Accredited Drug Testing offers comprehensive hair follicle drug testing services in Merit, Texas. If you require a drug or alcohol test involving hair, our expertise lies in this area, with centers nationwide capable of administering the test. At least 1.5 to 2 inches of hair on your head or body can be used. Hair tests can be analyzed for drugs, alcohol/ETG, or tailored hair testing choices.

In recent years, the reliance on hair follicle drug tests has risen among drug testing methods. They are increasingly preferred by employers, courts, and Substance Abuse specialists over traditional urine tests. These tests are favored by zero-tolerance employers, legal systems, and probation overseers. The key advantage of hair tests is their extended detection period of up to 90 days, ensuring observation during collection and making it nearly impossible to tamper with. However, for detecting recent drug use within the past 5 days, urine tests remain the most precise.

What it is, How it works

Hair analysis is recognized as an effective strategy for discovering drug and alcohol consumption. Hair captures a prolonged history of substances by embedding markers within the growing strand's fibers. When taken from near the scalp, hair offers up to an estimated 3-month detection timeframe for various substances. Hair is convenient to collect, challenging to tamper with, and straightforward to transport.

A sample of 1.5 inches, approximately 200 strands (equivalent to a #2 pencil's thickness), gathered close to the scalp provides 100mg, which is the ideal amount for initial testing and confirmation. For tests involving EtG, additional tests, or those exceeding ten panels, 150mg is suggested. Using a jeweler’s scale to measure the sample is advisable. If scalp hair isn't accessible, a comparable quantity of body hair can be collected. References to head hair specifically indicate scalp hair. Body hair encompasses all other types (such as facial or axillary hair).

Process Overview

The key four stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the primary processing of a sample into the lab’s workflow. This step involves checking that the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry not covered by an electronic chain of custody system.

Screening is an initial quick analysis for drug use. While it’s a cost-efficient method to dismiss usage in most samples, a screen yielding a positive result must be confirmed for court acceptability. Samples showing presumptive positives in Screening necessitate secondary verification.

Should Screening suggest a positiva sample, more hair is taken from the original batch and prepared for Extraction. In this phase, drugs are removed from hair in lower concentrations compared to other methods (like urine or oral fluid), making hair drug testing the most challenging procedure.

Confirmed screenings follow through GC/MS, GC/MS/MS, or LC/MS/MS analyses. Any samples indicating presumptive positives undergo cleaning before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation is assessed in alignment with the CAP (College of American Pathologists) Hair guidelines and certification in agreement with ISO / IEC 17025 criteria.

Advantages of hair drug testing:

  • Extended detection: Hair drug tests trace drug use up to 90 days, unlike urine tests which have shorter timeframes.
  • Hard to falsify: Cheating a hair drug test is highly difficult, ensuring more precise results.
  • Historical insights: Offers insights into usage patterns over an extended period, not only recent consumption.

Limitations:

  • Recent usage undetectable: Drugs take roughly 5-7 days to appear in hair.
  • Expense: Generally, hair drug tests come with higher costs compared to other methods.
  • Result variability: Variables like hair color and personal differences in hair growth influence metabolite concentrations in hair.

Note: Despite being termed as "hair follicle tests", the assessment evaluates the strand of hair, not the follicle located under the scalp.
