Accredited Drug Testing offers full-service hair follicle drug screenings in SeaTac, Washington. If a hair-based drug or alcohol screening is required, our specialty in hair testing is complemented by a network of centers nationwide equipped to perform these tests. Typically, 1.5 to 2 inches of scalp or body hair is necessary, and tests can detect drugs, alcohol/ETG, or be tailored for specific requirements.
In recent years, the shift toward hair follicle drug testing has gained momentum. Employers, judicial systems, and substance abuse experts are increasingly opting for hair tests over urine tests. Their advantage lies in up to 90 days of drug use detection, collected under observation, offering a tamper-proof process. Nevertheless, for detecting recent drug use within five days, urine tests remain more precise.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. The hair traps indicators within the fibers of the strand, offering a comprehensive timeline of substance usage. When taken near the scalp, hair can reveal drug or alcohol use over a span of around three months. Collection is straightforward, tampering is not easy, and transportation is hassle-free.
Collecting a 1.5-inch portion containing about 200 hairs (similar to a #2 pencil width) near the scalp yields 100mg, ideal for both screening and verification. For EtG, additional tests, or beyond 10 panels, a 150mg sample is suggested. It’s advisable to measure the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair may be used. Here, head hair means scalp hair only, whereas body hair includes all other forms (beard, armpit, etc.).
Process Overview
The testing process is comprised of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about integrating the sample into the laboratory’s system, ensuring it was sealed and transported correctly, assigning a LAN (Laboratory Accessioning Number), and finalizing any additional data entries that an electronic chain of custody system may have missed.
Screening consists of a preliminary assessment for drug traces. It is an economical method to exclude drug use for most samples, though a positive result in this phase must be validated for legal purposes. Samples that are preliminarily positive necessitate a confirmatory test.
Presumptively positive samples then progress to the Extraction phase where additional hair is prepared. Here, drugs are retrieved from the hair at lower concentrations compared to other methods (like urine or saliva), making hair analysis a challenging procedure.
Verification of any preliminary positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, presumptive positives undergo necessary washing. The total laboratory operation, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
