Accredited Drug Testing offers comprehensive hair follicle drug testing services in Terral, Oklahoma. If you're in need of a hair-based drug or alcohol test, Accredited Drug Testing has expertise in hair testing and operates testing centers across every city Nationwide capable of conducting such tests. Generally, 1.5 to 2 inches of hair from the crown or body is sufficient. Hair analysis can screen for drugs, alcohol/ETG, and other specialized testing solutions.
Recently, drug testing methodologies have increasingly incorporated hair follicle drug tests. A growing number of employers, judicial systems, and Substance Abuse experts are opting for hair drug tests versus the conventional urine tests. Hair follicle drug tests are preferred by organizations enforcing strict no-drug-use policies, courts, and probation officers. The major advantage of hair follicle testing is its extended detection range for substance use, typically up to 90 days, it is collected under supervision, and it is highly resistant to tampering. Nevertheless, for detecting drug use within the recent five days, urine tests still remain the most precise.

Hair analysis is recognized as an effective means for detecting drug and alcohol use. Hair captures a long-term record of alcohol and drug consumption by embedding biomarkers within the strands of hair as it grows. Collected near the scalp, hair offers a detection window of up to around three months for alcohol and drugs. Hair samples are easy to gather, challenging to tamper with, and straightforward to transport.
A sample measuring 1.5 inches, containing roughly 200 strands (approximating the thickness of a #2 pencil), yields 100mg of hair—an amount ideal for screening and confirmation. For EtG, extended tests, and/or panels exceeding 10, 150mg of the specimen is advised. It is advisable to weigh the specimen using a jeweler's scale. If scalp hair cannot be sourced, an equivalent amount of body hair is acceptable. Notably, head hair references only scalp hair, whereas body hair encompasses all other forms (facial, axillary, etc.).
Process Overview
The primary stages involved in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a lab’s system. This process entails verifying that the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any other data entry not included via an electronic chain of custody system.
Screening serves as a preliminary assessment for detecting drugs of abuse. Although Screening offers a cost-efficient method to eliminate drug usage on most samples, a positive screen requires confirmation to hold up legally. Samples identified as presumptively positive in Screening necessitate secondary confirmation.
Should a sample yield a presumptively positive result during Screening, additional hair is extracted from the initial specimen for Extraction. This stage involves extracting drugs from hair in substantially lower concentrations than methods like urine or oral fluid, leading to the complexity of performing hair drug screening.
Confirmation of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive results undergo washing prior to confirmation if necessary. The full lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
