Hair Follicle Drug Testing - Newcastle, OK

What it is, How it works

Hair testing is now recognized as a robust means for detecting alcohol and drug use. Hair captures a long-term record of substance use by embedding biomarkers in the fibers of the growing hair. When gathered from near the scalp, hair can offer a detection period of up to three months for drugs and alcohol. It is straightforward to collect, harder to tamper with, and simple to transport.

A sample measuring 1.5 inches from about 200 hair strands (approximating the size of a #2 pencil) close to the scalp provides 100mg of hair, an ideal amount for both screening and confirmation. For EtG extensions or tests beyond 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for accurate measurement. If scalp hair cannot be obtained, an equivalent amount of body hair is acceptable. In context, head hair refers strictly to scalp hair. Body hair includes all other types (such as facial and axillary hair).

Process Overview

The four key phases in processing a drug test result at the laboratory are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample within a laboratory’s system. This phase confirms the sample was properly sealed and dispatched, assigns it a random LAN (Laboratory Accessioning Number), and concludes any remaining data input absent from an electronic chain of custody system.

Screening performs a preliminary inspection for drugs of abuse. While it is a budget-friendly method for excluding drug use in most samples, a positive screen must be confirmed to be valid in legal settings. Samples that test presumptively positive during Screening must undergo further confirmation.

Should a sample test presumptively positive in Screening, more hair is extracted from the initial specimen and prepared for Extraction. This phase involves extracting drugs from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are utilized for confirming any positive Screening outcomes. All presumptive positive samples undergo washing prior to confirmation when necessary. The entire lab procedure from Accessioning to Confirmation is inspected under both CAP (College of American Pathologists) Hair criteria and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug use for up to 90 days, while urine tests have a shorter detection duration.
• Challenging to deceive: It is notably challenging to manipulate a hair drug test, enhancing result accuracy.
• Offers historical insight: It can demonstrate a drug use pattern over time, rather than just recent use.

Limitations:

• Inability to detect recent use: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically cost more than alternative drug testing methods.
• Result variability: Factors like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the test examines the hair strand and not the hair follicle beneath the scalp.
