Accredited Drug Testing offers comprehensive hair follicle drug testing in Lawrence, Indiana. When a hair drug or alcohol test is needed, Accredited Drug Testing is the go-to for hair tests, available in all cities nationwide. Typically, 1.5 to 2 inches of head or body hair is required. Hair tests can screen for drugs, alcohol/ETG, or other tailored options.
Hair follicle drug tests have become more prevalent recently. Employers, courts, and substance abuse professionals often favor this method over traditional urine tests due to its extended detection period of up to 90 days, observed and hard to cheat. However, urine tests remain most accurate for recent drug use within five days.

Hair analysis is regarded as a robust method for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and other substances by preserving biomarkers within the strands as they grow. A sample taken near the scalp can offer an approximately 90-day detection span for alcohol and other substances. Hair is straightforward to gather, moderately challenging to tamper with, and easily transportable.
A sample measuring 1.5 inches, comprising about 200 hair strands (approximating the thickness of a #2 pencil), taken nearest to the scalp will yield 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or panels beyond 10, 150mg of the sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent portion of body hair may be utilized. When discussing head hair, it specifically means scalp hair solely. Body hair denotes all other hair varieties (facial, axillary, etc.).
Process Outline
The laboratory evaluation of a drug test result encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample within a lab's framework. This phase includes ensuring the sample is sealed and dispatched correctly, designating a unique LAN (Laboratory Accessioning Number), and completing any further data documentation absent from an electronic chain of custody system.
Screening comprises an initial rapid assessment for substance usage. Although Screening offers an economical method to eliminate drug consumption in most samples, any positive screening requires confirmation for judicial validity. Samples showing preliminary positive results in Screening demand secondary verification.
Should a sample yield a preliminary positive in the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. During this phase, substances are isolated from the hair at much reduced concentrations compared to other procedures (e.g., urine or oral fluid), underscoring the complexity of hair drug screening as a methodology.
Validation of any positive Screening outcome is achieved using GC/MS, GC/MS/MS or LC/MS/MS techniques. Before confirmation, presumptive positive samples undergo washing as necessary. The entire laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Constraints:
Note: Despite being colloquially labeled "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
