Hair Follicle Drug Testing - San Angelo, TX

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol use. Hair offers a comprehensive timeline of drug and alcohol intake by encapsulating biomarkers within the fibers of the hair as it grows. When gathered close to the scalp, hair can present a detection period of up to around 3 months for both alcohol and drugs. Hair is straightforward to collect, less prone to tampering, and convenient to transport.

A 1.5-inch section of roughly 200 strands of hair (about the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is perfect for analysis and validation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. It is suggested to weigh the sample with a jeweler's scale. If scalp hair isn't accessible, a comparable quantity of body hair can be used. References to head hair specifically mean scalp hair. Body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, initial handling of a sample into a lab's system takes place. This process includes confirming the sample's proper sealing and shipment, assigning a random Laboratory Accessioning Number (LAN), and completing any remaining data entry not covered by an electronic chain of custody system.

Screening entails a preliminary quick analysis for substances of abuse. While Screening is an economical method to exclude drug use in most samples, a positive screen requires confirmation to be legal in court. Samples that test presumptively positive in Screening necessitate further confirmation.

Should a sample test presumptively positive during Screening, additional hair is taken from the initial sample and readied for Extraction. At this stage, drugs are extracted from hair at a significantly lower concentration than in other techniques (e.g., urine or oral fluid), highlighting why hair drug screening is the most challenging methodology to execute.

Confirmation of any positive screening results is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized in accordance with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a more limited detection timeframe.
• Hard to compromise: It is highly challenging to tamper with a hair drug test, thus rendering the results more reliable.
• Conveys historical use: It reveals a pattern of drug use over time, not merely recent consumption.

Limitations:

• Inability to detect recent usage: It takes about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests are typically more costly than alternative drug testing techniques.
• Result variability: Elements like hair color and individual growth differences can influence the level of drug metabolites in the hair.

Note: Although often named "hair follicle tests", the analysis is conducted on the hair strand and not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

For residents and businesses in San Angelo, TX, hair follicle testing offers clear advantages over urine tests. The primary benefit is a longer detection window, up to 90 days, compared to the short detection period of urine tests. This provides an extended look at an individual's drug history.
Additionally, hair tests provide superior detection accuracy and reliability, making them an excellent choice for industries with strict drug-free policies that require uncompromising drug testing.

Extended Detection Window
