Accredited Drug Testing offers comprehensive hair follicle drug testing services in Collinsville, Virginia. If you're in need of hair drug or alcohol testing, we specialize in hair tests, with testing centers available across all cities nationwide. Ensure you have 1.5 to 2 inches of hair from your scalp or body, as most instances permit this. Hair testing can screen for drugs, alcohol/ETG, or customized options tailored to your needs.
Over recent years, hair follicle drug testing has grown more prevalent. Employers, courts, and Substance Abuse specialists often prefer hair drug tests over traditional urine tests. Employers with zero-tolerance drug policies, judicial systems, and those on probation opt for hair follicle testing. Its prime advantage is the extended detection period—typically, up to 90 days—obtained through an observed process, minimizing cheating. However, for detecting recent drug use within 5 days, urine tests still prove 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 recognized as an effective means for detecting drug and alcohol consumption. By capturing biomarkers within the fibers of hair strands, hair offers a long-term profile of drug and alcohol use. Sampling hair near the scalp can reveal drug and alcohol presence for up to approximately 90 days. The process of collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample size of 1.5 inches, comprising about 200 hair strands (comparable to the thickness of a #2 pencil) from the scalp, yields 100mg, the optimal amount for testing and verification. For EtG testing, additional analysis, and tests exceeding 10 panels, 150mg is ideal. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't available, an equal measurement of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (such as facial or axillary hair).
Process Overview
The laboratory processing for drug testing involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is processed into a laboratory's system. This step includes ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry that an electronic chain of custody system may not have provided.
Screening serves as an initial assessment for substances of abuse. While Screening efficiently rules out drug use for most samples, any positive results must be confirmed to be legally valid. Samples that return a presumptive positive result in Screening require further confirmation.
For samples that test presumptively positive during Screening, additional hair is taken from the original sample and readied for Extraction. Drugs are extracted from hair at notably lower concentrations compared to other methods like urine or saliva, making hair drug screening one of the more challenging methodologies.
Positive screening results are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples testing presumptively positive undergo washing before confirmation, if needed. Every step from Accessioning to Confirmation follows a review process in line with CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
