Accredited Drug Testing offers thorough hair follicle drug testing services in La Casita, Texas. If you require a drug or alcohol test using hair, Accredited Drug Testing excels in this method and has facilities available nationwide to perform these tests. You need 1.5 to 2 inches of hair from the scalp or elsewhere on the body if necessary. Hair tests can be used to assess drugs, alcohol/ETG, or other specific hair analysis options.

In recent times, the hair follicle drug test has become increasingly popular in drug testing procedures. Employers, courts, and Substance Abuse experts are opting for hair tests over the traditional urine tests. Hair follicle drug tests cater to zero-tolerance employers, courts, and probation individuals because of their extensive detection range, usually up to 90 days, with collection under direct supervision, making it very hard to tamper with. Nevertheless, if testing for drugs used less than five days prior is needed, urine tests remain the gold standard.

What it is, How it works

Hair testing is recognized as a robust mechanism for identifying drug and alcohol use. Hair archives a long-term record of alcohol and drugs by embedding biomarkers within the fibers of the growing strand. When cut close to the scalp, hair can reveal a detection window of up to roughly 3 months for alcohol and various drugs. Hair is easy to collect, relatively hard to tamper with, and is simple to transport.

A 1.5-inch portion of roughly 200 hairs (about as thick as a #2 pencil) nearest to the scalp will yield 100mg, the optimal sample for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is advised. We suggest weighing the specimen using a jeweler's scale. If scalp hair is lacking, an equivalent amount of body hair can be used. Head hair exclusively refers to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

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

During Accessioning, the sample is initially processed into the lab's system. This step includes verifying the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and doing any extra data entry not covered by an electronic chain of custody system.

Screening involves a preliminary swift inspection for drugs of abuse. Although Screening is a cost-effective way to exclude drug use in most samples, a positive result must be verified to be admissible in court. Any samples that test presumptively positive in Screening must undergo secondary confirmation.

For samples that are presumptively positive during Screening, more hair is extracted from the initial sample for Extraction. At this phase, drugs are extracted from the hair at substantially lower concentrations than in other methods (e.g., urine or oral fluid), which explains why hair drug screening is the most challenging method to execute.

Confirmation of any positive screening result is completed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation if needed. The full laboratory workflow from Accessioning to Confirmation is undertaken with review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extensive detection window: Hair drug tests can identify drug use up to 90 days, unlike urine tests which have shorter detection periods.
  • Hard to falsify: Cheating a hair drug test is quite difficult, ensuring higher result accuracy.
  • Offers historical insights: It provides a drug use pattern over time, not just recent consumption.

Limitations:

  • Inability to identify recent use: Drugs take about 5-7 days to become traceable in hair.
  • Expense: Hair drug tests are typically pricier than alternative drug testing techniques.
  • Result variability: Elements like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: While commonly termed "hair follicle tests," the test analyzes the strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
