Hair Follicle Drug Testing - Gulf, NC

What it is, How it works

Considered an effective means for detecting drug and alcohol consumption, hair testing offers a prolonged history of substance use by capturing biomarkers within the strands of hair as it grows. Collecting hair near the scalp yields a detection period of up to about 3 months for alcohol and other drugs. The collection of hair is straightforward, not easily tampered with, and convenient to transport.

A 1.5-inch section consisting of approximately 200 hair strands (roughly equivalent to the width of a #2 pencil) closest to the scalp provides 100mg of hair, which is the perfect sample size for both screening and confirmation. For those tests involving EtG, additional components, and/or those surpassing 10 panels, a specimen weighing 150mg is advisable. Usage of a jeweler’s scale for measuring the specimen is suggested. Should scalp hair not be an option, a comparable quantity of body hair can be used. The term head hair specifically refers to scalp hair, whereas body hair encompasses all other hair categories (such as facial, axillary, etc.).

Process Overview

Four primary steps characterize the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial integration into a lab's operational system—this phase ensures proper sealing and shipping of samples, assigns a random LAN (Laboratory Accessioning Number), and completes any supplemental data required aside from what an electronic chain of custody might offer.

Screening provides an initial assessment of sample for drugs of abuse. Although Screening serves as a cost-effective method to exclude drug consumption for most samples, samples yielding a positive result necessitate confirmation to hold legal validity. Presumptive positives from Screening prompt further confirmation.

For presumptive positives during Screening, additional hair is extracted from the original sample and readied for Extraction. This phase involves retrieving drugs from hair at much lower concentrations than other methods such as urine or oral fluid, positioning hair drug testing as a particularly complex method to conduct.

Positive Screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are pre-confirmation cleansed as appropriate. Every step from Accessioning to Confirmation is scrutinized in alignment with both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests trace drug use up to 90 days, unlike urine tests which offer a more limited detection timeframe.
• Challenging to manipulate: Hair drug tests are particularly resistant to deception, ensuring more reliable results.
• Historical usage data: They provide an overview of drug consumption over time rather than just recent activity.

Limitations:

• Lacks recent use detection: Drugs become traceable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Result variability: Elements such as hair color and unique individual hair growth affect the drug metabolites' concentration in hair samples.

Note: Often labeled as "hair follicle tests", the actual examination is conducted on the strand of hair rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
