Accredited Drug Testing offers comprehensive hair follicle drug testing in Sealy, Texas. If you're in need of a hair drug or alcohol test, we specialize in this method, with testing centers available in every city across the nation capable of conducting a hair test. Typically, you'll need 1.5 to 2 inches of hair from the crown of your head or body. Hair tests can detect drugs, alcohol/ETG, or other specific testing options.

In recent years, drug testing methods have increasingly included the hair follicle drug test. More employers, courts, and Substance Abuse professionals are opting for a hair drug test over the standard urine test. Hair follicle drug tests are preferred by employers with zero-tolerance drug policies, as well as courts and individuals on probation. The key advantage of a hair follicle drug test is the extended detection period for drug use, typically up to 90 days, collected under observation, making it nearly impossible to tamper with. However, for drug use detection within the past 5 days, urine tests remain the most accurate.

What it is, How it works

Hair analysis is regarded as a proficient approach for identifying drug and alcohol consumption. Hair offers a prolonged timeline of alcohol and substance usage by embedding biomarkers within the fibers of growing strands. When sampled near the scalp, hair can reveal a detection span of roughly three months for drugs and alcohol. Hair collection is straightforward, resistant to tampering, and easily transportable.

A 1.5-inch segment comprising nearly 200 strands (roughly equivalent to a #2 pencil) nearest the scalp yields 100mg, the optimal sample size for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg quantity of the sample is advised. It’s suggested to use a jeweler’s scale for weighing the sample. If scalp hair is insufficient, a similar quantity of body hair can be utilized. “Head hair” exclusively denotes scalp hair, whereas “body hair” encompasses all other hairs (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase includes the sample’s initial assimilation into a lab’s system, corroborating that it was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and executing any supplemental data entry not fulfilled by an electronic chain of custody protocol.

Screening entails a preliminary rapid evaluation for drugs of abuse. Although Screening efficiently eliminates negative samples, a positive result mandates confirmation for court validity. Any samples testing presumptively positive in the Screening phase require secondary confirmation.

Specimens deemed presumptively positive during Screening undergo additional hair extraction from the original sample for the Extraction procedure. Here, drugs are extracted at substantially reduced concentrations compared to other techniques (such as urine or oral fluid), rendering hair drug screening particularly intricate to conduct.

Positive screening confirmations are executed via GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are washed prior to confirmation if necessary. The complete laboratory sequence from Accessioning to Confirmation adheres to scrutiny under both the College of American Pathologists (CAP) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can identify drug usage for as long as 90 days, unlike urine tests that have shorter detection spans.
  • Cheating is challenging: The ability to falsify results in a hair drug test is minimal, ensuring greater accuracy.
  • Defines historical usage: Offers insights into patterns of drug use over time, not just recent consumption.

Limitations:

  • Inability to identify recent usage: Drugs become detectable in hair after approximately 5-7 days.
  • Expense: Hair drug tests generally incur more costs compared to alternative drug testing approaches.
  • Result variability: Elements like hair color and individual hair growth rates can impact the metabolite concentration in hair.

Note: The term "hair follicle tests" is a misnomer, as the test examines 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.
