Accredited Drug Testing offers comprehensive hair follicle drug screening in King of Prussia, Pennsylvania. If you're needing a drug or alcohol test with hair samples, our centers specialize in this method, with facilities in cities all over the country. Mostly, you'll require at least 1.5 to 2 inches of hair from your head or other body parts. Hair tests cover drugs, alcohol/ETG, and other tailored options.
Lately, hair follicle drug testing has become a more popular approach in conducting drug tests. Employers, courts, and Substance Abuse experts commonly prefer hair drug tests over standard urine tests. This method is vital for employers with strict no-drug policies, judicial purposes, and probation monitoring. Hair follicle testing provides a superior detection period, usually up to 90 days, is collected under observation, and is very hard to falsify. However, for drugs used within the last 5 days, urine tests remain more precise.

Hair testing is recognized as an effective method for identifying alcohol and drug usage. Hair retains biomarkers within the fibers of the growing hair shaft, providing an extended history of substance use. Hair taken near the scalp can reveal substance use for up to approximately three months. It is easy to collect, relatively hard to tamper with, and simple to transport.
A 1.5-inch section of around 200 hair strands (similar in thickness to a #2 pencil) near the scalp supplies 100mg of hair, which is optimal for screening and confirmation. For tests like EtG add-ons or those exceeding 10 panels, 150mg of the sample is preferable. Using a jeweler’s scale is advisable to weigh the specimen. If scalp hair isn't an option, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (such as facial, axillary, etc.).
Process Overview
The key stages in processing a drug test outcome in the lab include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is prepared for the lab's system. This process confirms the sample's proper sealing and shipment, issues a unique LAN (Laboratory Accessioning Number), and completes any missing data entry not supplied by an automated chain of custody system.
Screening entails an initial assessment for substances of abuse. While Screening efficiently rules out drug use in many cases, any positive screen requires Confirmation to be court-admissible. Samples testing presumptively positive in Screening undergo a secondary Confirmation.
If Screening yields a presumptively positive result, an additional hair portion is extracted from the initial sample and readied for the Extraction process. Here, drug extraction from hair happens at lower concentrations than other methods (such as urine or oral fluid), making hair drug tests among the most challenging to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS are used for confirming any positive results from Screening. Before Confirmation, all presumptive positive samples undergo a necessary washing. The lab processes from Accessioning to Confirmation are evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Although often called "hair follicle tests", the analysis is performed on the hair strand itself, not on the follicle beneath the scalp
