Hair Follicle Drug Testing - St. George Island, MD

What it is, How it works

The utilization of hair testing has emerged as a robust technique in identifying alcohol and drug consumption. By encapsulating biomarkers within the strands of hair, it offers a comprehensive account of substance use. Hair collected near the scalp can provide a detection timeframe of up to around three months for both alcohol and drugs. It is straightforward to gather, challenging to tamper with, and convenient for shipment.

An optimal sample consists of a 1.5-inch segment, totaling around 200 hairs (approximately the width of a #2 pencil), positioned nearest to the scalp, yielding 100mg of hair. This quantity is ideal for both testing and confirmation. For EtG, additional tests, or those exceeding 10 panels, a minimum of 150mg is preferable. We suggest measuring the sample using a jeweler’s scale. If scalp hair isn't accessible, an equivalent portion of body hair can be utilized. When discussing head hair, it specifically means scalp hair. Body hair encompasses all other types (like facial or axillary).

Process Overview

Key stages in processing a drug test result within the laboratory encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary integration of a sample into a laboratory’s system. This stage involves ensuring the sample's seal and proper shipment, generating a unique LAN (Laboratory Accessioning Number), and executing any supplementary data entry absent in an electronic chain of custody system.

Screening entails an initial swift examination for drug abuse indicators. Although Screening is a cost-efficient way to negate drug consumption in most cases, a positive screen must be corroborated for legal validity. Any samples that test presumptively positive during Screening need a follow-up confirmation.

When a specimen tests presumptively positive at the Screening phase, further hair is extracted from the original sample and readied for Extraction. At this juncture, drugs are extracted at notably lower concentrations compared to other methods (such as urine or oral fluids), thereby classifying hair drug screening as one of the most intricate methodologies to execute.

Confirmation of any positive screening outcome employs GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed if necessary. From Accessioning to Confirmation, the entire laboratory procedure is evaluated under both the CAP (College of American Pathologists) Hair designation as well as accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can reveal drug use for a duration of up to 90 days, unlike urine tests which have a more limited detection span.
• Hard to evade: Cheating a hair drug test is highly challenging, thus rendering the results more precise.
• Longitudinal data provision: It offers a record of drug use across a timeframe, not merely recent use.

Limitations:

• Inability to detect recent consumption: A period of approximately 5-7 days is required for drugs to be perceptible in hair.
• Expense: Hair drug testing tends to be costlier compared to alternative drug testing approaches.
• Result variability: Elements like hair color or individual differences in hair growth can influence drug metabolite levels in hair.

Note: Despite often being called "hair follicle tests", the analysis focuses on the hair strand itself and not the follicle beneath the scalp.
