Hair Follicle Drug Testing - Clarysville, MD

What it is, How it works

Hair analysis has gained recognition as an effective means to identify drug and alcohol consumption. It offers an extended timeline of drug use by capturing biomarkers within the strands of hair as they grow. When collected near the scalp, hair can offer a detection period of up to roughly three months for substances like alcohol and drugs. Hair sampling is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch segment consisting of approximately 200 hair strands (equivalent to a #2 pencil's thickness) nearest to the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation processes. For EtG, supplementary tests, and/or panels exceeding 10, 150mg is advised. It is recommended to weigh the sample using a jeweler's scale. If head hair is not available, an equivalent quantity of body hair may be obtained. In our context, head hair strictly refers to scalp hair, while body hair encompasses all other types (like facial and axillary hair).

Process Overview

The laboratory processing of a drug test result encompasses four major stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially introduced into a laboratory’s system. This procedure includes ensuring the sample was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and entering any additional data not provided by an electronic chain of custody system.

Screening performs an initial check for drug abuse. Although Screening is economical for excluding drug usage in most samples, a positive screening must be confirmed for court admissibility. Samples with presumptive positive results in Screening require further confirmation.

If a sample shows presumptive positivity in Screening, additional hair is extracted from the initial specimen for Examination. In this step, drugs are derived from hair at much lower concentrations compared to other methods (like urine or oral fluids), highlighting the complexity of hair drug screening.

The Confirmation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug consumption over a span of up to 90 days, unlike urine tests which offer a shorter detection window.
• Challenging to manipulate: Tampering with hair drug tests is notably difficult, leading to more reliable results.
• Chronicles usage history: It depicts drug usage patterns over time, rather than just recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs appear in hair approximately 5-7 days after use.
• Expense: Hair drug tests are typically more costly compared to other drug testing techniques.
• Result inconsistency: Variables like hair color and individual hair growth can influence drug metabolite levels in hair.

Note: Though often termed as "hair follicle tests," these tests analyze the hair strand, not the hair follicle beneath the scalp.
