Hair Follicle Drug Testing - Ringgold, MD

What it is, How it works

Hair analysis has emerged as a significant approach for identifying substance and alcohol consumption. Hair offers an extensive timeline of intoxicant and other substance usage by encapsulating biomarkers within the strands of growing hair. When obtained near the scalp, hair might reveal up to nearly a 3-month detection period for intoxicants and other substances. It's uncomplicated to acquire, relatively tricky to tamper with, and simple to transport.

A segment of 1.5 inches comprising roughly 200 hair strands (resembling the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which serves as the ideal specimen for analysis and validation. For EtG, supplementary tests, and/or examinations exceeding 10 panels, 150mg of the sample is advocated. We advise weighing the specimen utilizing a jeweler’s scale. Absent scalp hair, an equivalent portion of body hair can be obtained. Reference to head hair strictly pertains to scalp hair, while body hair encompasses all other types (like facial, axillary, and others).

Process Overview

The primary stages in a lab's handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a lab’s system. This phase involves authenticating that the specimen was properly sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and finalizing any auxiliary data input absent in an electronic custody system.

Screening involves an initial rapid assessment for substance misuse. Although Screening is an economical strategy to negate drug usage in the bulk of samples, a positive screening outcome necessitates confirmation for judicial acceptability. Any samples seemingly positive in Screening necessitate supplementary confirmation.

Should a specimen seem positive in Screening, additional strands are extracted from the primary sample for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other datasets (e.g., urine or oral fluid), making hair drug screening an intricate methodology.

Verification of any positive screening outcome is accomplished using GC/MS, GC/MS/MS or LC/MS/MS. All seemingly positive samples undergo washing before confirmation as required. The entire lab procedure from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace substance consumption up to 90 days, unlike urine tests which have a more limited detection timeframe.
• Enhance test credibility: Cheating a hair drug test is exceedingly challenging, rendering the results more reliable.
• Documents usage patterns: It can outline a history of substance consumption over time, not merely recent activity.

Limitations:

• Inability to detect recent consumption: It requires about 5-7 days for substances to become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs than other testing methods.
• Result variability: Aspects like hair color and individual hair growth variations can influence the concentration of drug metabolites within hair.

Note: Though often termed as "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.
