Hair Follicle Drug Testing - K I Sawyer, MI

What it is, How it works

Hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair retains biomarkers of alcohol and drugs within its strands, offering a prolonged historical record. When gathered near the scalp, hair can reveal drug and alcohol use for up to around three months. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp will yield 100mg, which is the preferred sample size for screening and confirmation. For EtG, additional tests, and/or panel tests exceeding 10, 150mg of hair is advisable. We suggest measuring the sample using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair can be utilized. When discussing head hair, it specifically refers to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The key steps in the laboratory analysis of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory's framework. This step verifies that the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not already provided by an electronic chain of custody system.

Screening involves a preliminary inspection for drug abuse. Though Screening is an economical means to dismiss drug use in most samples, a positive result requires confirmation to be legally valid. Samples deemed presumptively positive in Screening need a secondary validation.

If Screening indicates a presumptive positive, additional hair is extracted from the main sample for Extraction. This phase extracts drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which contributes to hair drug testing being the most challenging method to conduct.

Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptively positive are cleansed before confirmation as necessary. The complete laboratory process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can uncover drug use for up to 90 days, unlike urine tests which have a shorter detection duration.
• Resistance to tampering: Hair drug tests are challenging to manipulate, ensuring more reliable results.
• Historical usage data: They provide a timeline of drug use over an interval, not just recent activity.

Limitations:

• Cannot identify recent consumption: Drugs become discernible in hair approximately 5-7 days after use.
• Expense: Hair drug tests often cost more than alternative drug testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can impact drug metabolite levels in hair.

Note: Despite being called "hair follicle tests," the test itself evaluates the hair strand rather than the follicle beneath the scalp.
