Hair Follicle Drug Testing - Wharncliffe, WV

What it is, How it works

Hair testing has emerged as a potent mechanism for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering an extended timeline of substance use. When collected near the scalp, hair can exhibit up to approximately a three-month period of detectability for drugs and alcohol usage. Hair samples are easy to collect, challenging to tamper with, and convenient to transport.

A hair sample consisting of 1.5 inches with around 200 strands (similar in size to a #2 pencil) collected nearest to the scalp will yield 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, supplementary tests, and/or tests exceeding 10 panels, a sample weighing 150mg is suggested. Using a jeweler's scale for weighing the specimen is advisable. Should scalp hair be unavailable, a comparable amount of body hair can be used. When mentioning head hair, it specifically means scalp hair. Body hair encompasses all other varieties of hair (like facial or axillary hair).

Process Overview

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

Accessioning pertains to the initial integration of a sample into a laboratory’s framework. This step verifies if the sample was properly sealed and dispatched, assigns an arbitrary LAN (Laboratory Accessioning Number), and finishes any outstanding data entry that an electronic chain of custody system doesn't cover.

Screening is a preliminary, rapid check for substances of abuse. It's a cost-efficient approach for excluding drug consumption in most samples; however, a positive result from screening requires confirmation before being legally admissible. Samples testing presumptively positive in Screening necessitate further confirmation.

Screens indicating a presumptive positive require additional hair to be extracted from the original sample for further analysis. During this Extraction phase, substances are isolated from hair at a significantly lower concentration level compared to other methods (such as urine or oral fluid testing), making hair drug screening the most challenging method to execute.

For any screening results testing positive, Confirmation is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with a presumptive positive status are cleansed prior to Confirmation, as necessary. Every stage, from Accessioning up to Confirmation, is examined through the CAP (College of American Pathologists) Hair designation and alignment with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for up to 90 days, contrary to urine tests which offer a more limited detection period.
• Manipulation resistance: Cheating a hair drug test is exceptionally challenging, enhancing the accuracy of the outcomes.
• Historical pattern provision: Hair drug testing offers an extended timeline of drug use, rather than merely identifying recent consumption.

Limitations:

• Incapable of identifying recent consumption: Detection in hair requires around 5-7 days after drug use.
• Expense: Hair drug tests tend to be pricier compared to alternate drug testing methods.
• Result variations: Factors like hair color and individual differences in growth rates can influence the concentration of drug residues in the hair.

Note: The term "hair follicle test" is a misnomer, as the analysis targets the hair strand above the scalp, not the follicle beneath it.
