Hair Follicle Drug Testing - Calvert, MD

What it is, How it works

Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive history of substance use by encapsulating biomarkers within the strands as they grow. When clipped close to the scalp, hair can reveal usage history for up to around three months for alcohol and drugs. Its collection is straightforward, tampering is relatively challenging, and it is simple to send off for testing.

A 1.5-inch segment consisting of roughly 200 hair strands (comparable to the diameter of a #2 pencil) from nearest the scalp provides 100mg, which is an ideal amount for both screening and confirmation analyses. For EtG screenings, add-ons, and/or tests exceeding a 10-panel assessment, a 150mg sample is advisable. It's suggested to measure the sample's weight with a jeweler's scale. If scalp hair cannot be obtained, body hair of the same volume may be used. "Head hair" pertains exclusively to scalp hair; "body hair" includes all other types (facial, underarm, etc.).

Process Overview

The laboratory examination of a drug test sample mainly involves four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process of integrating a sample into a lab's system initially. This step involves checking that the sample is appropriately sealed and transported, assigning it a LAN (Laboratory Accessioning Number), and performing any additional data entry not covered by an electronic chain of custody mechanism.

Screening serves as a preliminary, swift inspection for drugs. This determines basic drug presence, offering cost-effective preliminary information. Any screening that indicates a potential drug presence requires further verification to be used legally. Thus, samples shown as possibly positive must undergo secondary confirmation.

In instances where a sample evidences a presumptive positive from Screening, additional hair is taken from the original specimen for the Extraction phase. Here, substances are separated from hair at notably lower concentrations compared to alternative methods (e.g., urine or oral fluid), enhancing the complexity of hair drug screening.

Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, each sample noted as presumed positive undergoes a washing procedure if necessary. The complete process from Accessioning to Confirmation undergoes scrutiny as per both CAP (College of American Pathologists) Hair designation criteria and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the capability to identify drug usage for up to 90 days, as opposed to urine tests which operate within a shorter timeframe.
• Resistance to manipulation: Cheating a hair drug test is extremely tough, yielding more reliable outcomes.
• Offers usage patterns: This method can trace drug usage trends over time, unlike tests that reveal only recent consumption.

Limitations:

• Inability to identify recent use: A time lapse of roughly 5-7 days is needed for hair to exhibit drug traces.
• Expense: Hair drug tests are typically costlier than other kinds of drug screening processes.
• Variability in outcomes: Individual differences such as hair color and personal hair growth rates can impact drug metabolite concentrations found in the hair.

Note: Although frequently termed as "hair follicle tests", this analysis evaluates the hair strand itself, excluding the follicle beneath the scalp.
