Hair Follicle Drug Testing - Lawrence, IN

What it is, How it works

Hair analysis is regarded as a robust method for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and other substances by preserving biomarkers within the strands as they grow. A sample taken near the scalp can offer an approximately 90-day detection span for alcohol and other substances. Hair is straightforward to gather, moderately challenging to tamper with, and easily transportable.

A sample measuring 1.5 inches, comprising about 200 hair strands (approximating the thickness of a #2 pencil), taken nearest to the scalp will yield 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or panels beyond 10, 150mg of the sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent portion of body hair may be utilized. When discussing head hair, it specifically means scalp hair solely. Body hair denotes all other hair varieties (facial, axillary, etc.).

Process Outline

The laboratory evaluation of a drug test result encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a lab's framework. This phase includes ensuring the sample is sealed and dispatched correctly, designating a unique LAN (Laboratory Accessioning Number), and completing any further data documentation absent from an electronic chain of custody system.

Screening comprises an initial rapid assessment for substance usage. Although Screening offers an economical method to eliminate drug consumption in most samples, any positive screening requires confirmation for judicial validity. Samples showing preliminary positive results in Screening demand secondary verification.

Should a sample yield a preliminary positive in the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. During this phase, substances are isolated from the hair at much reduced concentrations compared to other procedures (e.g., urine or oral fluid), underscoring the complexity of hair drug screening as a methodology.

Validation of any positive Screening outcome is achieved using GC/MS, GC/MS/MS or LC/MS/MS techniques. Before confirmation, presumptive positive samples undergo washing as necessary. The entire laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Benefits of hair drug analysis:

• Extended detection period: Hair drug assessments can uncover drug use extending to 90 days, unlike urine tests that have a more limited detection timeframe.
• Challenging to counterfeit: Compromising a hair drug analysis is highly complicated, thus enhancing result accuracy.
• Offers historical insight: It provides a record of substance use patterns over time, rather than only recent consumption.

Constraints:

• Unable to detect recent consumption: Detection of drugs in hair requires approximately 5-7 days.
• Expense: Hair drug assessments tend to be pricier than other drug examination techniques.
• Result variability: Influences such as hair color and personal differences in hair growth might alter the concentration of drug metabolites in the hair.

Note: Despite being colloquially labeled "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
