Hair Follicle Drug Testing - Chesterville, IL

What it is, How it works

Hair testing is now regarded as a significant resource for detecting drug and alcohol consumption. Hair captures biomarkers within the fibers of the growing strand, offering a long-term record of substance use. When specimens are taken close to the scalp, they can provide roughly a three-month detection window for both alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easily transportable.

A 1.5-inch segment comprising approximately 200 strands of hair (equivalent to a #2 pencil thickness) nearest the scalp yields 100mg, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a recommended 150mg of the specimen should be collected. We suggest utilizing a jeweler’s scale for weighing. If scalp hair is unavailable, a comparable quantity of body hair may be sourced. When we mention head hair, we refer solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample within the laboratory’s system. This process confirms that the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and concludes any supplemental data entry absent in an electronic chain of custody system.

Screening performs an initial rapid drug abuse check. While Screening provides a cost-efficient method to rule out drug usage in most samples, confirming a positive screen is necessary for it to be court-admissible. All samples that are tentatively positive in Screening do require further confirmation.

Should a sample show tentative positivity during the Screening phase, additional hair is extracted from the initial specimen for further preparation in Extraction. In this phase, drug extraction occurs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening particularly challenging to execute.

Confirmation for any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples are subject to washing prior to confirmation as applicable. The complete laboratory process, spanning from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation in accordance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests detect drug use for up to 90 days, contrasting with urine tests, which have a shorter detection window.
• Difficulty to cheat: It is exceptionally challenging to deceive a hair drug test, thus enhancing result accuracy.
• Provides historical data: It offers a comprehensive pattern of drug use over time, rather than merely recent use.

Limitations:

• Cannot detect recent use: Approximately 5-7 days are necessary before drugs become detectable in hair.
• Cost: Hair drug tests typically incur higher costs than other testing methodologies.
• Variations in results: Factors like hair color and individual differences in hair growth may influence the concentration of drug metabolites in hair.

Note: While commonly labeled as "hair follicle tests", the analysis concerns the hair strand rather than the follicle beneath the scalp
