Accredited Drug Testing offers thorough hair follicle drug assessments in Clearfield, Pennsylvania. Our expertise lies in both hair and alcohol testing, and our facilities spread across various cities in the country are equipped to conduct these tests. Hair from the crown or other body parts ranging between 1.5 to 2 inches is typically required. These tests can detect drugs, alcohol/ETG, or other specialized options.
The preference for hair follicle testing for detecting drugs has been growing. Employers, legal authorities, and substance counselors often request hair tests over urine ones. Companies enforcing strict drug policies, judicial systems, and probation officers are primary users. Hair tests provide an extended substance detection window of around 90 days, and the collection is closely supervised, ensuring the results are hard to manipulate. Nevertheless, urine tests remain preferred for analyzing drug use within a recent five-day time frame.

Hair analysis has emerged as an effective method for detecting drug and alcohol usage. Hair captures a prolonged record of alcohol and other drugs by embedding biomarkers in the fibers of the growing strand. When gathered near the scalp, hair can offer up to roughly a 3-month detection timeframe for alcohol and other substances. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of approximately 200 strands of hair (comparable to a #2 pencil in size) nearest to the scalp will yield 100mg of hair, the optimal sample amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen weighing 150mg is advisable. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is inaccessible, an equivalent amount of body hair is a feasible alternative. Head hair refers solely to scalp hair, while body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The key stages in the laboratory processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial integration of a sample into the lab's framework. This step entails confirming the sample was appropriately sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody system.
Screening constitutes an initial rapid assessment for abusive drugs. Though Screening serves as an economical method to exclude drug usage in most samples, a positive result necessitates confirmation to be valid in judicial contexts. Samples with presumptive positives warrant follow-up confirmation.
Should a sample show presumptive positivity at the Screening phase, additional hair is extracted from the original sample to undergo Extraction. During this stage, drugs are removed from hair at a considerably lower concentration relative to alternative methods (such as urine or oral fluid), underscoring why hair drug analysis is uniquely challenging.
Confirmation of a positive screening outcome is executed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptively positive samples undergo cleansing prior to confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation is oversaw under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
