Hair Follicle Drug Testing - Biscoe, NC

What it is, How it works

Through its comprehensive analysis, hair testing has emerged as an effective means to identify drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by encapsulating biomarkers within the strands' fibers as they grow. By gathering samples near the scalp, the process offers an approximate three-month detection period for substances. The collection of hair proves to be straightforward, challenging to tamper with, and convenient to transport.

Obtaining a 1.5-inch snippet comprising roughly 200 hair strands (comparable to a #2 pencil) from the scalp yields 100mg, the optimal quantity for both initial screenings and confirming results. For EtG add-ons or tests surpassing 10 panels, a 150mg sample is advisable. It is recommended to weigh the sample using a jeweler’s scale. In situations where scalp hair is absent, a comparable amount of body hair may be procured. The term head hair specifically denotes scalp hair, whereas body hair encompasses other types (such as facial or axillary hair).

Process Overview

The laboratory processing of drug test results encompasses four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, samples undergo initial processing within the lab's system. This involves confirming that the sample is properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and addressing any supplemental data entry not covered by an electronic chain of custody.

Screening entails a preliminary assessment for drugs of abuse. While it serves as a cost-efficient initial analysis for the majority of samples, a positive screening result necessitates confirmation to uphold its validity in legal contexts. Samples exhibiting presumptive positive results during Screening require added confirmation.

Should a sample yield a presumptive positive during Screening, additional hair is drawn from the collected specimen for Extraction. At this stage, drug substances are extracted from hair at concentrations significantly lower than alternative methods (such as urine or oral fluid). This renders hair drug screening one of the most complex testing methodologies.

To affirm a positive screening outcome, Confirmation is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that indicate presumptive positivity are cleaned pre-confirmation, if needed. The comprehensive laboratory sequence from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair certification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection time: Hair drug testing identifies drug use for up to 90 days, unlike urine tests which offer a more limited detection period.
• Resistance to manipulation: Hair drug tests are notably challenging to falsify, resulting in more precise outcomes.
• Historical insight: This method reveals patterns in drug usage over extended durations, rather than solely indicating recent consumption.

Limitations:

• Limited immediate detection: Drugs require about 5-7 days to become detectable within hair samples.
• Expense: Hair drug testing typically incurs higher costs compared to other methods.
• Result variability: Elements such as hair pigmentation and personal differences in growth rates can influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the analysis actually focuses on the hair strand itself, rather than the follicle beneath the scalp.
