In Donnellson, Iowa, Accredited Drug Testing offers comprehensive hair follicle drug testing. Whether it's for drug or alcohol detection, we specialize in hair testing and have centers nationwide equipped to conduct these tests. Typically, 1.5 to 2 inches of hair are needed from the crown or, in some cases, body hair can be used. These tests can check for drugs, alcohol/ETG, or other tailored hair testing options.
The adoption of hair follicle drug tests has increased among employers, courts, and substance abuse experts in recent years, often replacing traditional urine tests. Hair tests are favored by those enforcing zero-tolerance policies and for probation monitoring. They provide a detection window of up to 90 days and are collected under observation, making tampering nearly impossible. However, urine tests remain most accurate for recent drug use within 5 days.

Hair tests are increasingly regarded as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug intake by embedding biomarkers within the hair’s growing strands. When taken near the scalp, hair can offer a detection period of nearly three months for drugs and alcohol. Hair is straightforward to collect, not easily tampered with, and simple to transport.
A 1.5-inch segment containing roughly 200 hairs (around the diameter of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. We suggest utilizing a jeweler's scale to measure the specimen. Should scalp hair be unattainable, a similar volume of body hair is acceptable. Specifically referring to head hair pertains solely to scalp hair. Body hair encompasses all other varieties (such as facial, axillary, etc.).
Process Overview
The primary stages involved in processing a drug test in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial introduction of a specimen into the lab's system. This step confirms the specimen was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and fills in any data gaps not addressed by an electronic chain of custody system.
Screening performs an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient approach to exclude drug usage in most specimens, a confirmed result is necessary for court acceptance. Any samples that show presumptive positivity during Screening demand subsequent confirmation.
If a specimen shows presumptive positivity in the Screening phase, additional hair is retrieved from the initial sample for Extraction. This phase involves extracting drugs from hair at concentrations significantly lower than those in other methods (such as urine or oral fluids), which is why hair drug tests are among the most complex to conduct.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive are cleansed before confirmation if needed. The complete lab process from Accessioning through Confirmation is overseen under both the CAP (College of American Pathologists) Hair program and accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Despite being often called "hair follicle tests", the test evaluates the hair strand, not the follicle beneath the scalp.
