Accredited Drug Testing offers comprehensive hair follicle drug testing services in Leonard, Michigan. Whether you require testing for drugs or alcohol, our expertise lies in hair testing, available in numerous testing centers across the nation. Having 1.5 to 2 inches of hair on the head or body is typically necessary. Hair tests can evaluate drugs, alcohol/ETG, or other personalized testing needs.

Increased reliance on hair follicle testing for drug screening is evident among employers, courts, and Substance Abuse professionals, who often prefer it over standard urine tests. Employers with strict drug use policies, judicial systems, and probation officers find hair tests valuable for their extensive detection period, spanning up to 90 days, and their resistant nature to tampering. Yet, for recent drug use detection within the past 5 days, urine tests remain the most precise.

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair captures a comprehensive history of substance use by embedding biomarkers within its growing strands. When taken close to the scalp, hair can indicate drug and alcohol usage over an approximate three-month period. Its collection is easy, it's relatively hard to tamper with, and it can be shipped with ease.

A 1.5-inch sample comprising around 200 hair strands (roughly the dimensions of a #2 pencil) nearest to the scalp will yield 100mg of hair, the recommended sample size for screening and validation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample size is suggested. Using a jeweler's scale for weighing is advisable. If scalp hair is unavailable, an equivalent amount of body hair is acceptable. When mentioning head hair, we imply scalp hair exclusively. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The core stages in lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses integrating a specimen into a lab's system. This involves ensuring the sample was correctly sealed and posted, issuing a unique LAN (Laboratory Accessioning Number), and completing any extra data input missing from an electronic chain of custody record.

Screening is a preliminary swift inspection for potential drug use. Although Screening is a cost-efficient method to dismiss drug usage in most specimens, a positive screening result must be authenticated for legal admissibility. Samples that are tentatively positive in Screening necessitate further confirmation.

In cases of presumptive positive results during Screening, additional hair is retrieved from the initial sample and prepped for Extraction. This phase involves drawing out drugs from hair at significantly lower concentrations than alternative methods (e.g., urine or saliva), underscoring why hair drug testing is notably challenging.

Validating any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS processes. All samples indicating potential positivity are cleaned before confirmation as necessary. The entire lab procedure, from Accessioning through Confirmation, is subject to evaluation under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Prolonged detection capability: Hair drug screening identifies drug consumption for as long as 90 days, unlike urine screenings with more limited detection spans.
  • Resistance to manipulation: Hair drug tests are notably difficult to manipulate, thereby enhancing result accuracy.
  • Insight into substance history: It provides insight into drug use patterns over time, beyond immediate consumption.

Limitations:

  • Inability to detect recent use: It takes about 5-7 days for drugs to show up in hair samples.
  • Expense: Hair drug examinations often incur higher costs compared to other drug test techniques.
  • Result variability: Elements such as hair pigmentation and individual growth variation can influence metabolite concentration in hair.

Note: Despite being popularly called "hair follicle tests," the analysis targets the strand itself 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.
