Accredited Drug Testing offers comprehensive hair follicle drug tests in Hickory Hill, Pennsylvania. Specializing in both hair drug and alcohol testing, we have Nationwide centers that conduct hair tests. Typically, at least 1.5 to 2 inches of hair from the crown or body is required. Hair tests can detect drugs, alcohol/ETG, and other specified options.
Over recent years, hair follicle testing has become a preferred drug test method. Many employers, courts, and Substance Abuse specialists now opt for hair tests over urine tests. These tests are useful for organizations enforcing zero-tolerance policies, courts, and those on probation. Notably, hair tests detect drug use over a 90-day period, are conducted under observation, and are hard to tamper with. However, for recent drug usage within 5 days, urine tests remain more precise.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair testing is widely recognized as an effective method for detecting drug and alcohol use. Hair offers a comprehensive timeline of alcohol and drugs by embedding biomarkers within the fibers of the growing strand. When taken near the scalp, hair can reveal drug and alcohol use over an approximate 3-month period. Hair collection is straightforward, fairly resistant to tampering, and simple to transport.
A sample consisting of a 1.5-inch length of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, add-ons, or tests involving more than 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale for weighing the sample. If scalp hair isn't available, an equivalent amount of body hair should be used. By "head hair," we mean scalp hair alone. "Body hair" refers to every other type (facial, axillary, etc.).
Process Overview
The laboratory processing for a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial sample integration into a laboratory’s system. This process checks whether the sample was appropriately sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and completes any extra data entry omitted by an electronic chain of custody system.
Screening conducts an initial rapid assessment for drugs of abuse. Screening provides a cost-effective method to dismiss drug use in most samples; however, for legal admissibility, a positive result requires confirmation. Any samples with a presumptive positive in Screening necessitate a subsequent confirmation.
Should a sample be presumptive positive at the Screening stage, additional hair is extracted from the original specimen and prepared for Extraction. In Extraction, drugs are retrieved from hair at much lower concentrations than in other methods (like urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of positive screening results is performed using GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing if needed. The overall lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
