Hair Follicle Drug Testing - Charlack, MO

What it is, How it works

Hair analysis has emerged as an effective resource for identifying drug and alcohol consumption. Hair offers a prolonged timeline of alcohol and drug use by capturing biomarkers in the fibers of the expanding hair strand. When obtained near the scalp, hair can offer up to roughly a 3-month window for detecting alcohol and other drugs. Hair is straightforward to gather, somewhat challenging to tamper with, and simple to send.

A typical sample of 1.5 inches comprising around 200 strands of hair (about the size of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal sample for initial screening and confirmation. For EtG, add-ons, and/or panels exceeding 10, a 150mg specimen is suggested. We suggest measuring the specimen using a jeweler’s scale. If scalp hair is not available, collecting an equal quantity of body hair is acceptable. When mentioning head hair, we are specifically referring to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The primary steps engaged in the lab processing of a drug testing result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a sample into a lab’s system. This process covers verifying that the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not handled by an electronic chain of custody system.

Screening involves a quick preliminary check for drugs of abuse. While Screening is a cost-efficient method to exclude drug use in most samples, a positive screen requires confirmation to be valid in court. Any samples that are presumptively positive in Screening require secondary confirmation.

If a sample is presumptively positive at the Screening phase, more hair is sourced from the initial specimen and prepped for Extraction. During this phase, drugs are extracted from the hair at a much lower concentration than in other methods (e.g., urine or oral fluid), explaining why hair drug screening is the most challenging method to execute.

Confirmation of any positive screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Challenging to falsify: Tampering with a hair drug test is very difficult, rendering the results more reliable.
• Offers historical insight: It can provide an overview of drug use patterns over an extended timeframe, not only recent activities.

Limitations:

• Inability to detect recent use: Drugs typically become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are generally pricier than other drug testing approaches.
• Outcome variations: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly termed "hair follicle tests", the test in fact analyzes the hair strand rather than the follicle below the scalp.
