Accredited Drug Testing provides comprehensive hair follicle drug testing services in Corryton, Tennessee. Whether you need a drug or alcohol test through hair analysis, we are experts in this field with testing locations in every city across the country that can conduct such tests. Generally, 1.5 to 2 inches of hair from your head or body is needed. Hair can be checked for drugs, alcohol/ETG, or other tailored testing options.
In the past few years, the preference for drug testing methods has shifted towards hair follicle testing more frequently. Employers, courts, and Substance Abuse experts are increasingly opting for hair drug tests over the common urine tests. Employers with strict no-drug-use rules, court systems, and those on probation often rely on hair drug tests. The biggest advantage of this method is its extended detection timeline for drug use, typically up to 90 days, with results collected through an observed process, making it nearly tamper-proof. However, for drug usage within the last five days, urine tests remain the most precise.

Hair analysis has emerged as an effective method for identifying alcohol and drug consumption. Hair captures a comprehensive timeline of substance use by embedding biomarkers within the strands as they grow. Collected near the scalp, hair can reveal usage history spanning roughly three months for substances like alcohol and other drugs. The process of hair collection is straightforward, manipulation is relatively challenging, and transport is easy.
A hair sample measuring 1.5 inches from about 200 strands (comparable to the diameter of a #2 pencil) nearest the scalp yields 100mg, which is the optimal amount for both screening and confirmation. For tests such as EtG, additional screenings, or panels exceeding 10, a 150mg specimen is advisable. We suggest using a jeweler’s scale to measure the specimen. Should scalp hair be unavailable, equivalent quantities of body hair may be utilized. Head hair refers exclusively to scalp hair. Body hair encompasses all other types such as facial or axillary hair.
Process Overview
The laboratory process for drug testing includes four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase where a sample is processed into the laboratory’s database. This phase ensures that the sample is correctly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and enters any additional data not available through an electronic chain of custody.
Screening performs a preliminary assessment for controlled substances. While Screening is a budget-friendly method for excluding drug use in most samples, any positive findings must be verified to be valid in legal scenarios. Samples with presumptive positives in Screening necessitate further confirmation.
When a sample is presumptively positive during the Screening phase, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are extracted from hair at a lower concentration than in alternative methods (e.g., urine or oral fluid), making hair drug testing a particularly complex process.
Confirmation for any positive screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed prior to confirmation as required. The comprehensive process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
