Hair Follicle Drug Testing - Stockton, MN

What it is, How it works

Hair testing has gained recognition as an effective means for identifying drug and alcohol use. Hair captures long-term evidence of substances by trapping biomarkers within the fibers as the hair grows. When gathered close to the scalp, hair offers a detection window of up to roughly three months for drugs and alcohol. Its collection is straightforward, with minimal risk of tampering, and is convenient for transportation.

A 1.5-inch segment of approximately 200 hairs (about the thickness of a #2 pencil) near the scalp will yield 100mg, the optimal amount for testing and validation. For EtG, additional tests, or tests exceeding 10 panels, a specimen size of 150mg is suggested. We advise using a jeweler’s scale to weigh the sample. If head hair is unavailable, a comparable amount of body hair can be utilized. References to head hair pertain exclusively to scalp hair, whereas body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The four primary steps in a laboratory's drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step that integrates a sample into the laboratory's system. This step verifies the sample's secure transportation, allocates a random LAN (Laboratory Accessioning Number), and completes any requisite data entry absent from an electronic chain of custody system.

Screening serves as an initial quick evaluation for substance use. As a cost-effective method, Screening can exclude drug use for the majority of samples. A positive result in Screening, however, requires further validation for any legal proceedings. Samples that show a presumptive positive in Screening necessitate secondary Confirmation.

If a sample shows a presumptive positive at the Screening phase, additional hair is taken from the original sample and readied for Extraction, where drugs are isolated from hair at much lower concentrations than found in other methods (e.g., urine or oral fluids). This challenge makes hair drug screening the most difficult method to conduct.

Confirmation for any positive screening outcomes uses GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before Confirmation as necessary. The entire laboratory process, from Accessioning to Confirmation, is evaluated 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 assessments can highlight drug usage for up to 90 days, unlike urine tests, which have a shorter assessment period.
• Hard to compromise: Cheating a hair drug test is exceedingly difficult, enhancing result accuracy.
• Charts historical use: It can outline a pattern of drug use over an extended time, not merely recent intake.

Limitations:

• Cannot determine recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug assessments typically incur higher costs compared to other testing techniques.
• Result variability: Factors like hair color and personal hair growth rates can influence drug metabolite concentrations in hair.

Note: Though termed "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle beneath the scalp.
