In Calvert, Texas, Accredited Drug Testing offers comprehensive hair follicle drug assessments. If you're in need of a hair-based drug or alcohol examination, our expertise in hair testing grants us centers across all American cities capable of conducting these assessments. Generally, 1.5 to 2 inches of hair from the head crown, or possibly other body parts, is needed. We analyze hair for drugs, alcohol/ETG, or any custom hair test requisites.
Recently, the prominence of hair follicle drug tests has risen in drug testing approaches. More and more employers, judicial systems, and Substance Abuse specialists opt for hair drug tests over typical urine analyses. Employers with rigorous no-drug policies, courts, and those on probation prioritize these tests. A hair follicle drug test's key advantage is its vast detection span for drug use, covering up to 90 days, via an observed collection process, minimizing cheating possibilities. Yet, the urine test remains supreme for drug detection within the preceding 5 days.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Recognized as a robust method for identifying drug and alcohol consumption, hair testing uses the embedded biomarkers within hair strands to offer an extended overview of substance use. By collecting hair near the scalp, a timeframe of up to about three months for detecting alcohol and drugs is achievable. The process of collecting hair is straightforward, not easily tampered with, and simple to transport.
An ideal collection involves a 1.5-inch segment of roughly 200 hair strands, akin to the thickness of a #2 pencil, which provides about 100mg, suitable for both screening and confirming presence. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advisable. It is suggested to measure the sample using a jeweler's scale. In the absence of scalp hair, a comparable quantity of body hair can be utilized. The term head hair relates exclusively to scalp hair, whereas body hair includes all other types (e.g., facial, axillary).
Process Overview
Key stages in processing a hair drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into a laboratory system initially. This phase ensures the sample's proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and fills in any additional information missing from the electronic chain of custody.
Screening consists of a preliminary examination for substances of abuse. While this method is cost-efficient for ruling out drugs in most samples, any positive results must undergo confirmation to be legally valid. Thus, samples with a presumptive positive result in Screening necessitate secondary validation.
During the Extraction process, additional hair is taken from the sample for further use if initial Screening suggests a positive. Drugs extracted from hair are at significantly lower concentrations compared to other methods (e.g., urine or saliva), making hair drug testing a more challenging approach.
Positive Screening results are confirmed through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing presumptive positives are cleansed before confirmation if needed. Each stage, from Accessioning to Confirmation, is audited following standards set by the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025.
