Accredited Drug Testing provides comprehensive hair follicle testing services in King, North Carolina. For those in need of a hair drug or alcohol test, turn to Accredited Drug Testing, which focuses on hair analysis and has testing centers across the nation, ready to perform hair assessments. Typically, 1.5 to 2 inches of hair from the head or body is sufficient for testing. Hair assays can be customized to detect drugs, alcohol/ETG, or other specific needs.
In recent times, hair follicle testing has become a more prevalent choice in drug testing methods. Many workplaces, judicial systems, and substance abuse experts now opt for hair testing over conventional urine tests. Hair follicle tests are ideal for employers enforcing no-drug policies, courts, or those on probation. This method's key advantage is its prolonged detection ability, extending up to 90 days, collected under direct supervision, making it extremely difficult to tamper with. That said, for detecting recent drug use within the last five days, urine tests remain the most 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 increasingly recognized as an effective means of identifying drug and alcohol consumption. Hair captures a historical record of alcohol and drug intake by encasing biomarkers within the hair shaft's fibers. When hair is taken from the area closest to the scalp, it can reveal drug and alcohol use for roughly 90 days. Hair collection is straightforward, hard to falsify, and convenient to transport.
A hair sample taken near the scalp, measuring 1.5 inches and consisting of around 200 strands (about the thickness of a #2 pencil), will yield 100mg, which is the ideal sample size for both screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, a quantity of 150mg is advisable. Using a jeweler's scale for measuring the specimen weight is suggested. If scalp hair is unavailable, an equivalent amount of body hair can be taken. In mentioning head hair, we specifically mean scalp hair, whereas body hair includes all other types, such as facial and axillary hair.
Process Overview
The four key stages in the analysis of a drug test result by a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the lab's database. This phase ensures the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry not captured by the electronic chain of custody system.
Screening is a preliminary check for drug consumption. Though Screening is an economical method to exclude drug consumption in most samples, a positive screen must be authenticated to hold legal validity. Any samples indicating a presumptive positive during Screening need further confirmation.
If Screening suggests a positive result, additional hair is extracted from the original sample for further processing. In Extraction, drugs are isolated from hair at significantly lower concentrations compared to other procedures (like urine or oral fluids), highlighting the complexity of hair drug testing.
GC/MS, GC/MS/MS, or LC/MS/MS is utilized for the Confirmation of any positive screening outcomes. Presumptive positive samples are washed before confirmation when necessary. From Accessioning through Confirmation, the laboratory procedure is scrutinized under both CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation standards.
