Hair Follicle Drug Testing - Mcnary, TX

What it is, How it works

Hair testing has gained prominence as a valuable method for identifying alcohol and drug consumption. Hair traps biomarkers within the fibers of the growing strand, providing an extensive history of substance use. When collected near the scalp, hair offers a potential detection period of up to three months for both alcohol and drugs. Hair is easy to collect, challenging to tamper with, and convenient to ship.

A 1.5-inch sample consisting of roughly 200 hair strands (approximately the size of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal sample for both screening and verification. For EtG, additional tests, or tests above 10 panels, 150mg of the hair is advisable. It is recommended to use a jeweler’s scale for specimen measurement. If scalp hair is not available, a similar amount of body hair can be gathered. Head hair specifically refers to scalp hair, while body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The laboratory process for drug test results consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning describes the primary processing of a sample into the laboratory system. This step includes confirming proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening performs an initial, swift examination for drugs of abuse. While cost-effective for eliminating drug usage in most samples, a positive screen result requires confirmation to be valid in court. Samples with a presumptive positive in Screening necessitate a secondary confirmation.

If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. Drugs are then extracted from the hair at significantly lower concentrations compared to other tests (e.g., urine or oral fluid), which contributes to the complexity of performing hair drug screenings.

Confirmation of positive screening results occurs through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if necessary. The entire process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, contrasting with urine tests which have shorter detection periods.
• Difficulty of manipulation: Cheating a hair drug test is highly challenging, ensuring more accurate results.
• Reveals usage patterns: It provides insight into habitual drug usage over time, rather than solely recent usage.

Limitations:

• Inability to detect recent use: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests tend to be more costly compared to other testing methods.
• Result variability: Factors such as hair color and individual hair growth rates can influence the concentration of drug metabolites in hair.

Note: Although commonly called "hair follicle tests", the test actually analyzes the hair strand, not the follicle located beneath the scalp.
