Hair Follicle Drug Testing - Kingstown, MD

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. It provides an extended timeline of substance intake by capturing biomarkers within the fibers of the hair as it grows. When hair is collected near the scalp, it offers a detection period for alcohol and drugs extending up to approximately 3 months. The collection process is straightforward, tampering is challenging, and transportation is convenient.

A 1.5-inch segment comprising roughly 200 hair strands (analogous to the thickness of a #2 pencil) from the area nearest to the scalp provides 100mg of hair, which is optimal for testing and verification. For EtG, additional panels, and/or tests exceeding 10 panels, a 150mg sample is advised. It is best to weigh the specimen using a jeweler’s scale. Should scalp hair be unavailable, a proportional amount of body hair can be used. References to head hair pertain solely to scalp hair. All other hair types (facial, axillary, etc.) are considered body hair.

Process Overview

The drug test result processing in the laboratory encompasses Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial integration of a sample into the lab system. This phase entails confirming that the specimen was properly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and executing any requisite data entry absent from an electronic chain of custody system.

Screening is a preliminary rapid assessment for drug abuse indicators. While it's a cost-effective strategy for excluding drug usage in most cases, a positive screen must undergo confirmation to be legally viable. Samples indicative of drug presence in Screening necessitate a secondary confirmation.

For samples flagged as presumptively positive during Screening, additional hair is drawn from the original sample and prepared for Extraction. In this process, drugs are isolated from hair at significantly lower concentrations than in other test forms (e.g., urine or saliva), underscoring the complexity of hair drug screening compared to other methodologies.

Verification of positive screening outcomes is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleaned before verification if necessary. The complete procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug assessments can detect usage for up to 90 days, unlike urine tests which have more limited detection timelines.
• Challenging to manipulate: Cheating a hair drug test is notably difficult, ensuring greater result accuracy.
• Offers historical insight: It illustrates a pattern of drug consumption over time, rather than just recent use.

Limitations:

• Unable to indicate recent use: Detection of drugs in hair takes approximately 5-7 days post-use.
• Expense: Generally, hair drug tests are pricier than alternative testing methods.
• Result variability: Characteristics like hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Commonly referred to as "hair follicle tests", the analysis actually focuses on the hair strand, not the follicle beneath the scalp
