Hair Follicle Drug Testing - Ivanhoe North, TX

What it is, How it works

Hair analysis is regarded as a highly effective measure for detecting drug and alcohol consumption. Hair strands hold a historical record of alcohol and drug usage by embedding biomarkers within their fibers as they grow. When obtained near the scalp, hair can offer a detection timeframe of up to roughly three months for both alcohol and other substances. Collecting hair is straightforward, adulteration is moderately challenging, and transport is uncomplicated.

A hair sample measuring 1.5 inches, comprised of approximately 200 strands (about the circumference of a #2 pencil), closest to the scalp yields 100mg, which is optimal for screening and confirming. For EtG, supplementary substances, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest utilizing a jeweler’s scale for specimen weighing. If scalp hair is absent, a comparable quantity of body hair can be used. References to head hair pertain solely to scalp hair, while body hair refers to all other types (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into a laboratory’s system, including verification of proper sealing and shipment, allocation of a random LAN (Laboratory Accessioning Number), and completion of any additional data entry not provided by an electronic chain of custody system.

Screening is a preliminary rapid assessment for drug misuse. Although cost-effective for ruling out drug use in most samples, a positive screening must be further validated for court acceptance. Samples that test presumptively positive during Screening require subsequent confirmation.

Should a sample be presumptively positive during Screening, additional hair is taken from the initial specimen and prepped for Extraction. During this phase, drugs are isolated from the hair at considerably lower concentrations than with other methods (e.g., urine or oral fluid), rendering hair drug analysis as the most challenging methodology.

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

Advantages of hair drug testing:

• Prolonged detection period: Hair tests can identify drug use for as long as 90 days, in contrast to urine tests with a shorter detection span.
• Challenging to deceive: It is exceedingly difficult to manipulate a hair drug test, providing more precise results.
• Offers historical insight: It delivers a pattern of drug use over time, not merely recent occurrences.

Limitations:

• Incapable of detecting recent use: A period of approximately 5-7 days is required for drugs to be identified in hair.
• Expense: Generally, hair drug tests incur higher costs compared to other methods.
• Result variability: Factors such as hair color and individual hair growth differences can influence drug metabolite concentration within hair.

Note: Although often termed as "hair follicle tests", the test itself evaluates the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Ivanhoe North, TX presents several advantages over traditional urine tests. While urine tests are common, hair testing boasts superior detection accuracy and enhanced reliability. The longer detection window allows for a detailed overview of a person's drug history.

Extended Detection Window

Employers in Ivanhoe North, TX appreciate the extended detection window offered by hair follicle tests. Unlike short-period urine tests, hair tests can reveal drug use up to 90 days prior, offering a comprehensive understanding of an individual's behavioral trends. This extended timeframe is invaluable for assessing substance use history, supporting informed hiring and employment decisions.

Tamper-Resistant Testing Method

In Ivanhoe North, TX, hair follicle testing stands out as a tamper-resistant method of detecting substance use. By utilizing strands of hair rather than more conventional samples, this technique minimizes the chance of fraudulent results. The method's design ensures sample integrity, delivering unquestionable results that stand up under scrutiny, providing confidence in the validity of the test outcomes.
