Hair Follicle Drug Testing - Neligh, NE

What it is, How it works

Hair testing is regarded as an effective method for detecting drug and alcohol intake. Hair captures a comprehensive history of substance use by embedding biomarkers within the fibers of the hair as it grows. When hair is taken from near the scalp, it can provide a detection window of up to three months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.

A sample measuring 1.5 inches, approximately 200 hair strands (similar to the thickness of a #2 pencil), closest to the scalp yields 100mg of hair, which is the preferred amount for analysis and verification. For testing such as EtG, add-ons, and panels beyond 10, a 150mg sample is advised. It's advisable to use a jeweler’s scale for weighing the sample. If scalp hair is not an option, a similar quantity of body hair can be used. References to head hair specifically mean scalp hair, whereas body hair encompasses all other types (such as facial or axillary hair).

Process Overview

There are four primary stages in lab processing for a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of incorporating a sample into the laboratory’s database. This step involves verifying the correct sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing additional data entry if the electronic chain of custody system lacks it.

Screening is a preliminary assessment aimed at detecting substances of abuse. Though Screening is an economical method for excluding drug use in most specimens, a positive result requires confirmation to be valid in legal proceedings. Samples with presumptively positive results during Screening necessitate a follow-up confirmation.

In cases of presumptive positivity in the Screening phase, further hair is extracted from the original sample and prepared for Extraction. During this phase, substances are extracted from hair in lower concentrations compared to other methodologies (like urine or oral fluid), highlighting hair drug testing as the most challenging methodology to execute.

Any positive findings from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that presumptively test positive are washed before confirmation, as necessary. The complete laboratory process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, compared to the shorter window for urine tests.
• Harder to manipulate: Manipulating a hair drug test is challenging, ensuring more precise results.
• Tracks usage history: It reveals a pattern of drug use over time, not just recent consumption.

Limitations:

• Unable to identify recent usage: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair tests are usually costlier than other drug-testing methods.
• Variation in outcomes: Factors like hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Though frequently termed "hair follicle tests", the analysis is conducted on the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
