Schedule your Hair Drug Test

Employment, Court Ordered, Probation, Family

In San Carlos, Texas, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Specializing in this field, we provide testing centers nationwide. For a hair test, a sample length of 1.5 to 2 inches is typically needed, either from the head or body. These tests can screen for drugs, alcohol/ETG, and other tailored options.

Over recent years, hair follicle drug tests have become a favored method for substance testing. Employers and legal entities prefer hair tests over urine tests for stricter drug policies. Hair testing offers an extensive detection period of up to 90 days, is conducted under observation, and is difficult to falsify. Nonetheless, urine tests remain the most precise for identifying recent drug use within a five-day timeframe.

* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.

What it is, How it works

Hair analysis is recognized as a potent method for identifying the consumption of drugs and alcohol. It offers a long-term record by capturing biomarkers within the fibers of the hair as it develops. When obtained close to the scalp, hair can reveal a detection period of up to roughly three months for substances including alcohol. The method is easy to perform, somewhat resistant to tampering, and convenient to transport.

Collecting a 1.5-inch segment of roughly 200 hairs (approximately equivalent to the size of a #2 pencil) nearest the scalp yields 100mg of hair, the preferred amount for both screening and verification. For EtG, additional tests, or assessments exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair isn't available, the same quantity of body hair can be utilized. The term head hair refers to scalp hair only, while body hair encompasses all other kinds (such as facial and axillary).

Process Overview

The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first phase, involving the introduction of a sample into the laboratory’s system. This step ensures the sample was securely sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry not covered by an electronic chain of custody system.

Screening provides an initial rapid assessment for illicit substances. As an affordable method, Screening can rule out most drug use; however, a positive result must be verified for legal admissibility. Samples testing positive in Screening require a secondary confirmation.

Should a specimen screen positive, additional hair from the initial sample is extracted for further processing. At this stage, drugs are withdrawn from hair at a lower concentration compared with other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

The Confirmation step, essential for any positive screening result, utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, samples that are presumptively positive are washed as required. A thorough review of the entire laboratory process from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can identify drug usage up to 90 days in contrast to the shorter detection span of urine tests.
  • Hard to falsify: The accuracy of hair drug tests is enhanced by the difficulty of tampering.
  • Provides usage history: Beyond recent drug intake, it offers a timeline of patterns over time.

Limitations:

  • Recent use undetectable: It typically takes 5-7 days for substances to appear in hair.
  • Expense: Hair tests usually cost more than other forms of drug tests.
  • Result variation: Variables such as hair color and personal hair growth can influence drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests," the analysis actually involves the hair strand and not the follicle beneath the skin.
