In Granville, Iowa, Accredited Drug Testing offers a comprehensive hair follicle drug testing service. For those requiring hair drug or alcohol tests, our specialized team is available in various cities nationwide. Typically, hair measuring between 1.5 to 2 inches from the scalp or other body parts can be utilized. We provide analyses for drugs, alcohol/ETG, and other tailored hair testing services.

The popularity of hair follicle drug tests has increased in recent years. Employers, courts, and Substance Abuse professionals now frequently opt for this method over traditional urine tests. Those with zero-tolerance drug use policies, as well as court-mandated programs, prefer hair tests for their extended detection window—up to 90 days—and their nearly cheat-proof nature. Despite this, urine tests remain the most accurate when detecting drug use within the last 5 days.

What it is, How it works

Hair assessment is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, providing an extended record of substance use. When hair is cut close to the scalp, it can reveal drug and alcohol consumption for a period of roughly 3 months. Hair is easy to gather, hard to tamper with, and straightforward to transport.

A cutting of 1.5 inches, consisting of about 200 hair strands (comparable in size to a #2 pencil) near the scalp, yields 100mg of hair, which is the optimal sample size for both screening and verifying. For EtG extensions or tests exceeding 10 panels, a specimen of 150mg is advised. It is best to weigh the sample with a jeweler's scale. If scalp hair is not accessible, a similar amount of body hair can be used. "Head hair" specifically references scalp hair. Conversely, "Body hair" pertains to all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the preliminary processing of a sample into a lab's system, ensuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and entering any additional data not included by an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of abuse. Although Screening is an economical means of excluding drug use in most samples, any positive finding requires confirmation for judicial acceptability. Samples with presumptive positives in Screening are obligated to undergo subsequent verification.

Should a sample show presumptively positive results during Screening, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are separated from hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging technique to execute.

Positive preliminary screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to Confirmation, all samples identified as presumptive positives are cleansed as required. The complete lab process, spanning from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection span: Hair drug tests reveal drug use for up to 90 days, whereas urine tests have a shorter detection span.
  • Challenging to tamper: Cheating a hair drug test is arduous, leading to more reliable outcomes.
  • Offers historical insight: It can illustrate a drug use pattern over time, rather than only recent use.

Limitations:

  • Inability to detect recent usage: It takes about 5-7 days for drugs to appear in hair.
  • Expense: Hair drug tests are typically pricier than alternate drug testing techniques.
  • Outcome variability: Elements such as hair color and individual hair growth disparities can influence the drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests", the analysis is performed on the hair strand rather than the follicle beneath the scalp.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
Yes. If the donor's head hair is too short or unavailable, body hair may be collected as an alternative. The collector will document the source of the sample. This allows testing even for individuals with recently cut or shaved head hair.
Yes. Hair drug testing is commonly used in court, probation, custody, and compliance matters because the collection process follows a documented chain of custody and the analysis is performed by a certified laboratory.
