Hair Follicle Drug Testing - Toxey, AL

What it is, How it works

Hair analysis is widely recognized as an effective means for identifying substance and alcohol consumption. By encapsulating biomarkers within the strands, hair offers an extended historical record of alcohol and drugs use. When collected from the scalp, it can yield a detection span that extends approximately three months for both alcohol and drugs. Hair sampling is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch section consisting of roughly 200 hair strands (akin to the size of a #2 pencil) taken closest to the scalp supplies 100mg of hair, which is perfect for both screening and subsequent validation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. A jeweler’s scale is recommended for weighing the specimen. If there’s a lack of scalp hair, a similar quantity of body hair can be harvested. The term head hair pertains solely to scalp hair, whereas body hair includes other types (such as facial or axillary hair).

Process Summary

There are four key phases involved in the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial integration of a specimen into a lab's system. It covers the verification of the sample’s proper sealing and shipment, assignment of a random LAN (Laboratory Accessioning Number), and completion of any remaining data input absent from an electronic chain of custody system.

Screening constitutes a preliminary rapid assessment for substances of abuse. While it offers a cost-effective approach to negate drug consumption in most specimens, a positive screen necessitates validation for court admissibility. Samples with presumptive positives warrant a secondary confirmation.

For any presumptive positives discovered in the Screening phase, additional hair is extracted from the original sample and made ready for Extraction. During this phase, substances are isolated from hair at markedly lower concentrations than other techniques (such as urine or oral fluids), making hair drug screening the most challenging method to execute.

Verification of any positive screening outcomes is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with positive presumptions are washed before confirmation if circumstances require it. The entirety of the laboratory procedures from Accessioning to Confirmation is overseen in compliance with the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 standards.

Benefits of hair drug analysis:

• Extended detection duration: Hair tests can trace drug consumption up to 90 days, unlike urine tests which offer a shorter detection timeframe.
• Challenge to deceive: It is exceedingly complex to defraud a hair drug test, hence the results are more precise.
• Supplies historical records: It can outline a pattern of drug consumption over a timeline, not solely recent ingestion.

Drawbacks:

• Incapable of identifying recent consumption: It requires about 5-7 days for substances to register in hair.
• Expense: Hair drug testing tends to be costlier than alternative testing methods.
• Result variability: Factors like hair color and personal hair growth variations can influence drug metabolite concentrations within hair.

Note: Although commonly called "hair follicle tests", the examination focuses on analyzing the hair strand rather than the follicle beneath the scalp.
