Hair Follicle Drug Testing - Hockessin, DE

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair preserves a historical record of substance use by embedding biomarkers within the strands as they develop. When sampled near the scalp, it can reveal drug and alcohol use for a duration of up to around three months. This method offers ease of collection, challenges in tampering, and straightforward transportation.

A sample of hair measuring 1.5 inches, consisting of roughly 200 strands akin to the thickness of a #2 pencil, provides 100mg, which is the optimal quantity for analysis and confirmation. For EtG, additional tests, or those extending beyond 10 panels, 150mg of hair is advised. It is suggested to measure the hair sample using a jeweler’s scale. If head hair cannot be obtained, an equivalent quantity of body hair may be used. The term head hair specifically refers to hair from the scalp, whereas body hair encompasses all other types (such as facial, armpits, etc.).

Process Overview

The process for handling a drug test in a lab includes Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample is logged into a laboratory’s system. This entails ensuring the sample is intact and properly shipped, assigning it a unique LAN (Laboratory Accessioning Number), and entering any additional data not captured by an electronic chain of custody system.

Screening is a preliminary assessment to identify drugs of concern. While cost-effective for ruling out drug use in most samples, a positive result from Screening must be validated to be legally acceptable. Any samples that test positive presumptively in Screening need further confirmation.

When a sample tests positive in the Screening phase, additional hair is taken from the initial collection to prepare for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations than with other methods such as urine or oral fluid, making it the most challenging drug screening methodology.

Positive results from Screening are verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed prior to confirmation if necessary. The full procedure, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair classification and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug consumption for up to three months, providing a longer window than urine tests.
• Difficult to tamper with: Cheating a hair drug test is challenging, leading to more reliable outcomes.
• Offers usage patterns: It delivers a timeline of drug usage rather than just recent activity.

Limitations:

• Cannot identify recent usage: Drugs are not detectable in hair until around five to seven days after use.
• Expense: Hair drug testing generally incurs higher costs compared to other testing methods.
• Result variances: Factors like hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", the analysis evaluates the hair strand itself, not the follicle beneath the scalp.
