Hair Follicle Drug Testing - Bedford, NH

What it is, How it works

Hair analysis is now viewed as an impactful method for identifying drug and alcohol consumption. Hair captures a lasting record of drug and alcohol use by retaining biomarkers within the hair strand as it grows. When cut near the scalp, hair can offer nearly a 3-month period of detection for drugs and alcohol. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.

A hair sample measuring 1.5 inches and comprising approximately 200 strands (about the thickness of a #2 pencil) close to the scalp yields 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advised. It is recommended to measure the sample on a jeweler’s scale. If scalp hair cannot be obtained, a corresponding quantity of body hair may be used. When we mention head hair, we specifically mean scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The key stages in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample within a lab’s system. This step verifies that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not provided by an electronic chain of custody system.

Screening is a preliminary review for substances of abuse. While Screening is a cost-efficient approach to discard drug use in the majority of samples, a positive screen requires confirmation to be valid in legal settings. Samples identified as presumptively positive in Screening must undergo further confirmation.

In the event of a presumptively positive result during Screening, additional hair is extracted from the original sample to perform Extraction. In this phase, drugs are extracted from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging method to conduct.

Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all presumptive positives are cleaned as needed. The comprehensive laboratory process from Accessioning to Confirmation is reviewed in compliance with both the CAP (College of American Pathologists) Hair designation and accreditation standards of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage for up to 90 days, in comparison to urine tests that have a shorter detection period.
• Challenging to deceive: Cheating a hair drug test is extremely difficult, thereby increasing result accuracy.
• Offers historical insight: It provides insights into patterns of drug use over time, beyond just recent use.

Limitations:

• Inability to detect recent use: It takes around 5-7 days for drugs to appear in hair samples.
• Expense: Hair drug tests typically incur higher costs than other drug testing methods.
• Result variability: Elements like hair color and personal variations in hair growth can alter the presence of drug metabolites.

Note: Although often termed "hair follicle tests", the evaluation involves the hair strand and not the follicle beneath the scalp.
