Hair Follicle Drug Testing - St. Joseph, LA

What it is, How it works

Hair analysis is increasingly recognized as an effective means for identifying substance use. Hair strands preserve a long-term record of drugs and alcohol by embedding biomarkers within the forming hair fiber. When cut near the scalp, hair samples offer a detection timeframe of roughly 3 months for substances. Collecting hair is straightforward, moderately resistant to tampering, and simple to transport.

A 1.5-inch portion comprising roughly 200 hair strands (akin to the girth of a #2 pencil) taken nearest the scalp yields 100mg, which is the optimal quantity for analysis. For EtG, additional tests, or panels exceeding 10, a specimen weighing 150mg is advisable. It’s suggested to measure the sample using a jeweler's scale. Should scalp hair be absent, a corresponding amount of body hair can be used. 'Head hair' specifies only scalp hair, while 'body hair' encompasses all other types (including facial, underarm, etc.).

Process Overview

The primary stages in lab processing of drug tests encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the sample's initial integration into a lab’s database. This process confirms the sample's secure sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any supplementary data not inputted by an electronic chain of custody protocol.

Screening performs an initial evaluation for abused substances. Although cost-efficient for excluding drug use in most samples, any positive findings in Screening must be validated to be legally acceptable. Presumptive positives in screening necessitate further verification.

When a sample tests presumptively positive during Screening, additional hair is needed from the original sample for the Extraction phase. Here, substances are extracted from hair at a noticeably reduced concentration compared to other methods (such as urine or saliva), making hair screening particularly challenging to conduct.

Verification of any positive screens is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that test presumptively positive undergo washing before confirmation if required. The complete lab procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use over a 90-day span in contrast to urine tests, which have a more limited detection period.
• Challenging to manipulate: Tampering with a hair drug test is notably difficult, thus increasing result reliability.
• Offers data over time: It provides insights into drug use trends over time, beyond just immediate usage.

Limitations:

• Inability to detect recent use: Drugs require about 5-7 days to become traceable in hair.
• Expense: Hair drug testing typically incurs greater costs than other testing methods.
• Result variability: Factors including hair color and individual hair growth rates can alter drug metabolite concentrations.

Note: Despite being commonly termed as "hair follicle tests", the procedure analyzes the actual hair strand and not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing
