Hair Follicle Drug Testing - Humphrey, NE

What it is, How it works

Hair testing has emerged as a potent method for detecting drug and alcohol consumption. Hair serves as a retrospective archive of substance use by capturing biomarkers within the fibers of the hair as it grows. When collected near the scalp, it can provide a detection period of around 3 months for alcohol and drugs. This method of hair collection is straightforward, resistant to tampering, and easy for transport.

A hair sample measuring 1.5 inches, consisting of around 200 strands (comparable to the width of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the ideal volume for both initial screening and follow-up confirmation. For extensive tests like EtG, additional tests, and those exceeding 10 panels, we advise collecting 150mg. We suggest using a jeweler’s scale for precision in weighing. If scalp hair is not accessible, an equal amount of body hair may be sourced. By head hair, we mean specifically scalp hair, while body hair encompasses all other types like facial or axillary hair.

Process Overview

The laboratory processing of a drug test comprises four core stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating the specimen into the laboratory system. This step ensures that the specimen was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data not input by electronic chain of custody.

Screening is a preliminary procedure for the detection of illicit drugs. It is a cost-efficient technique for ruling out drug consumption in most cases, but a positive result needs subsequent confirmation for legal validation. Any samples that preliminarily test positive during Screening require further confirmation.

For samples that test presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction process. Here, drugs are isolated from hair at much lower concentrations compared to other methods (such as urine or saliva), which is why hair drug testing is notoriously challenging.

Confirmation of any positive result in Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS tests. All samples that are presumptive positive are thoroughly washed before confirmation if necessary. The complete process from Accessioning to Confirmation is conducted under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use for up to 90 days, unlike urine tests which offer a much shorter detection timeframe.
• High resistance to tampering: Cheating on a hair drug test is extremely difficult, thus ensuring more reliable results.
• Historical use pattern: It can outline an individual's drug use history over a longer period, not limited to recent use.

Limitations:

• Inability to detect recent use: Drugs typically become detectable in hair after around 5-7 days.
• Expense: Generally, hair drug tests are costlier compared to alternative drug testing methods.
• Result variability: Factors like hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: The term "hair follicle test" is commonly used; however, the analysis is performed on the hair strand and not the follicle beneath the scalp.
