Hair Follicle Drug Testing - Bolivia, NC

What it is, How it works

Hair analysis has increasingly been recognized as an effective method for detecting drug and alcohol consumption. Hair captures a comprehensive history of substances by embedding biomarkers within the fibers of the elongated hair strand. When clipped near the scalp, hair can offer up to a 3-month detection span for alcohol and various drugs. Hair is straightforward to gather, somewhat challenging to tamper with, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp will yield 100mg, the optimal sample size for both screening and confirmation. For EtG, enhancements, and/or analyses exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to measure the sample. If scalp hair is absent, a comparable quantity of body hair may be collected. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The primary stages in the laboratory processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing of a sample into a laboratory's system. This encompasses verifying that the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not available through an electronic chain of custody system.

Screening involves an initial rapid examination for illicit substance use. Although Screening offers a cost-effective method to rule out drug intake in most samples, a positive screen requires confirmation to be valid in court. Any samples that are presumptively positive in Screening necessitate further confirmation.

If a sample tests presumptively positive during the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. During this phase, substances are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which renders hair drug analysis as one of the more challenging methodologies to execute.

Confirmation of any positive screening result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing prior to confirmation as required. The entire laboratory workflow from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair stipulation 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 with a shorter detection timespan.
• Challenge to deceive: It is exceedingly difficult to manipulate a hair drug test, thus enhancing result accuracy.
• Reveals historical patterns: It can reveal trends of drug use over a length of time, beyond just recent usage.

Limitations:

• Unable to detect recent use: It requires approximately 5-7 days for substances to become traceable in hair.
• Expense: Hair drug tests are typically costlier than other drug testing approaches.
• Result variability: Aspects like hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: Commonly termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp
