Hair Follicle Drug Testing - Calvin, IL

What it is, How it works

Hair analysis is now recognized as a significant method for identifying the use of alcohol and drugs. Hair captures a historical record of substance use by encapsulating biomarkers within its fibers as it grows. When taken from the scalp, a hair sample can reveal drug and alcohol use for up to three months. Hair collection is straightforward, relatively tamper-proof, and convenient for transport.

A 1.5-inch section consisting of around 200 hair strands (similar to the size of a #2 pencil) near the scalp can yield 100mg, which is the optimal amount for testing and verification purposes. For tests such as EtG and those exceeding 10 panels, a sample size of 150mg is advisable. It's recommended to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a comparable amount of body hair may be used. When referencing head hair, we specifically mean scalp hair, while body hair includes all other types (such as facial or axillary hair).

Process Overview

There are four primary steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the early stage of entering a sample into a lab's system. This includes ensuring the sample was appropriately sealed and sent, generating an unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not facilitated by an electronic system.

Screening involves a preliminary examination for substances of abuse. Although Screening provides a cost-efficient approach to exclude drug use in most cases, a positive result requires confirmation for legal proceedings. Any sample that is initially positive needs additional verification.

Should a sample test positive at the Screening stage, further hair from the primary sample is used for Extraction. Here, substances are extracted at a significantly lower concentration compared to other methods (such as urine or oral fluid), making hair drug testing the most challenging to execute.

Positive screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation if necessary. The whole lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can uncover substance use for up to 90 days, unlike urine tests, which have a shorter window.
• Hard to manipulate: Cheating a hair drug test is quite challenging, ensuring more reliable outcomes.
• Shows usage trends: It can reveal drug use patterns over time, rather than just recent intake.

Limitations:

• Doesn't detect recent intake: Drugs become detectable in hair around 5-7 days post-use.
• Expense: Hair drug testing generally costs more than other testing techniques.
• Result variance: Hair color and personal differences in growth can affect drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Calvin, IL outshines traditional urine testing methods in numerous ways. It offers superior detection accuracy by identifying substance use over a longer duration, effectively capturing ongoing usage.
