Hair Follicle Drug Testing - Carsins, MD

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. It captures a comprehensive timeline of substance use by embedding biomarkers within the strands of hair as they grow. When harvested near the scalp, hair can reveal alcohol and drug usage for up to an approximately 90-day time frame. The collection of hair samples is straightforward, less prone to tampering, and simple to transport.

An ideal sample size includes a 1.5-inch segment containing roughly 200 hair strands (approximating the thickness of a #2 pencil) from near the scalp, providing 100mg of hair for assessment and validation. For tests exceeding 10 panels, the inclusion of EtG, and/or additional checks, a 150mg sample is advised. A jeweler’s scale is recommended for specimen measurement. In the absence of scalp hair, a comparable volume of body hair may be taken, noting that "head hair" specifically refers to scalp hair, while "body hair" indicates all other hair forms (such as facial, axillary, etc.).

Process Overview

The laboratory procedure for drug testing comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a specimen within a lab's framework. It includes ensuring the sample's proper sealing and shipping, assigning it a distinct LAN (Laboratory Accessioning Number), and finalizing any leftover data entry omitted by an electronic custody chain system.

Screening is an initial, rapid evaluation for drug presence. While Screening economically sifts out potential drug use in numerous samples, any positive results require confirmation to hold up in legal contexts. Presumptive positives in Screening necessitate subsequent confirmations.

When a sample returns a presumptive positive from Screening, additional hair is retrieved from the initial batch for the Extraction phase. Here, substances are extracted from hair at substantially lower concentrations than other methods (like urine or oral fluid), underscoring the complexity of hair drug analysis.

Positive screening results undergo validation through GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positive samples are pre-washed before confirmation, as required. From Accessioning through Confirmation, the entire laboratory procedure complies with the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair testing can uncover drug use for up to 90 days, unlike urine assessments with narrower detection spans.
• Hard to deceive: Creating false results for a hair drug test proves exceptionally challenging, enhancing result reliability.
• Offers historical insights: Displays a timeline of substance consumption, shedding light beyond just recent activity.

Limitations:

• Incapable of detecting recent usage: Drugs take approximately 5-7 days before they can be identified in hair strands.
• Costs: Compared to alternate drug-testing techniques, hair analyses typically incur higher expenses.
• Result variability: Elements such as hair color and personal differences in hair growth can sway the concentration levels of drug metabolites.

Note: Although colloquially termed "hair follicle tests", these tests actually assess the hair strands—not the follicles beneath the scalp.
