Hair Follicle Drug Testing - Manchac, LA

What it is, How it works

The method of hair testing has gained acceptance as an effective means to identify drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by embedding biomarkers within the strands as they grow. A sample taken near the scalp can extend the detection period to roughly three months for both alcohol and drugs. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.

A sample measuring 1.5 inches long with approximately 200 strands (roughly the girth of a #2 pencil) located nearest to the scalp will yield 100mg, which is the optimal quantity for both screening and confirmatory tests. For EtG, additional tests, and/or panels exceeding 10, it is advised to collect 150mg. Using a jeweler's scale for specimen measurement is recommended. If scalp hair is not available, a comparable amount of body hair can be taken. It should be noted that head hair specifically refers to scalp hair alone, whereas body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The primary steps in the laboratory evaluation of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to initially processing a sample into a lab's tracking system. This step ensures the sample was correctly sealed and sent, allocates a unique LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry not submitted through an electronic custody system.

The Screening process provides a preliminary check for substances of abuse. Although Screening is an economical method to negate drug use in most cases, any positive findings require verification to be valid in legal proceedings. Samples that show presumptive positive results in Screening necessitate a follow-up confirmation.

In situations where a presumptive positive arises during Screening, the original sample undergoes additional hair extraction for further preparation in the Extraction stage. Here, drug components are separated from hair at much reduced concentrations than found in alternative approaches (such as urine or oral fluids), highlighting hair drug testing as the most challenging technique to execute.

The Confirmation phase for positive Screening results is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, all samples with presumptive positives undergo washing as required. The entire laboratory course from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of Hair Drug Testing:

• Extended detection period: Hair tests can identify drug usage for up to 90 days, unlike urine tests which offer a shorter timeframe.
• Hard to falsify: Hair drug tests are difficult to defeat, thereby enhancing the accuracy of the findings.
• Reflects usage trends: Capable of showing a consumption pattern over time, not merely recent activity.

Limitations:

• Inability to detect short-term use: Drugs typically become noticeable in hair after approximately 5-7 days.
• Expense: Hair testing is generally costlier compared to other drug testing options.
• Result variances: Differences in factors like hair color and personal hair growth rates can influence drug metabolite concentrations in hair.

Note: Commonly mislabeled as "hair follicle tests", these tests actually assess the hair strand and not the follicle beneath the scalp.
