Accredited Drug Testing offers thorough hair follicle drug assessments in Colby, Wisconsin. For those requiring a hair drug or alcohol screening, we specialize in such tests and maintain facilities nationwide to accommodate these needs. Typically, 1.5 to 2 inches of hair is necessary from the crown or body. These tests can determine drug, alcohol/ETG presence or be tailored for specific needs.

Hair follicle drug testing has become a preferred method for screening substance use. Many employers, legal systems, and substance abuse experts are opting for it over urine tests. Employers enforcing zero-tolerance policies, judicial bodies, and probationary individuals choose this method primarily due to its extended detection window of up to 90 days, reliability, and resistance to manipulation. For identifying drug use within the past 5 days, urine tests remain the most precise.

What it is, How it works

Recognized as an effective method for identifying substance use, hair testing provides an extended timeline for detecting alcohol and drug presence by capturing indicators within the strands. When sourced near the scalp, hair offers a detection range of up to 3 months for such substances. Collecting hair is straightforward, challenging to tamper with, and convenient for transport.

A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to the girth of a #2 pencil) from the scalp yields 100mg, which is optimal for both screening and verification. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure this on a jeweler’s scale. In the absence of scalp hair, collecting a similar quantity from body hair is an option. When discussing head hair, we focus solely on scalp hair. Body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The key phases in lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is concerned with the preliminary assimilation of a sample into the lab's system. This step involves confirming the sample’s seal and shipment accuracy, assigning it a random LAN (Laboratory Accessioning Number), and completing any data entry that was not supplied by an electronic chain of custody system.

Screening is a preliminary drug abuse assessment. Although cost-effective in excluding drug use for most samples, a positive screen necessitates confirmation for legal proceedings. Any samples that show potential positivity in Screening require additional confirmation.

Should a sample exhibit potential positivity during Screening, further hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from the hair at significantly lower concentrations relative to other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.

Confirmation of any positive findings from Screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All potentially positive samples undergo necessary washing before confirmation. The entire lab procedure from Accessioning through Confirmation undergoes scrutiny under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditations.

Benefits of hair drug testing:

  • Extended detection period: Hair drug tests identify drug use over up to 90 days, unlike urine tests that have a shorter detection timeframe.
  • Difficult to manipulate: It is exceedingly challenging to falsify the results of a hair drug test, thus enhancing result accuracy.
  • Offers historical insights: Hair testing can indicate patterns of drug use over time rather than recent use only.

Drawbacks:

  • Cannot identify recent use: A period of approximately 5-7 days is needed before drugs become detectable in hair.
  • Expense: Hair drug tests are typically pricier than alternative drug testing methods.
  • Result variability: Elements like hair color and individual differences in hair growth can impact drug metabolite levels in hair.

Note: The tests often called "hair follicle tests" actually evaluate the hair strand, not 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. Results are provided in a form that can be reviewed by legal and administrative authorities.
Yes. Individuals, parents, attorneys, employers, and probation programs can all request hair drug testing. A doctor's order is not required. Results are confidential and released only to the authorized requesting party.
Hair testing provides a longer look-back period than urine testing, making it useful when you need to demonstrate ongoing abstinence or identify repeated/recent substance use patterns over time rather than just recent exposure. It is frequently selected for legal, compliance, and custody-related documentation.
A small section of hair is cut by a trained collector in a discreet, controlled manner. The sample is sealed, documented, and sent to the laboratory under established chain-of-custody procedures so that the results can be defended if they are ever challenged.
