Hair Follicle Drug Testing - Martindale, TX

What it is, How it works

Hair examination has emerged as an effective method for identifying drug and alcohol consumption. It provides an extended retrospective of substance use by encasing biomarkers within the hair structure. When clipped near the scalp, this method can offer up to roughly a three-month detection timeframe for alcohol and drugs. The collection process is straightforward, challenging to tamper with, and facilitates easy transport.

A sample of 1.5 inches involving around 200 hair strands (comparable to the breadth of a #2 pencil) closest to the scalp yields 100mg, which is optimal for analysis and confirmation. For EtG variations, additional requirements, and/or more than 10 panels, 150mg of the specimen is advised. We propose weighing the sample on a jeweler's balance. Should scalp hair not be available, a corresponding volume of body hair may be utilized. When referencing head hair, this pertains exclusively to scalp hair. Body hair encompasses other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing for drug test results consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary integration of a sample into the laboratory framework. Tasks involve ensuring the sample was securely enclosed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data input absent from an electronic chain of custody system.

Screening carries out an initial swift assessment for drugs of abuse. While this is a cost-efficient approach to exclude drug usage in most cases, a positive screening demands confirmation to hold validity in legal settings. Samples showing presumptive positives in Screening necessitate additional affirmation.

At the Screening phase, if a sample indicates a presumptive positive, more hair is extracted from the initial collection and prepared for Extraction. Here, drugs are retrieved from hair at much lesser concentrations than with other methods (e.g., urine or saliva), establishing hair drug analysis as one of the most challenging methodologies to execute.

Confirmation for any positive screen is performed employing GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing as applicable before confirmation. The complete laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug assessments can identify drug usage for up to 90 days, unlike urine tests which offer a limited detection span.
• Hard to manipulate: It is notably difficult to falsify a hair drug test, which enhances the reliability of the outcomes.
• Delivers historical insights: It can outline a sequence of drug use over time, not merely recent episodes.

Limitations:

• Incapacity to detect recent consumption: It requires roughly 5-7 days for drugs to manifest in hair.
• Expense: Hair drug assessments are usually costlier than alternative testing techniques.
• Result fluctuations: Elements like hair shade and individual differences in hair growth can influence drug metabolite levels in the hair.

Note: Commonly referred to as "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing surpasses urine tests in effectiveness, especially in Martindale, TX. By providing superior detection capabilities, hair analysis offers a more comprehensive assessment of substance use. This method excels in identifying long-term drug use, which urine tests lack due to their shorter detection window.

Extended Detection Window

Hair follicle testing in Martindale, TX, offers an extended detection period, crucial for employers who require an in-depth substance use history. While traditional tests might miss substances taken outside their limited detection window, hair tests can reveal drug use up to 90 days prior. This long-term view allows employers to make informed decisions, offering a broader look into an individual's drug use history.

Tamper-Resistant Testing Method

In Martindale, TX, the hair follicle test method effectively reduces the risk of tampering, a common concern with other drug testing methods. The reliability of results is paramount, and hair tests offer unmatched security in this aspect. Unlike urine tests, which might be doctored or contaminated, hair analysis presents an almost impenetrable barrier to ensuring the authenticity of the specimen collected.
