Hair Follicle Drug Testing - St. Joseph, MN

What it is, How it works

Hair analysis has gained recognition as a robust method for identifying drug and alcohol consumption. Hair captures a long-lasting record of alcohol and other drugs by encapsulating biomarkers within the structural elements of the growing hair. When hair is sourced near the scalp, it can offer up to a roughly 3-month detection timeframe for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch segment consisting of around 200 hairs (roughly the size of a #2 pencil) close to the scalp will yield 100mg of hair, which is the optimal quantity for testing and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a 150mg hair sample is advisable. We suggest weighing the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair can be used. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning involves the introductory processing of a sample into a lab’s system. This step encompasses ensuring the sample was sealed and transported correctly, designating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not provided via an electronic chain of custody system.

Screening serves as an initial quick evaluation for substances of abuse. While Screening provides a cost-efficient method to rule out drug use for the majority of samples, a positive SCREEN result must be confirmed to be court-eligible. All samples with a presumptive positive in Screening require a secondary confirmation procedure.

If Screening indicates a presumptive positive, more hair is taken from the original sample and made ready for Extraction. At this point, drugs are extracted from hair at significantly lower concentrations as compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is among the most complex methodologies.

Confirmation of any confirmed positive result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes a washing stage prior to confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can identify drug usage for up to 90 days, in contrast to urine tests with shorter detection windows.
• Challenging to manipulate: Cheating a hair drug test is highly difficult, enhancing the accuracy of the results.
• Offers historical insights: It can reveal a timeline of drug use over an extended period, beyond just recent usage.

Limitations:

• Unable to detect recent use: It requires 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to be costlier than other drug testing methods.
• Result variability: Elements such as hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

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