Accredited Drug Testing offers extensive hair follicle drug testing in St. Paul Park, Minnesota. For individuals requiring a hair drug or alcohol test, Accredited Drug Testing is a leader in hair testing, with locations nationwide capable of conducting such tests. A minimum of 1.5 to 2 inches of hair is typically necessary, either from the scalp or body. Hair samples can be evaluated for drugs, alcohol/ETG, or other specific testing needs.
In recent years, hair follicle drug testing has increasingly become a preferred method for drug screening. Employers, judicial systems, and substance abuse specialists are opting for hair tests over traditional urine tests. Employers enforcing stringent drug policies, courts, and probationers lean on hair tests, which offer a detection window of up to 90 days and are virtually cheat-proof. Despite this, urine tests remain more precise for detecting recent drug use within the last 5 days.

Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug usage by embedding biomarkers within the strands of hair as they grow. When samples are taken near the scalp, they can indicate substance use over an approximate three-month period. The collection of hair is straightforward, relatively tamper-proof, and convenient for shipping.
By obtaining a 1.5-inch section containing around 200 hair strands (roughly the width of a #2 pencil) from near the scalp, approximately 100mg of hair can be secured, which is the ideal amount for screening and confirmation purposes. For EtG, additional testing, and tests exceeding 10 panels, a sample of 150mg is preferable. We advise using a jeweler’s scale for weighing the specimen. If scalp hair is unobtainable, an equal volume of body hair might be used. Reference to head hair specifically signifies scalp hair, while body hair denotes all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the foundational step of integrating a sample into the lab’s system. This step involves confirming that the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry missing from an electronic chain of custody.
Screening means an initial cursory examination for substances of abuse. Although Screening is economically efficient for excluding drug usage in the majority of cases, a positive result on this initial check must be confirmed to hold up in legal proceedings. Samples showing a presumptive positive result during Screening must undergo a confirmatory test.
In instances where a sample tests presumptively positive during Screening, additional hair is drawn from the initial sample for the Extraction phase. During Extraction, drugs are isolated from hair at significantly lower concentrations compared to other testing methods like urine or oral fluid, which contributes to the complexity of hair drug screening.
Confirmation for any sample with a positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity undergo washing before confirmation if necessary. The full lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although sometimes termed "hair follicle tests," the examination actually focuses on the hair strand rather than the follicle beneath the scalp.
