Hair Follicle Drug Testing - University Park, IL

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair locks in biomarkers within the strands as they grow, allowing for a comprehensive timeline of usage. By sampling hair near the scalp, one can achieve a detection timeframe of up to about three months for substances like alcohol and other drugs. The collection of hair is straightforward, poses challenges to tampering, and can be easily sent for analysis.

A sample measuring 1.5 inches that includes around 200 hair strands (approximately equivalent to the thickness of a #2 pencil) from near the scalp will yield 100mg of hair, which is ideal for both initial tests and confirmatory analysis. For tests involving EtG, add-ons, or panels exceeding ten, a sample of 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair is acceptable. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The primary stages in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial steps of integrating a sample into the lab's system. This includes confirming the proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing additional data entries not covered by an electronic chain of custody system.

Screening conducts an initial assessment for substances of abuse. Though Screening is a cost-efficient strategy to exclude drug use in most samples, a positive screen needs further validation for court acceptance. Any samples deemed presumptively positive from the Screening require subsequent confirmation.

If a sample appears positive at the Screening phase, additional hair is taken from the original sample and readied for Extraction. In this step, compounds are withdrawn from the hair at concentrations far lower than other methods like urine or oral fluid testing, making hair drug analysis particularly challenging.

Confirmation of any positive screening outcome occurs using GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing presumptive positive results are cleansed before confirmation if needed. The whole lab operation from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug trials can identify drug use spanning up to 90 days, whereas urine tests have a more limited detection period.
• Hard to falsify: Cheating a hair drug test is quite challenging, ensuring more reliable results.
• Offers historical insights: It can present a drug use pattern over time, rather than merely indicating recent usage.

Limitations:

• Inability to identify recent use: It requires approximately 5-7 days for substances to become identifiable in hair.
• Expense: Generally, hair drug tests are pricier compared to alternative testing methods.
• Result variability: Aspects like hair color and individual hair growth differences can impact the concentration of drug metabolites in the hair.

Note: Though typically referred to as "hair follicle tests", the analysis focuses on the hair strand itself and not the follicle beneath the scalp.
