For those in Cornell, Illinois seeking comprehensive hair follicle drug testing, turn to Accredited Drug Testing. Whether for drug or alcohol analysis, we specialize in hair-based testing and have centers nationwide, including every city, to administer these tests efficiently. Typically, hair samples gathered from the crown or body, provided they measure 1.5 to 2 inches, are used for drug, alcohol/ETG analysis, or tailored testing options.
Hair follicle drug testing has gained traction as a preferred method in recent times. It serves more than just employers with strict anti-drug policies but also plays crucial roles in judicial and rehabilitation sectors. With the ability to reveal drug usage over a span of up to 90 days, the hair drug test is invaluable in observed sampling and challenging to manipulate. Nevertheless, for recent usage within a 5-day window, urine tests remain the most precise option.

Hair testing is acknowledged as an effective method for identifying drug and alcohol use. It captures a long-term overview by preserving biomarkers within the fibers of the maturing hair strand. When sourced near the scalp, hair can reveal a detection timeframe of up to about 3 months for alcohol and drugs. Collecting hair is straightforward, it resists tampering, and is convenient for shipping.
A 1.5-inch segment consisting of approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, an optimal sample for diagnostics and confirmation. For EtG, ancillary tests, and/or panels exceeding ten, a 150mg sample is advisable. It's suggested to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. "Head hair" strictly denotes scalp hair, whereas "body hair" pertains to other hair categories (facial, axillary, etc.).
Process Overview
The principal stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary handling of a sample into the laboratory’s system. It involves confirming that the sample was sealed and transported accurately, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data input not furnished by an electronic chain of custody system.
Screening serves as a rapid initial check for substance abuse. While it proves a cost-efficient approach to eliminate drug usage in most cases, a positive screen must be verified to be valid in legal proceedings. Samples deemed presumptively positive during Screening require additional confirmation.
For samples that are presumptively positive during Screening, further hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are isolated from hair at a much reduced concentration than in other methods (such as urine or oral fluid), which is why hair drug screening is regarded as more challenging.
Positive screening results are validated through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Note: While commonly called "hair follicle tests", the procedure actually examines the hair strand and not the follicle beneath the scalp

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
