Hair Follicle Drug Testing - Lowell, NC

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair retains a historical record of substances through biomarkers trapped in the strands as they grow. When acquired near the scalp, hair can reveal drug and alcohol data spanning up to three months. It is straightforward to collect, challenging to tamper with, and easy to transport.

A 1.5-inch section consisting of roughly 200 strands near the scalp provides 100mg of hair, which is ideal for both screening and confirmation tests. For tests including EtG, add-ons, or over 10 panels, it is advised to collect 150mg. Utilizing a jeweler's scale is suggested for weighing the sample. If scalp hair isn't an option, a comparable quantity of body hair is acceptable. Head hair specifically refers to scalp hair, whereas body hair includes all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample is preliminarily processed into a lab’s system, ensuring that it was correctly sealed and sent, generating a random Laboratory Accessioning Number (LAN), and completing any supplemental data required beyond the electronic chain of custody system.

Screening is an initial rapid assessment for substance abuse. While being cost-efficient for excluding drug usage in most samples, a positive result in Screening requires confirmation to be valid in a legal setting. Samples presumed positive in Screening necessitate subsequent confirmation.

If a sample shows a presumptive positive result in Screening, additional hair is extracted from the initial sample for the Extraction procedure. In this step, drug concentration is derived from hair at a lower level relative to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.

Positive Screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as needed. The entire laboratory process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests reveal substance use up to 90 days, in contrast to the shorter span of urine tests.
• Cheating is difficult: The accuracy of hair drug tests is higher due to the challenge in falsifying results.
• Historical insights: It provides a usage pattern over time, rather than only recent activity.

Limitations:

• Doesn't detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug testing tends to be pricier than other testing forms.
• Result variability: Factors like hair color and individual growth rates can influence drug metabolite levels in hair.

Note: Although often called “hair follicle tests," the analysis targets the hair shaft, not the follicle beneath the scalp.
