Hair Follicle Drug Testing - Dougherty, OK

What it is, How it works

Hair testing is recognized as an effective mechanism for identifying both drug and alcohol usage. Hair captures a prolonged record of these substances by ensnaring biomarkers within the fiber structure of the hair strand as it grows. Sampling hair close to the scalp can offer a detection timeline of roughly three months for alcohol and drugs. Collecting hair is straightforward, it is somewhat hard to tamper with, and it's convenient for transportation.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (equivalent to a #2 pencil's circumference) nearest to the scalp, will yield 100mg of hair, which is the prime quantity for screening and verification. For EtG, additional checks, and/or tests surpassing 10 panels, it's advisable to have 150mg of the specimen. Using a jeweler’s scale for weighing the specimen is recommended. If scalp hair cannot be provided, a comparable volume of body hair can be collected. By head hair, we refer solely to scalp hair. All other types of hair (facial, axillary, etc.) are categorized as body hair.

Process Overview

The core procedures involved in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary processing of the sample into a laboratory's records. This step involves ensuring the sample's seal and transport were properly executed, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any additional data entry missing from an electronic chain of custody system.

Screening provides an initial cursory assessment for drugs of abuse. Screening offers a cost-efficient method to exclude drug usage in most samples, though a positive screen must be verified to uphold in legal settings. Samples that yield a presumptive positive in Screening necessitate further confirmation.

Should a sample test presumptive positive during Screening, additional hair is extracted from the initial specimen and prepped for Extraction. In this phase, drugs are drawn from the hair at considerably lower concentrations than seen in other techniques (such as urine or oral fluid), making hair drug screening a more challenging methodology to administer.

Confirmation of any positive screen result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation as required. From Accessioning to Confirmation, the entire lab process is conducted under both the CAP (College of American Pathologists) Hair designation and adheres to the accreditation standards of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, whereas urine tests only cover a shorter period.
• Hard to manipulate: Manipulating a hair drug test is notably challenging, enhancing the accuracy of results.
• Delivers historical insights: It offers a chronology of drug usage over time, not just recent activity.

Limitations:

• Not suitable for recent consumption: Drugs typically become detectable in hair around 5-7 days post-use.
• Expense: Hair drug tests tend to be pricier than alternative drug testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Though often termed as "hair follicle tests", the actual analysis is performed on the hair strand itself, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing
