Hair Follicle Drug Testing - Mcnair, VA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their growing fibers, offering a detailed timeline for drug and alcohol usage. Collected near the scalp, hair can reflect usage over a period of about three months. The collection process is straightforward, challenging to tamper with, and ensures seamless shipping.

An ideal sample involves 1.5 inches of approximately 200 hair strands (the thickness of a #2 pencil), yielding 100mg for thorough examination and verification. When testing for EtG, additional factors, or beyond 10 panels, it is advisable to collect 150mg. It's best to measure the specimen using a jeweler’s scale. If scalp hair isn’t accessible, a comparable quantity of body hair is suitable. 'Head hair' strictly refers to scalp hair, while 'body hair' encompasses all other types like facial and axillary hair.

Process Overview

The key stages in processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.

In the Accessioning stage, the sample undergoes initial processing into the lab’s system. This step ensures the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and finalizes any missing data not processed electronically.

Screening offers a quick scan for drugs of abuse. Though a cost-effective approach for clearing most samples of drug use, a positive result requires confirmation to be court admissible. Any samples identified as potentially positive during Screening necessitate a secondary verification.

For samples with a presumptive positive in the Screening phase, additional hair is extracted from the original specimen for further Processing. In this phase, drugs are separated from hair at a more diluted level compared to other techniques (such as urine or saliva), highlighting the complexity of hair drug testing.

Confirmation for any positive screening output is executed through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples receive a wash before confirmation if necessary. This comprehensive process, spanning from Accessioning to Confirmation, is thoroughly reviewed to meet both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection period: Hair drug assessments can trace drug use up to 90 days, as opposed to urine tests that offer a shorter timeline.
• Difficult to manipulate: Hair drug tests are challenging to falsify, ensuring higher accuracy in results.
• Offers historical insights: It traces a drug use pattern over time instead of just recent consumption.

Limitations:

• Inability to detect recent consumption: Detection in hair takes roughly 5-7 days after use.
• Expense: Hair drug assessments often come at a higher cost compared to other methods.
• Variability in outcomes: Elements such as hair color and individual hair growth differences influence the concentration of drug residues in hair.

Note: Commonly known as "hair follicle tests", the actual testing is conducted on the hair strand itself and not the follicle beneath the scalp
