Hair Follicle Drug Testing - Donovan Estates, AZ

What it is, How it works

Hair testing is now recognized as a significant method for detecting drug and alcohol use. It offers a long-term record of alcohol and other drug usage by embedding biomarkers within the strands of growing hair. Hair collected from near the scalp can reveal a detection period of up to about three months for alcohol and other drugs. The collection process for hair is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch section, involving around 200 strands of hair, roughly the thickness of a #2 pencil, collected closest to the scalp, yields approximately 100mg, which is the ideal amount for screening and confirmation. For tests involving EtG, additional types, and/or those exceeding 10 panels, 150mg is suggested. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent quantity of body hair can be used. When referencing head hair, it pertains solely to scalp hair. Body hair encompasses all other types (e.g., facial or axillary).

Process Overview

There are four key stages in the laboratory process to determine a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage that introduces a sample into the laboratory system. This step ensures that the sample was sealed and transmitted correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any data entry not provided by an electronic chain of custody system.

Screening offers a primary, rapid assessment for the presence of drugs. While Screening is an efficient method to exclude drug use for most samples, a positive screen necessitates confirmation to be valid in legal settings. All specimens that test presumptively positive in Screening must undergo subsequent confirmation.

In the Screening phase, if a sample tests presumptively positive, additional hair is extracted from the initial sample and prepared for Extraction. Drugs are extracted from hair at notably lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies.

Confirmation of any positive screen result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive are cleansed before confirmation when necessary. The complete lab process, from Accessioning to Confirmation, is overseen under the designations of both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days prior, unlike urine tests, which have a shorter detection duration.
• Hard to manipulate: Hair drug tests are exceptionally challenging to falsify, ensuring more precise outcomes.
• Offers historical insight: It can provide a historical pattern of drug use, not solely recent incidences.

Limitations:

• Inability to detect recent usage: It requires about 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests are often more costly than alternative testing methods.
• Result variances: Factors like hair color and individual hair growth differences can impact metabolite concentration within the hair.

Note: Frequently termed "hair follicle tests", the test actually examines the hair strand itself, not the follicle beneath the scalp.
