In Markham, Texas, Accredited Drug Testing offers comprehensive hair follicle drug testing. Whether you require hair tests for drugs or alcohol, we are experts in this domain, with facilities available nationwide, including every city, ready to conduct the tests. Hair length required is typically 1.5 to 2 inches from the crown or body, and these tests can detect drugs, alcohol/ETG, or be customized for specific needs.

There's been a notable shift towards hair follicle drug testing in recent times. Companies, legal systems, and Substance Abuse experts are increasingly opting for hair tests over traditional urine tests. Such tests are favored by zero-tolerance employers, courts, and those on probation. The long detection window of up to 90 days, coupled with an observed collection process, makes it almost impossible to tamper with. However when checking for recent drug use, urine tests still hold greater short-term accuracy.

What it is, How it works

Utilizing hair testing has become recognized as an effective means for identifying alcohol and drug consumption. Hair offers a prolonged timeline of exposure by capturing biomarkers within its growing fibers. When sourced near the scalp, hair can present a detection timeframe of approximately three months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A sample measuring 1.5 inches of roughly 200 hair strands (comparable to a #2 pencil in size) nearest the scalp provides 100mg of hair, the optimal amount for screening and confirmation. For EtG, supplementary tests, or panels over 10, a 150mg specimen is advised. We suggest utilizing a jeweler’s scale for weighing the specimen. If scalp hair is not accessible, an equivalent quantity of body hair may be gathered. When mentioning head hair, we specify scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).

Procedure Synopsis

The drug testing laboratory workflow encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample enters the lab's system, including ensuring its appropriate sealing and shipping, issuing a random LAN (Laboratory Accessioning Number), and performing any additional data entry absent from an electronic chain of custody framework.

Screening is a preliminary rapid assessment for substance abuse. Although cost-efficient for excluding drug usage in most samples, a positive screening requires confirmation for legal admissibility. Any samples presumptive of positivity in Screening necessitate successive confirmation.

For presumptive positives in the Screening stage, more hair is extracted from the original sample and prepared for Extraction. Here, drugs are isolated from hair at a substantially lower concentration compared to other methods (ex. urine or oral fluid), which contributes to the complexity of hair drug screening.

Positive screening result confirmation occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive undergo washing before confirmation as warranted. The full lab process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Benefits of hair drug tests:

  • Extended detection duration: Hair drug testing can identify drug use up to a 90-day period, contrasting with the shorter window of urine testing.
  • High resistance to deception: Cheating on a hair drug test is notably challenging, enhancing result reliability.
  • Retrospective data provision: It reveals a drug use pattern over time, instead of solely recent use.

Constraints:

  • Inability to detect recent consumption: Detection of drugs in hair typically requires 5-7 days.
  • Expense: Hair drug testing generally incurs higher costs than other methods.
  • Variability in outcomes: Factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Although sometimes dubbed "hair follicle tests," this analysis examines 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.

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.
