By providing extensive hair follicle drug tests in Knoxville, Tennessee, Accredited Drug Testing excels. If you're in need of a hair drug or alcohol analysis, we specialize in this field, with testing centers throughout all Nationwide cities available for this service. A minimum of 1.5 to 2 inches of hair from the crown or body serves as a requisite for testing. These tests can determine the presence of drugs, alcohol/ETG, and other distinct testing options.
In recent times, the hair follicle drug test has become a more common method of testing. Employers, judicial systems, and Substance Abuse professionals are often choosing hair testing instead of the conventional urine test. This approach is preferred by employers enforcing strict anti-drug policies, court systems, and probationary programs alike. The central advantage is its broader detection window, covering up to 90 days, collected under observation, and offering high resistance to tampering. However, for substances used within the last five days, urine tests remain the most accurate.

Hair analysis is increasingly recognized as an effective method for discovering substance and alcohol use. Hair captures a comprehensive timeline of alcohol and drugs by entrapping biomarkers within the fibers of its developing strand. When clipped near the scalp, hair offers a detection range lasting up to about 3 months for alcohol and drugs. Hair is straightforward to collect, fairly resistant to tampering, and simple to dispatch.
A 1.5-inch section consisting of roughly 200 hairs (approximately the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for screening and validation. For EtG extensions, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the specimen with a jeweler’s scale. If scalp hair is unavailable, a similar volume of body hair may be gathered. Referring to head hair indicates scalp hair exclusively. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The essential steps in laboratory processing of drug test outcomes encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary handling of a sample within a lab’s system. It involves checking that the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and concluding any additional data entry absent from electronic custody records.
Screening delivers a swift assessment for illicit substances. As an economical method to exclude substance usage on most samples, a positive screen mandates confirmation for judicial acceptability. Samples with presumptive screening positives must undergo secondary confirmation.
Should a sample be presumptively positive at the Screening phase, more hair is extracted from the original sample and readied for Extraction. Here, substances are withdrawn from hair at considerably lower concentrations versus other methods (e.g., urine or saliva), illustrating why hair drug assessment is highly complex.
A positive screening outcome is confirmed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive are cleaned prior to required confirmation. The entire lab procedure from Accessioning to Confirmation experiences scrutiny under CAP’s Hair category and ISO / IEC 17025 accreditation.
