmation is assessed according to both the CAP (College of American Pathologists) Hair designation and accredited ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests trace drug consumption for up to 90 days, unlike urine tests with shorter detection spans.
• High resistance to deception: It is notably challenging to deceive a hair drug test, enhancing the reliability of the results.
• Historical usage insights: It unveils a drug use pattern across a timeframe instead of merely highlighting recent usage.

Limitations:

• Inability to identify recent usage: Drugs generally require around 5-7 days to become detectable in hair.
• Higher expense: Hair drug tests typically entail more costs than alternative drug testing approaches.
• Result variability: Elements like hair color and personal hair growth variations can influence drug metabolite concentration in the hair.

Note: Despite often being referred to as "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.
