Accredited Drug Testing offers comprehensive hair follicle drug assessments in Knox, Pennsylvania. For those needing a drug or alcohol evaluation using hair samples, we specialize in such tests with facilities nationwide. Generally, 1.5 to 2 inches of crown hair or body hair is adequate. Hair analysis can screen for drugs, alcohol/ETG, or other tailored testing protocols.
Recently, hair follicle drug analysis has become a more popular method. Many businesses, judicial systems, and substance abuse specialists now prefer it over traditional urine tests. Hair follicle assessments cater to employers with zero-tolerance policies and individuals under probation. Its major advantage includes a detection span of up to 90 days, with secure collection making it hard to tamper with. However, for recent drug activity, urine tests remain the gold standard within a 5-day period.

Hair testing is regarded as a robust method for detecting drug and alcohol consumption. It provides an extensive record of substance use by embedding biomarkers in the strands as they grow. When sourced near the scalp, hair can offer approximately a 3-month retrospective window for detecting drugs and alcohol. This method is straightforward to perform, relatively resistant to tampering, and convenient for transport.
A hair specimen measuring 1.5 inches, consisting of around 200 strands (similar to the width of a #2 pencil), yields about 100mg, which is optimal for both screening and confirmation tests. For comprehensive tests, such as EtG, additional panels over 10 require 150mg. It's advisable to use a jeweler’s scale for precision. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. 'Head hair' specifically refers to scalp hair, while 'body hair' covers all other types (e.g., facial, axillary).
Process Overview
The laboratory procedures for processing drug test results encompass four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the beginning of sample processing within a laboratory system, ensuring the sample is properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening offers a preliminary assessment for substances of abuse. Although Screening is a cost-efficient means for negating drug use in most samples, positive results require further Confirmation to be valid for legal purposes. Any samples flagged during Screening need a subsequent confirmation step.
Should the Screening phase indicate a presumptive positive, additional hair from the original sample is used for Extraction. This phase involves extracting drugs from the hair at concentrations lower than those in other techniques like urine or oral fluid testing, making hair drug screening particularly challenging.
Confirmation of positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, all presumptive positive samples are washed if necessary. This entire laboratory process, from Accessioning to Confirmation, undergoes rigorous review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
