Accredited Drug Testing provides thorough hair follicle drug tests in San Isidro, Texas. If you're in need of a hair or alcohol test, Accredited Drug Testing excels in hair testing, with facilities available nationwide to conduct such tests. Hair length should be around 1.5 to 2 inches from the scalp or body, usable in many scenarios. These tests can verify drugs, alcohol/ETG, along with other customizable hair testing services.

In the past years, hair follicle tests have become an increasingly popular method for drug detection. A growing number of employers, judicial bodies, and Substance Abuse specialists favor these tests over traditional urine ones. Hair follicle tests are implemented by zero-tolerance employers, judicial systems, and for those on probation. Their advantage lies in a substantially longer detection span, generally up to 90 days, conducted under observation, making it almost foolproof. Nevertheless, for detecting very recent drug use, within 5 days, urine tests remain the most precise.

What it is, How it works

Hair assessments have emerged as a significant resource for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other drugs by encapsulating biomarkers within the strands of the growing hair. When sourced close to the scalp, hair can offer up to about a 3-month timeframe for detecting alcohol and other substances. Gathering hair is straightforward, relatively hard to tamper with, and simple to send.

A 1.5-inch segment of roughly 200 hair strands (approximately the girth of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal amount for analysis and verification. For EtG augmentations and/or assessments surpassing 10 panels, 150mg of the sample is suggested. Using a jeweler’s scale to measure the specimen is advisable. Should scalp hair be inaccessible, a comparable quantity of body hair can be secured. In mentioning head hair, we specifically mean scalp hair. Body hair signifies all other hair forms (facial, axillary, etc.).

Process Overview

The laboratory progression of processing a drug test outcome comprises four chief steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's preliminary processing session into a lab's system. This process incorporates confirming the sample's seal and proper dispatch, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not supplied by an electronic chain of custody framework.

Screening represents an initial brief assessment for substances of abuse. Though Screening is a resourceful means to dismiss drug usage for the majority of samples, a positive result requires confirmation to be permissible in court. Any samples considered presumptively positive during Screening require an additional confirmation step.

If a sample is deemed presumptively positive in the Screening phase, more hair is extracted from the primary specimen and prepared for Extraction. In this phase, drugs are drawn from hair at considerably lesser concentrations than other methods (ex. urine or oral liquid), explaining why hair drug screening is the most challenging method to execute.

To validate any positive screening outcome, GC/MS, GC/MS/MS, or LC/MS/MS is utilized. All samples labeled presumptive positive undergo washing before confirmation as necessary. The entire laboratory protocol from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

  • Prolonged detection frame: Hair drug testing can trace drug use for up to 90 days, unlike urine tests which offer a shorter frame.
  • Cheating difficulty: Cheating a hair drug test is very challenging, rendering the results more precise.
  • Deliver historical insights: It provides a pattern of drug consumption over a defined timeline, beyond just recent usage.

Limitations:

  • Recent usage undetectable: Roughly 5-7 days are needed for drugs to become detectable in hair.
  • Expense: Hair drug assessments typically incur higher costs compared to other testing methodologies.
  • Variance in findings: Factors like hair color and individual disparities in hair growth can impact drug metabolite levels in the hair.

Note: Although frequently termed "hair follicle tests", the evaluation itself examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing surpass urine testing in San Isidro? Hair tests deliver superior detection accuracy over traditional urine tests. Reliability is a major advantage, providing peace of mind to employers and decision-makers. The hair test method is not only thorough but also difficult to cheat, offering better scrutiny.

Unlike urine tests, hair testing captures a broader timeframe, ensuring no recent usage escapes detection. This enhanced capability makes it the go-to solution over simpler urine analysis, especially for companies keen on maintaining a clean standard.

Extended Detection Window

Hair follicle testing in San Isidro extends the drug detection window significantly, revealing substance use for up to 90 days. This provides a more comprehensive view of an individual’s history, which is beneficial for employers seeking long-term patterns rather than short-term slips.

The prolonged detection timeline means that an applicant or employee cannot conceal their past substance use as easily. This contributes to informed decision-making based on consistent behavior rather than potentially misleading short-term results.

Tamper-Resistant Testing Method

In San Isidro, hair follicle tests boast a tamper-resistant design, considerably curtailing sample adulteration. This provides reliable, unquestionable results, fostering trust in the testing process among employers and authorities alike.

Because hair samples are collected through direct observation, the opportunity for manipulation is minimal. This integrity in collection and analysis confirms the authenticity of the findings, significantly enhancing credibility and reducing doubts about the results.
