Hair Follicle Drug Testing - Anna, TX

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. It offers a long-term insight into alcohol and drug use by capturing biomarkers within the strands of growing hair. When hair samples are taken from the region closest to the scalp, they can provide a detection timeframe of up to roughly three months for both alcohol and drugs. The collection of hair samples is straightforward, has a low susceptibility to tampering, and can be transported with ease.

A sample measuring 1.5 inches consisting of about 200 hair strands (comparable to the width of a #2 pencil) near the scalp will yield 100mg of hair, which is the optimal quantity for both screening and confirming results. For EtG testing, additional panels, or tests exceeding 10, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is suggested. Should scalp hair be unavailable, a similar quantity of body hair may be obtained. The term head hair specifically refers to hair from the scalp, while body hair encompasses other types (such as facial or axillary hair).

Process Overview

The laboratory process for drug testing involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of integrating a sample into a lab’s system. This step includes ensuring the sample is properly sealed and delivered, assigning a random Laboratory Accessioning Number (LAN), and entering any extra data not captured by an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. Although Screening is an economical means to exclude drug use in most samples, any positive result during this stage must be confirmed to be valid for legal purposes. Specimens identified as having possible positive findings in Screening necessitate further confirmation.

For specimens indicating a possible positive in the Screening step, additional hair is extracted from the original sample and prepped for Extraction. In this phase, drugs are isolated from hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug testing the most complex method to implement.

Confirmatory analysis of any positive Screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all samples presumed positive undergo necessary washing. The entire laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug usage for up to 90 days, whereas urine tests have a shorter time frame.
• Challenging to deceive: It is highly challenging to manipulate a hair drug test, resulting in more reliable outcomes.
• Provides historical perspective: It can depict a pattern of drug use over time, rather than just recent usage.

Limitations:

• Inability to identify recent use: Drugs usually become detectable in hair only after about 5-7 days.
• Cost considerations: Hair drug tests tend to be pricier than other drug testing methods.
• Inconsistent findings: Elements like hair color and individual differences in hair growth can influence metabolite concentrations in the hair.

Note: Often labeled as "hair follicle tests", the procedure actually examines the hair strand rather than the follicle beneath the scalp.
