Hair Follicle Drug Testing - Barclay, MD

What it is, How it works

Hair testing has been acknowledged as a robust means of identifying substance use involving drugs and alcohol. Hair serves as a chronological record of alcohol and drug consumption by embedding biomarkers within the hair’s growing strands. By securing hair near the scalp, it offers a retrospective detection span of nearly three months for substances. The collection of hair is straightforward, relatively resistant to tampering, and convenient for shipping.

A 1.5-inch portion of approximately 200 hair strands (comparable to the thickness of a #2 pencil) obtained closest to the scalp will yield 100mg of hair, the optimal amount for both screening and confirmation. For EtG, supplemental tests, and/or assessments exceeding 10 panels, 150mg of the sample is suggested. It is advisable to use a jeweler’s scale to weigh the sample. If scalp hair cannot be accessed, a proportional quantity of body hair can be gathered. When mentioning head hair, it pertains solely to scalp hair. Alternatively, body hair refers to all non-scalp hair types (facial, axillary, etc.).

Process Overview

The basic phases in the laboratory assessment of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial setup of a specimen into the laboratory’s database. This procedure entails the validation of the sample’s seal status and shipment, assignment of a random LAN (Laboratory Accessioning Number), and execution of any supplementary data entry absent from an electronic chain of custody record.

Screening signifies an initial expeditious inspection for illicit substances. Even though Screening represents a cost-efficient means to dismiss drug usage across numerous samples, an affirmative screening outcome requires corroboration for judicial acceptance. All samples suspected of being positive during Screening necessitate a secondary confirmation.

In the event a sample is suspectively positive in the Screening phase, additional hair is extracted from the primary sample and readied for Extraction. Within this phase, drugs are eluted from hair in far lower concentrations compared to other techniques (e.g., urine or oral fluid), establishing hair drug screening as a challenging procedure to administer.

Confirmation of all positive screening outcomes is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing of any suspectively positive samples is performed before confirmation. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair category and the accreditation to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Extended detection range: Hair drug evaluations can identify drug consumption over a period of up to 90 days, contrasting with urine tests that have a briefer detection span.
• Challenging to manipulate: Cheating a hair drug test is extremely difficult, ensuring the accuracy of results.
• Historical usage portrayal: It reveals a timeline of drug consumption, not limited to recent use.

Limitations:

• Limited recent usage detection: It necessitates about 5-7 days for drugs to be traceable in hair.
• Economic factor: Hair drug assessment tends to be costlier compared to alternative drug testing approaches.
• Result variability: Elements such as hair hue and individual hair growth disparities may influence the drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests," the analysis is conducted on the hair strand and not the hair follicle beneath the scalp.
