Hair Follicle Drug Testing - Pinewood, MN

What it is, How it works

Hair analysis has emerged as an influential approach for identifying drug and alcohol consumption. The hair captures a prolonged timeline of alcohol and drug usage by encasing biomarkers within the strands as they grow. When extracted near the scalp, hair offers a detection span of up to about three months for both alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.

A sample about 1.5 inches long with approximately 200 hair strands (equivalent to the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, add-ons, and/or tests more than 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for accurate weighing. If scalp hair is inaccessible, a similar volume of body hair can be acquired. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses other types such as facial and axillary hair.

Process Overview

There are four core stages in the laboratory evaluation of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a specimen into a lab’s network. This consists of ensuring that the sample was appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and inputting any additional data absent from an electronic chain of custody system.

Screening involves an initial rapid assessment for substances of abuse. While Screening serves as an economical method to dismiss drug usage in numerous samples, a positive screening must undergo confirmation to be legally valid. Any samples with a presumptive positive in Screening necessitate further confirmation.

If a sample shows a presumptive positive during the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. Here, drugs are isolated from hair at notably lower concentrations than other techniques (such as urine or oral fluid), making hair drug testing one of the most challenging methodologies to execute.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleaned prior to confirmation if required. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Challenge to manipulate: It is notably tough to deceive a hair drug test, enhancing result accuracy.
• Offers historical insights: It can reveal a pattern of drug consumption over time, not merely recent intake.

Limitations:

• Incapable of detecting recent use: It requires approximately 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Variability in outcomes: Factors such as hair color and individual discrepancies in hair growth can influence the levels of drug metabolites in hair.

Note: While commonly termed as "hair follicle tests", the test itself examines the hair strand rather than the follicle beneath the scalp.
