Hair Follicle Drug Testing - Minden, LA

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol intake. The hair captures a comprehensive timeline of substances such as alcohol by embedding biomarkers in the strands of growing hair. If collected from near the scalp, hair testing offers up to a 3-month period for detecting alcohol and drug use. Hair samples are easy to acquire, challenging to tamper with, and convenient to transport.

An ideal sample consists of a 1.5-inch segment of approximately 200 strands of hair (roughly the girth of a #2 pencil) closest to the scalp, amounting to 100mg, suitable for screening and verification. For EtG, additional tests, or analyses exceeding 10 panels, a 150mg sample is preferred. It is advisable to measure the sample weight using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair can be gathered. Head hair specifically refers to scalp hair, while body hair encompasses other types such as facial or axillary hair.

Process Overview

The drug testing procedure in a laboratory comprises four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the commencement of processing a sample into the laboratory’s system. It involves checking the integrity and proper shipment of the sample, assigning it a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody.

Screening constitutes a preliminary assessment for illicit substances. While it is a cost-efficient method to dismiss drug use in most cases, a positive screen mandates confirmation for legal acceptability. Samples indicating a presumptive positive in Screening require further confirmation.

In instances of a presumptive positive during the Screening phase, additional hair is extracted from the initial sample for Extraction. This phase involves isolating drugs from hair at significantly lower concentrations in comparison to methods like urine or oral fluid analysis, contributing to the complexity of hair drug screening.

Confirmation of any positive findings from Screening is completed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as needed. Every step from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair certification and accredited under ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use over a period of up to 90 days, which surpasses the shorter detection window of urine tests.
• High integrity: Hair drug testing presents challenges for fraudulence, thereby assuring more reliable outcomes.
• Insightful historical record: Offers a timeline of substance use over an extended period, beyond recent consumption.

Limitations:

• Inability to detect recent intake: It requires about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing is generally costlier than alternative drug testing techniques.
• Result variability: Elements such as hair color and individual hair growth differences can influence the levels of drug metabolites present in the hair.

Note: Although often dubbed "hair follicle tests", the procedure examines the hair strand itself, not the underlying hair follicle.
