Hair Follicle Drug Testing - Exell, TX

What it is, How it works

Regarded as an effective method, hair testing is used for identifying alcohol and drug consumption. Hair encapsulates a long-term record of drug and alcohol intake by capturing biomarkers within the hair's fibers as it grows. When taken near the scalp, hair can reveal drug and alcohol usage for up to roughly three months. Hair is easy to gather, hard to tamper with, and straightforward to transport.

A sample measuring 1.5 inches, consisting of about 200 hairs (similar in thickness to a #2 pencil) nearest the scalp, yields 100mg of hair, which is the optimal amount required for analysis and verification. For EtG, additional tests, or tests exceeding 10 panels, a sample size of 150mg is advised. It is suggested to weigh the hair sample using a jeweler’s scale. If head hair is not available, an equivalent amount of body hair can be used. The term head hair refers solely to scalp hair. Body hair encompasses all other types of hair (e.g., facial, axillary).

Process Overview

In the lab processing of a drug test, the four key phases are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is introduced into a laboratory’s system. This step includes ensuring the sample was sealed and transported correctly, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any missing data entry not supplied by an electronic chain of custody system.

Screening involves conducting an initial test to check for drugs of abuse. Although Screening is an economical way to clear most samples of drug use, a positive screening result must be confirmed to be valid in court. Any samples that screen positive presumptively need to be confirmed with a secondary test.

In cases where a sample is presumptively positive at the Screening stage, additional hair is extracted from the original sample for the Extraction process. Here, drugs are separated from hair at a minute concentration compared to other methods (e.g., urine or saliva tests), which is why hair drug testing is considered the most challenging method.

GC/MS, GC/MS/MS, or LC/MS/MS are used to confirm any positive screens. All samples that are presumptive positives are cleaned as necessary prior to confirmation. The comprehensive lab procedure from Accessioning to Confirmation is reviewed under both the College of American Pathologists' Hair guidelines and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection: Hair drug tests extend detection up to 90 days, unlike urine tests, which have a shorter range.
• Hard to evade: Cheating a hair drug test is extremely challenging, leading to more reliable results.
• Captures history: It presents a usage pattern over a timeframe, not limited to recent intake.

Limitations:

• Doesn't reveal recent use: It takes around 5-7 days for drugs to become apparent in hair.
• Price: Hair drug tests typically incur higher costs than other testing methods.
• Result variations: Factors like hair color and personal hair growth rates can influence the concentration of drug metabolites in hair.

Note: Despite being called "hair follicle tests", the test examines the hair strand rather than the follicle beneath the scalp.
