Hair Follicle Drug Testing - Jamesville, NC

What it is, How it works

Hair testing is recognized as an effective resource for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and other substance use by embedding biomarkers within the structure of the growing hair strand. When sourced from near the scalp, hair can offer a detection period of up to 3 months for substances like alcohol and other drugs. Collecting hair is straightforward, less prone to tampering, and easy to transport.

A 1.5-inch section consisting of around 200 hair strands (approximately the girth of a #2 pencil) closest to the scalp will provide 100mg of hair, which is regarded as the optimal sample size for both screening and confirmation. For tests such as EtG add-ons and those exceeding 10 panels, a 150mg sample is advised. It's suggested to measure the sample using a jeweler's scale. If scalp hair cannot be obtained, a similar quantity of body hair can be used. References to head hair specifically mean scalp hair. Body hair includes all other hair types (e.g., facial, axillary).

Process Overview

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

During Accessioning, the sample is initially incorporated into the lab's system. This step confirms that the sample was correctly sealed and sent, allocates a unique LAN (Laboratory Accessioning Number), and finalizes any missing data entry not covered by an electronic chain of custody system.

Screening is a preliminary assessment for drug abuse. While it's cost-efficient for ruling out drugs in most cases, a positive screen must be verified for court acceptability. Samples showing presumptive positives in Screening require subsequent confirmation.

If a sample shows presumptive positivity in Screening, additional hair is retrieved from the original specimen for Extraction. During Extraction, drugs are isolated from hair at concentrations much lower than those seen in alternative methods (e.g., urine or oral fluids), making hair drug screening a challenging technique to execute.

Confirmation of positive screening outcomes is done through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positives undergo washing prior to confirmation as necessary. The overall laboratory workflow from Accessioning to Confirmation is overseen per both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a 90-day duration, contrasting with the shorter detection window seen in urine tests.
• Hard to manipulate: Cheating on hair drug tests proves quite challenging, enhancing the accuracy of the outcomes.
• Historical use insight: Hair tests can show a pattern of drug intake over time, as opposed to just recent consumption.

Limitations:

• Inability to detect current use: Generally, it takes around 5-7 days for drugs to manifest in hair.
• Expense: Hair drug screenings tend to be pricier compared to other drug testing methods.
• Result variability: Differences such as hair color and individual hair growth rates can influence drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the procedure actually examines the hair strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Jamesville, NC, when comparing hair follicle and urine tests, hair testing consistently demonstrates superior detection accuracy and reliability. Hair tests cover a more extended period, often up to 90 days, unlike urine tests which may fail to identify longer-term substance use.
