Hair Follicle Drug Testing - Chappell, NE

What it is, How it works

Hair testing has emerged as a robust approach for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair strand, hair serves as a repository offering a comprehensive history of alcohol and drug use. When taken near the scalp, it can afford approximately a three-month detection timeframe for alcohol and drugs. Collection is straightforward, tampering is quite challenging, and it is convenient for shipping.

A 1.5-inch segment of roughly 200 hair strands (equivalent to a #2 pencil's width) closest to the scalp yields 100mg of hair, which is the optimal quantity for screening and confirmation. For tests such as EtG, add-ons, or those exceeding 10 panels, a sample of 150mg is advised. Utilizing a jeweler’s scale to measure the specimen is recommended. Should scalp hair be inaccessible, a comparable amount of body hair may be utilized. "Head hair" specifically denotes scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test comprises four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the initial integration of a sample into the laboratory system. This step involves ensuring the sample was sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.

Screening provides a preliminary assessment for drugs of abuse. While it is a cost-efficient method to dismiss drug use in most samples, a positive result in Screening must be corroborated to be legally valid. Presumptive positives in Screening necessitate additional confirmation.

Upon receiving a presumptive positive result from Screening, additional hair is extracted from the original specimen and readied for Extraction. This phase entails isolating drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), which accounts for the complexity of hair drug testing.

Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation if needed. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for a duration of up to 90 days, whereas urine tests have a briefer detection period.
• Challenging to manipulate: It is extremely difficult to circumvent a hair drug test, thus enhancing result reliability.
• Historical trend data: It can establish a drug use pattern over time, beyond just recent use.

Limitations:

• Incapable of capturing recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests typically incur higher costs than other drug testing techniques.
• Result variability: Elements like hair color and individual hair growth variations can influence drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
