Hair Follicle Drug Testing - Toulon, IL

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption, providing a comprehensive history through biomarkers trapped in hair strands as they grow. When collected near the scalp, the hair can present a detection timeframe of up to roughly 90 days for alcohol and other drugs. Hair collection is straightforward, relatively tamper-proof, and convenient to send.

A 1.5-inch section of approximately 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp will yield 100mg, the optimal amount for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of hair is advisable. Using a jeweler’s scale for measuring the specimen is recommended. In cases where scalp hair is absent, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

There are four key steps in processing a drug test in a lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary entry of a sample into the laboratory's system, which includes checking that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any additional required data entry not covered by an electronic chain of custody system.

Screening is a rapid initial check for drugs of abuse. It is a cost-effective way to rule out drug usage for most cases, though a positive screening requires confirmation to be valid in legal settings. Presumptively positive samples in Screening necessitate a secondary confirmation.

For samples that are presumptively positive during Screening, additional hair is taken from the initial sample for Extraction. This involves extracting drugs from hair at lower concentrations than other methods (such as urine or oral fluids), making hair drug screening the most challenging method to conduct.

Confirmation of any positive screen result is completed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation if necessary. The whole lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug screenings can identify drug use for up to 90 days, unlike urine tests which have shorter detection periods.
• Difficult to falsify: Cheating a hair drug test is very challenging, making results more reliable.
• Offers historical insights: It can display a pattern of drug use over some time instead of just recent usage.

Limitations:

• Does not detect recent use: Detectability of drugs in hair takes about 5-7 days.
• Expense: Hair drug screenings generally cost more than other testing methods.
• Result variability: Factors like hair color and personal differences in hair growth can influence the levels of drug metabolites in the hair.

Note: While commonly referred to as "hair follicle tests", the analysis is conducted on the hair strand itself, not the follicle beneath the scalp.
