Accredited Drug Testing offers extensive hair follicle drug testing services in Dauphin, Pennsylvania. If it's a hair drug or alcohol test you seek, our expertise in hair testing is unparalleled with centers available across all cities Nationwide to conduct such tests. Typically, 1.5 to 2 inches of hair from the crown or body suffices. Hair samples can be examined for drugs, alcohol/ETG, or tailored testing choices.
In the past years, hair follicle drug tests have gained popularity in drug testing processes. Employers, judicial systems, and Substance Abuse experts increasingly favor hair tests over the standard urine tests. Employers with zero-tolerance drugs policies, legal institutions, and probationary individuals depend on hair follicle tests due to their comprehensive 90-day detection capability, monitored collection procedure, and the near impossibility of tampering. That said, for detecting most recently used drugs, within five days, urine tests remain the gold standard.

Hair testing is recognized as a compelling method for unveiling drug and alcohol consumption. Hair captures a prolonged history of substances by absorbing biomarkers within the strands as they grow. Collecting hair near the scalp can reveal alcohol and drug use within a roughly three-month timeframe. Hair is easy to gather, challenging to tamper with, and convenient to dispatch.
A sample measuring 1.5 inches with 200 hair strands (approximately the thickness of a #2 pencil) from the scalp provides 100mg of hair, which is the optimal quantity for analysis and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler's scale for measurement. In the absence of scalp hair, a comparable amount of body hair can be submitted. When mentioning head hair, we refer specifically to scalp hair. The term body hair encompasses all other types (facial, underarm, etc.).
Process Overview
The procedure to process a drug test result in the lab encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the first step in integrating a sample into the laboratory’s systems. This phase includes confirming that the sample was appropriately sealed and delivered, assigning it a unique LAN (Laboratory Accessioning Number), and completing any other essential data input not covered by an electronic chain of custody.
Screening represents an initial assessment for substances of misuse. While it is a cost-efficient way to rule out drug presence in numerous samples, a positive result needs a confirmed test to be legally viable. Any samples that show presumptive positivity must undergo additional confirmation.
For samples with a presumptive positive result in Screening, additional hair is retrieved from the main sample and readied for Extraction. Here, substances are withdrawn from the hair at lower concentrations compared to other techniques (such as urine or oral fluid), underscoring why hair drug testing is one of the most complex methodologies to execute.
Confirming a positive Screening result takes place with GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive are cleansed before confirmation if required. The end-to-end lab procedure, from Accessioning through Confirmation, proceeds under the CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 standards.
