Accredited Drug Testing offers thorough hair follicle drug assessments in Chesterfield, South Carolina. Seeking a hair-based drug or alcohol evaluation? Our expertise in hair testing includes nationwide facilities capable of conducting these tests. Generally, 1.5 to 2 inches of hair on your head or body is necessary for analysis, covering drugs, alcohol/ETG, or tailored testing options.
Recently, drug testing methods have increasingly relied on hair follicle tests. Businesses, judicial systems, and Substance Abuse experts now often prefer hair testing over typical urine tests. Hair tests, valued by those enforcing zero drug tolerance, probationary checks, or court directives, spotlight a broader detection window—often up to 90 days—performed under scrutiny and nearly impervious to manipulation. Nonetheless, for recent drug use within 5 days, urinalysis remains the definitive choice.

Hair analysis is now acknowledged as an effective means for identifying drug and alcohol involvement. It provides an extended-history record of substance intake by encasing biomarkers within the hair strand's evolving fibers. Hair, when clipped near the scalp, can represent a detection window of up to 3 months for alcohol and other substances. Collection is straightforward, tampering is challenging, and it ships conveniently.
To acquire an optimal sample, a 1.5-inch portion consisting of about 200 strands (equal in thickness to a #2 pencil) nearest the scalp is needed, equating to 100mg—the perfect amount for both screening and validation. For EtG, extra checks, or tests exceeding 10 panels, 150mg of the sample is advised. Use a jeweler's scale for accurate measurement. Should scalp hair be unavailable, a corresponding quantity of body hair can be utilized. Here, head hair exclusively signifies scalp hair, while body hair includes all other varieties (facial, auxiliary, etc.).
Process Overview
The laboratory procedure for a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial sample logging into a laboratory’s framework. This stage ensures the sample's seal and correct shipping, assigns a random LAN (Laboratory Accessioning Number), and finalizes any missing data not captured by an electronic chain of custody.
Screening performs an initial cursory inspection for illicit substances. Though cost-efficient for ruling out drug presence in numerous samples, positive screens require confirmation before legal admissibility. Presumptively positive samples necessitate additional verification.
Should a sample be ostensibly positive in Screening, extra hair from the original sample is prepared for Extraction. This involves obtaining drugs from hair at much lower concentrations than other techniques (e.g., urine or oral fluid) and is why hair drug testing is notably complex.
Confirmation of any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are appropriately cleaned before confirmation. The complete laboratory workflow from Accessioning to Confirmation is assessed per the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 norms.
