Trusted Drug Testing offers comprehensive hair follicle drug testing in San Marcos, Texas. For those needing a hair drug or alcohol screening, Trusted Drug Testing focuses on hair analysis with facilities across the country ready to perform the tests. Generally, 1.5 to 2 inches of hair from the crown or body can be used. These tests are evaluated for drugs, alcohol/ETG, or tailored testing solutions.

Recently, drug testing methods have increasingly adopted hair follicle tests. Employers, courts, and those in Substance Abuse treatment frequently require hair tests over traditional urine analyses. These tests are favored by entities with strict no-drug policies, and for probationary oversight. The main advantage is its extended detection time, which can reveal drug use up to 90 days, is monitored during collection, and is nearly impossible to adulterate. However, for detecting recent drug use within 5 days, urine tests remain the most precise.

* 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 testing is now recognized as a potent method for identifying drug and alcohol consumption. Hair captures a comprehensive history of alcohol and other drugs by embedding biomarkers in its growing strands. When harvested near the scalp, hair may reveal an up to three-month window of alcohol and drug usage. Hair collection is straightforward, challenging to tamper with, and convenient to send.

A 1.5-inch section totaling approximately 200 hair strands (similar in size to a #2 pencil) from nearest the scalp yields 100mg of hair, the optimal quantity for screening and verification. For EtG, supplementary, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to measure the sample. If scalp hair isn't accessible, an equivalent quantity of body hair can be collected. When we mention head hair, we refer exclusively to scalp hair. Body hair encompasses all other hair types (like facial or axillary hair).

Process Overview

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

Accessioning includes the initial input of a sample into a lab’s system. This process involves checking that the sample was adequately sealed and delivered, allotting a random LAN (Laboratory Accessioning Number), and fulfilling any additional data not handled by an electronic chain of custody system.

Screening offers a rapid assessment for substances of abuse. Although Screening is an economical means of negating drug consumption for most samples, a positive result needs confirmation to be legally acceptable. Any samples showing a presumptive positive from Screening must undergo additional confirmation.

Should a sample display a presumptive positive during Screening, more hair is drawn from the primary sample and processed for Extraction. Here, drugs are extracted from hair at much lower densities compared to other techniques (e.g., urine or oral fluid), which makes hair drug screening one of the most challenging methodologies to execute.

Affirmation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation if necessary. The full lab process, from Accessioning through Confirmation, is vetted under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection span: Hair drug tests can discover drug intake for up to 90 days, unlike urine tests with a shorter detection range.
  • Hard to deceive: Cheating a hair drug test is exceedingly difficult, enhancing result accuracy.
  • Delivers past data: It can outline a drug usage pattern over time, beyond just recent intake.

Limitations:

  • Incapable of detecting recent intake: Approximately 5-7 days are needed for drugs to manifest in hair.
  • Expense: Generally, hair drug tests have a higher cost than other testing methods.
  • Result variability: Elements like hair color and individual hair growth can impact the concentration of drug metabolites in hair.

Note: Although often called "hair follicle tests," the analysis is conducted on the hair strand itself, not the follicle beneath the scalp.
