Hair Follicle Drug Testing - Mccamey, TX

What it is, How it works

Hair analysis has become a formidable means for identifying substance and alcohol consumption. Hair offers an extended timeline of alcohol and drug presence by encapsulating markers in the strands as the hair grows. Captured near the scalp, hair can reveal a detection span of up to three months for alcohol and other drugs. Hair collection is straightforward, relatively difficult to tamper with, and simple to transport.

A 1.5-inch fragment of roughly 200 hair strands (akin to the thickness of a #2 pencil) taken closest to the scalp yields 100mg of hair, which is optimal for both initial and confirmatory testing. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is suggested. It is advisable to determine the sample weight using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent quantity of body hair can be utilized. When mentioning head hair, this exclusively pertains to scalp hair. Body hair includes all other types (such as facial, underarm, etc.).

Process Overview

The key procedures in the laboratory processing of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the primary processing of a sample within a lab’s framework. This procedure verifies that the sample is appropriately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data inputs not offered by an electronic chain of custody system.

Screening performs an initial rapid assessment for potential drug use. While it is an economical approach to ascertain drug absence in most samples, a confirmed result is necessary for legal acceptability. Any samples that yield presumptive positive results during Screening require further confirmation.

When a sample shows a presumptive positive outcome in the Screening phase, additional hair is taken from the original sample for Extraction. Here, drugs are isolated from the hair in concentrations much lower compared to other methods (e.g., urine or saliva), thereby making hair drug testing the most complex methodology to implement.

The Confirmation of any positive findings from Screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo washing before Confirmation as warranted. The complete laboratory sequence from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify substance usage for up to 90 days, unlike urine tests with much shorter detection periods.
• Challenging to manipulate: Hair drug tests are notably hard to falsify, thus enhancing result reliability.
• Historical data provision: This method offers a comprehensive view of substance use over time, rather than just detecting recent use.

Drawbacks:

• Inability to identify recent use: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair drug testing tends to be pricier than alternative testing methods.
• Result variability: Variations in hair color or personal hair growth rates can influence the drug metabolite concentration in hair samples.

Note: Despite the common term "hair follicle tests", this testing actually analyzes the hair strand, not the follicle from under the scalp.
