Employment, Court Ordered, Probation, Family

Accredited Drug Testing provides comprehensive hair follicle drug testing services in Loretto, Minnesota. For those needing hair drug or alcohol tests, we excel in hair testing and have facilities located in all cities across the nation to conduct these tests. Usually, 1.5 to 2 inches of hair from the scalp or body is required. Our hair tests can detect drugs, alcohol/ETG, or other customized testing solutions.

Lately, the trend in drug testing has increasingly involved using hair follicle tests. Employers, legal authorities, and Substance Abuse professionals now often prefer hair drug tests over traditional urine tests. Hair follicle tests cater to employers with strict no-drug policies, legal systems, and individuals on probation. A key advantage is the extended detection duration, reaching up to 90 days, through observed collections, making tampering nearly impossible. However, for drug use screening within a 5-day window, urine testing remains the gold standard.

What it is, How it works

Hair examinations are widely acknowledged as an effective method for identifying drug and alcohol consumption. Hair strands encapsulate biomarkers within their fibers, offering a long-term record of substance use. When procured near the scalp, hair can provide an approximate detection span of three months for substances. It is straightforward to gather, challenging to tamper with, and convenient to transport.

A strand sample of 1.5 inches and roughly 200 hairs (comparable to a #2 pencil in size) near the scalp will produce 100mg of hair, which is perfect for both screening and verification. For EtG, additional tests, or testing beyond 10 panels, 150mg is advised. Utilization of a jeweler’s scale for specimen weighing is recommended. In case scalp hair is lacking, an equal collection of body hair is acceptable. When we mention head hair, we mean only scalp hair. Body hair includes all other types like facial or axillary hair.

Process Overview

The laboratory procedure to process a drug test outcome comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introductory step where a sample is logged into a lab's system. This step verifies the sample's sealing and shipping appropriateness, assigns a random Laboratory Accessioning Number (LAN), and fills in additional data not covered by an electronic chain of custody system.

Screening is an expedited check for drug misuse. Despite being cost-efficient for ruling out drug use in most cases, a positive screen has to be verified to stand in legal contexts. Any samples suspected as positive in Screening necessitate secondary affirmation.

For samples indicating a presumptive positive during Screening, further hair is extracted from the original specimen for Extraction. This procedure extracts drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is the most challenging approach.

Confirmation for any positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS methods. All preliminary positive samples undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is overseen under the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standards accreditation.

Advantages of hair drug testing:

  • Extended detection duration: Hair drug examinations can reveal substance use spanning up to 90 days, unlike urine examinations that detect drug usage over a shorter span.
  • Hard to falsify: Cheating on a hair drug examination is nearly impossible, enhancing result accuracy.
  • Shows historical substance use: It depicts substance use patterns over time instead of just recent usage.

Limitations:

  • Cannot identify recent usage: Drugs become detectable in hair after about 5-7 days.
  • Higher costs: Hair drug examinations are typically more costly than other testing methods.
  • Results may vary: Aspects like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Loretto, MN, hair follicle testing surpasses urine testing in effectiveness and reliability. While urine tests are limited by a short detection window, hair tests track substance usage over a 90-day span, delivering unparalleled insights.

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.
