Hair Follicle Drug Testing - Dodson Branch, TN

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. Hair captures a comprehensive history of alcohol and other substances by embedding biomarkers within the strands of hair as they grow. When collected from the scalp, hair can offer a detection period of up to roughly three months for alcohol and various drugs. The collection process is straightforward, moderately resistant to tampering, and simple to transport.

A 1.5-inch portion consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) taken closest to the scalp yields 100mg, which is the preferred amount for analysis and validation. For EtG additional tests and those exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for measuring the specimen is suggested. If scalp hair cannot be sourced, a similar quantity of body hair may be used. References to head hair denote exclusively scalp hair. Body hair covers all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug test results encompasses four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the preliminary incorporation of a specimen into the laboratory system. It involves confirming that the sample was appropriately sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data input not submitted via an electronic chain of custody system.

Screening is a preliminary rapid assessment for substances of abuse. While it serves as an economical approach to exclude drug use in the bulk of samples, positive results from Screening necessitate confirmation to be legally valid. Samples showing presumptive positivity in screening need additional confirmation.

In cases where a sample indicates presumptive positivity at the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. During this phase, drugs are extracted from hair in lower concentrations than found in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening procedures.

Positive screening results go through Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing prior to confirmation if needed. The complete lab process from Accessioning through to Confirmation is evaluated under the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use spanning up to 90 days, whereas urine tests offer a shorter detection period.
• Challenging to evade: Evading a hair drug test is notably difficult, leading to more reliable outcomes.
• Delivers historical insights: It can illustrate a timeline of drug usage over an extended period, as opposed to merely recent usage.

Limitations:

• Inability to identify recent usage: Drugs become detectable in hair roughly 5-7 days after consumption.
• Expense: Hair drug tests typically incur higher costs compared to other testing techniques.
• Result variability: Elements like hair color and individual differences in hair growth can influence the levels of drug metabolites in the hair.

Note: Often referred to as "hair follicle tests," this type of test actually examines the hair strand rather than the follicle beneath the scalp.
