Hair Follicle Drug Testing - Las Nutrias, NM

What it is, How it works

Hair testing is recognized as a robust method for detecting drug and alcohol use. Hair maintains a prolonged record of alcohol and other substances by trapping markers within the strands' fibers. When gathered near the scalp, hair offers a detection period extending up to roughly 3 months for alcohol and various drugs. Hair collection is straightforward, relatively challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches comprised of roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimum quantity for screening and verification. For EtG add-ons and/or examinations exceeding 10 panels, a specimen weighing 150mg is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. If scalp hair is unavailable, an equivalent amount of body hair may be utilized. Head hair specifically refers to scalp hair, whereas body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial entry of a sample into a laboratory system. This phase includes ensuring the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.

Screening entails a preliminary rapid assessment for drugs. Although Screening is efficient for ruling out drug use in most samples economically, a positive screen must be verified for legal proceedings. Any samples initially positive in Screening necessitate a subsequent confirmation.

When a sample tests positive in the Screening phase, additional hair is extracted from the primary specimen and readied for Extraction. This phase sees drugs being drawn out from hair at substantially reduced concentrations compared to other methods (e.g., urine or oral fluid), highlighting the intricacy of hair drug screening as a methodology.

Confirmation of a positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples undergo necessary washing before confirmation. The complete laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can detect drug use for up to 90 days, unlike urine tests with shorter detection windows.
• Difficult to manipulate: Cheating a hair drug test is quite challenging, resulting in more reliable outcomes.
• Provides usage patterns: It can detail a pattern of drug use over an extended period, beyond recent consumption.

Limitations:

• Unable to detect recent use: It takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other methods.
• Outcome variability: Aspects such as hair color and individual growth rates can influence metabolite concentration in hair.

Note: Although often labeled as "hair follicle tests", the procedure examines the hair strand rather than the follicle within the scalp.
