Hair Follicle Drug Testing - Timbercreek Canyon, TX

What it is, How it works

Hair testing has emerged as a crucial mechanism for identifying drug and alcohol use. Hair can chronicle a comprehensive history of substance intake by capturing biomarkers within the strands as they grow. When cut near the scalp, hair can provide up to roughly a three-month span for detecting both alcohol and drugs. Hair's collection is straightforward, less susceptible to tampering, and transportation is uncomplicated.

A segment of hair measuring 1.5 inches, comprising about 200 individual strands (about the thickness of a #2 pencil), when cut closest to the scalp, will yield 100mg of hair, which is optimal for analysis and confirmation. For EtG add-ons and/or tests beyond 10 panels, a 150mg sample is advised. It's advisable to use a jeweler's scale to weigh the sample. In the absence of scalp hair, an equivalent amount of body hair can be gathered. In our context, head hair pertains strictly to scalp hair. Body hair encompasses all hair varieties outside of the scalp (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test encompasses four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the preliminary handling of a sample into the laboratory’s system. It involves ensuring the sample's proper sealing and transportation, generating a unique LAN (Laboratory Accessioning Number), and carrying out any extra data entries not covered by an electronic chain of custody framework.

Screening entails conducting an initial rapid assessment for drugs of abuse. Screening is an economical means to exclude drug consumption for most samples, but any favorable screening results must undergo confirmation to be valid in judicial settings. Samples that show potential positive results in Screening necessitate a subsequent confirmation.

Upon showing presumptive positivity in the Screening phase, additional hair is extracted from the initial batch and readied for Extraction. This process involves extracting drugs from hair, with concentrations lower than seen in other testing types (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening as a method.

Confirmation for any positively screened sample is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples undergo washing prior to confirmation as deemed necessary. The entire laboratory procedure, from Accessioning through Confirmation, is subject to scrutiny under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests have the capacity to identify drug consumption for up to 90 days, contrasting with urine tests which have a shorter detection span.
• Hard to manipulate: Hair drug tests are difficult to falsify, resulting in more reliable outcomes.
• Yields historical insights: This kind of testing can reveal patterns of drug use across time, beyond mere recent consumption.

Limitations:

• Cannot detect recent consumption: There is a delay of approximately 5-7 days before drugs become traceable in hair.
• Expense: Hair drug tests tend to be costlier than alternative drug testing techniques.
• Variability in results: Characteristics like hair color and individual hair growth differences can impact drug metabolite concentrations in the hair.

Note: Despite being termed as "hair follicle tests", the analysis is conducted on the hair strand rather than on the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The reliability of hair follicle testing over traditional urine tests is evident in Timbercreek Canyon, TX. Hair tests offer an extended detection period and are harder to manipulate, ensuring higher accuracy in test results compared to urine tests.
