Hair Follicle Drug Testing - Diaz, AR

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair stores a comprehensive record of alcohol and substance use by embedding markers within the hair strand's fibers as it grows. When obtained near the scalp, it can provide around a 3-month window for detecting alcohol and drugs. Hair is easy to collect, relatively tamper-resistant, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred sample size for testing and validation. For EtG, additional substances, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It is advisable to measure the sample's weight using a jeweler’s scale. If scalp hair cannot be acquired, a similar quantity of body hair may be obtained. References to head hair pertain exclusively to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The lab procedure for processing a drug test outcome consists of four chief steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary handling of a sample within a lab’s system. It includes verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not supplied by an electronic chain of custody system.

Screening undertakes an initial rapid examination for drug abuse. Although Screening offers a cost-efficient means to exclude drug usage in most samples, any positive screen must be verified to be allowable in court proceedings. Samples that are provisionally positive in Screening necessitate a follow-up confirmation.

Should a sample test provisionally positive during Screening, extra hair is taken from the initial sample and prepared for Extraction. Here, drugs are isolated from hair at a much lower concentration than alternative techniques (e.g. urine or oral fluid), rendering hair drug screening the most challenging method to execute.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive are washed before confirmation as required. The complete lab process from Accessioning through Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection window: Hair drug examinations can identify drug use for up to 90 days, in contrast to urine exams that have a narrower detection window.
• Hard to falsify: It is exceedingly challenging to tamper with a hair drug assay, thus making the findings more precise.
• Offers historical insight: It can reveal a pattern of drug intake over time, not merely recent usage.

Limitations:

• Incapable of detecting recent use: It takes about 5-7 days for substances to become noticeable in hair.
• Expense: Hair drug assays generally incur higher costs compared to other drug testing techniques.
• Result variability: Elements such as hair color and individual discrepancies in hair growth may influence drug metabolite concentrations in hair.

Note: Although frequently termed "hair follicle tests," the examination evaluates the hair strand itself and not the scalp's hair follicle.
