Hair Follicle Drug Testing - Kingsdale, MN

What it is, How it works

Hair testing has emerged as an influential method for uncovering drug and alcohol consumption. Hair captures a historical record of alcohol and drugs by securing biomarkers within the hair strand's fibers during its development. When sourced close to the scalp, hair can present nearly a 3-month period for identifying alcohol and drug presence. Collection of hair is straightforward, relatively challenging to tamper with, and conveniently shipped.

A 1.5-inch portion of roughly 200 hair strands (equivalent to the circumference of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for both screening and verification. For EtG, extensions, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It is advisable to measure the sample weight using a jeweler’s scale. If scalp hair cannot be obtained, a comparable quantity of body hair may be gathered. References to head hair pertain specifically to scalp hair. Conversely, body hair includes all other types (facial, axillary, etc.).

Process Overview

The four primary stages in the laboratory analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a laboratory's database. This step involves ensuring the sample is correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input not accounted for by an electronic chain of custody system.

Screening consists of a rapid preliminary check for substance abuse. While Screening is an economical method to dismiss drug usage in most samples, a positive result necessitates confirmation for legal acceptability. Samples exhibiting presumptive positivity in Screening need secondary confirmation.

Should a sample be presumptively positive at the Screening phase, additional hair is extracted from the original specimen and arranged for Extraction. During this phase, drugs are extracted from hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), which accounts for the complexity of hair drug screening.

Confirmation of any positive Screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positivity undergo cleansing before confirmation if needed. The entirety of the laboratory process, spanning from Accessioning to Confirmation, is conducted under the scrutiny of both the CAP (College of American Pathologists) Hair designation and the accreditation conforming to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Extended detection duration: Hair drug screenings can reveal drug use for as long as 90 days, compared to urine tests which offer a shorter detection period.
• Challenging to manipulate: Outmaneuvering a hair drug test proves considerably difficult, enhancing result accuracy.
• Delivers historical insights: It can illustrate a drug use pattern over a span of time, extending beyond immediate consumption.

Limitations:

• Unable to identify immediate usage: Approximately 5-7 days are required for drugs to become evident in hair.
• Expense: Generally, hair drug screenings incur greater costs than other testing modes.
• Result variations: Aspects such as hair color and personal idiosyncrasies in hair growth can influence the concentration of drug metabolites within hair.

Note: Commonly termed as "hair follicle tests", this test scrutinizes the hair strand rather than the follicle beneath the scalp.
