Accredited Drug Testing provides thorough hair follicle drug tests in La Salle, Minnesota. If you require drug or alcohol tests via hair samples, our centers nationwide are equipped to facilitate this. A minimum of 1.5 to 2 inches of hair on the head or body can be used typically. These hair tests can detect drugs, alcohol/ETG, or be customized for specific testing needs.
Recently, drug testing reliably employs hair follicle tests more frequently. Employers, courts, and Substance Abuse professionals are opting for hair tests over traditional urine tests. Hair tests are favored by zero-tolerance employers, the legal system, and probationers. Hair tests offer a longer detection window for drug use, around 90 days, ensuring an observed collection process that's hard to tamper with. However, for detecting very recent drug use, within five days, urine tests remain more precise.

Employing hair testing is recognized as an effective approach for identifying alcohol and drug consumption. Hair carries a prolonged record of substances by embedding biomarkers within the strands as they grow. When collected near the scalp, it can offer nearly a 3-month detection timeframe for alcohol and drugs. Hair sampling is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch section consisting of roughly 200 hairs (approximately the girth of a #2 pencil) closest to the scalp provides 100mg, ideal for screening and verification. For EtG, additional tests, and/or over 10-panel tests, a specimen of 150mg is advisable. It is recommended to weigh the specimen with a jeweler’s scale. If scalp hair isn’t available, an equivalent amount of body hair may be used. When we refer to head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (such as facial and axillary).
Process Overview
The lab processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the initial integration of a sample into a lab's database, which includes verifying proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not included in an electronic custody chain.
Screening involves a preliminary assessment for drug presence. While it’s a cost-friendly method to exclude drug usage in most samples, a positive result requires confirmation for court admissibility. Any samples showing presumptive positives in Screening need subsequent confirmation.
Should a sample show presumptive positivity during Screening, more hair is extracted from the specimen and prepared for Extraction. In this stage, drugs are retrieved from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is the hardest method to execute.
If a screening yields a positive, verification is done using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are washed before confirmation when necessary. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and certification to ISO / IEC 17025 standards.
