Accredited Drug Testing provides comprehensive hair follicle drug testing solutions in Columbia, Iowa. With specialization in hair drug and alcohol tests, we operate testing facilities across all cities nationwide equipped to conduct hair testing. Typically, 1.5 to 2 inches of hair from the head or body suffices for the test. Hair tests encompass analyses for drugs, alcohol/ETG, along with other tailored testing options.
Recently, the approach to drug testing is increasingly leaning towards hair follicle testing. This method is now preferred by employers, courts, and substance abuse counselors over traditional urine tests. Hair follicle drug tests are typically requested by employers with strict no-drug policies, court systems, and those managing probation cases. The key advantage of hair tests is their extended detection window, usually covering up to 90 days, collected through an observed method, making cheating nearly impossible. However, urine tests remain the gold standard for recent drug use, within the past 5 days.

Hair analysis has emerged as a significant method for detecting drug and alcohol consumption. Hair records a long-term record of substances by embedding biomarkers in the strands of growing hair. Harvested near the scalp, hair can offer an approximately three-month detection period for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch portion consisting of roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest the scalp will yield 100mg, which is the ideal quantity for analysis and validation. For EtG, supplementary tests, and/or examinations exceeding 10 panels, it's optimal to have 150mg of the sample. Utilizing a jeweler’s scale for weighing is advisable. If scalp hair isn't available, you can use an equivalent amount of body hair. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair forms (facial, axillary, etc.).
Process Overview
There are four primary steps within the lab processing for a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a specimen into a lab’s system. This step involves ensuring the sample was correctly sealed and dispatched, assigning it a unique LAN (Laboratory Accessioning Number), and completing any further data entry not captured by an electronic chain of custody system.
Screening is a preliminary rapid analysis for substances of abuse. Although Screening is a cost-effective method to exclude drug use for most samples, any positive result from this stage needs affirmation to be legally tenable. Presumed positive samples in Screening do need a confirmation step.
Samples assumed to be positive after Screening will undergo Extraction, where more hair is prepared from the original sample. This phase strips drugs from hair at a notably lower concentration compared to other techniques (e.g., urine or saliva), illustrating why hair drug testing is notably complex.
Confirmation of any presumptive positive outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples are cleansed as necessary before confirmation. The full laboratory procedure from Accessioning to Confirmation is overseen under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed as "hair follicle tests", these tests analyze the hair strand rather than the scalp-level hair follicle.
