Accredited Drug Testing offers comprehensive hair follicle drug testing services in Penryn, Pennsylvania. If you require a hair drug or alcohol analysis, our expertise in hair testing is unmatched, with facilities available across all major cities. Typically, a hair sample between 1.5 to 2 inches from the scalp or body is needed. Our hair tests can screen for drugs, alcohol/ETG, and other tailored options.
Recently, hair follicle drug tests have become increasingly common for drug screenings. Employers, judicial systems, and substance abuse counselors now often prefer these tests over urine testing. The appeal lies in their use by entities with strict no-drug policies and those overseeing probation. The central advantage is the extended detection window, generally lasting up to 90 days, making tampering nearly impractical. However, for identifying recent drug use within five days, urine tests remain preferable.

Hair analysis is recognized as a potent instrument for detecting the use of drugs and alcohol. Hair captures a historical record of alcohol and other substances by embedding biomarkers within its fibers during growth. When sampled near the scalp, hair offers a detection period of nearly three months for alcohol and additional drugs. The collection of hair samples is straightforward, challenging to tamper with, and convenient for shipping.
A sample of 1.5 inches, consisting of roughly 200 hair strands (similar in size to a #2 pencil) closest to the scalp, amounts to 100mg, the optimal quantity for both screening and confirmation processes. For EtG, supplementary tests, and/or panels exceeding 10, a sample of 150mg is advocated. Using a jeweler’s scale for weighing the sample is recommended. If head hair is not accessible, an equivalent amount of body hair may be used. Head hair specifically refers to scalp hair, while body hair encompasses other types such as facial and axillary hair.
Process Overview
There are four key stages in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial entry of a specimen into the laboratory system. This step involves checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and executing any extra data input not covered by an electronic chain of custody system.
Screening involves a preliminary examination for the presence of drugs. Though Screening is an economical way to eliminate drug use for most samples, samples testing positive require confirmation for court acceptance. Presumptively positive samples in Screening must undergo secondary confirmation.
When a sample is presumptively positive during the Screening phase, additional hair is taken from the original sample and processed for Extraction. In this phase, drugs are drawn from hair at concentrations much lower than other methods (e.g., urine or oral fluid), marking hair drug screening as the most challenging method to execute.
Confirming any positive result from screening is executed through GC/MS, GC/MS/MS or LC/MS/MS methods. All samples that are presumptively positive undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation is evaluated based on the CAP (College of American Pathologists) Hair standard and accredited to ISO / IEC 17025 norms.
