Accredited Drug Testing offers comprehensive hair follicle drug testing services in Walnut Heights, California. If you require a hair drug or alcohol test, Accredited Drug Testing has expertise in hair testing and operates testing centers nationwide capable of conducting a hair analysis. Typically, 1.5 to 2 inches of hair from your head's crown or another body area is necessary. Hair tests can be tailored to detect drugs, alcohol/ETG, or other specific substances.

In recent times, hair follicle drug testing has become increasingly prevalent for drug screenings. Many employers, legal authorities, and substance abuse experts now favor hair drug tests over traditional urine tests. Hair follicle drug tests are utilized by businesses with strict no-drug policies, judicial systems, and individuals on probation. The main advantage of hair follicle drug tests is their extended detection period, typically up to 90 days, captured through a supervised collection method, making them nearly impossible to tamper with. However, for detecting drug use within the past 5 days, urine tests remain the most precise.

What it is, How it works

Hair analysis is now acknowledged as an effective technique for identifying substance and alcohol consumption. Hair captures extended-term markers of alcohol and drug usage by embedding biomarkers within the strands of growing hair. When extracted near the scalp, hair may offer an observation period of up to roughly 3 months for substances like alcohol and drugs. Collecting hair is straightforward, difficult to tamper with, and convenient to transport.

A sample measuring 1.5 inches of around 200 hairs (approximate thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for both screening and validation. For tests like EtG, add-ons, and those exceeding 10 panels, a quantity of 150mg is advised. We recommend using a jeweler’s scale to weigh the sample. If head hair is absent, a similar quantity of body hair may be gathered. By ‘head hair’, we specifically mean scalp hair. Body hair denotes all other types like facial or axillary hair.

Procedure Synopsis

The key stages in laboratory evaluation of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary management of a sample into a lab's framework, which involves checking that the sample was correctly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data input not offered by an electronic chain of custody method.

Screening represents an initial rapid assessment for prohibited substances. While Screening is a budget-friendly approach to dismiss drug consumption in most samples, any positive Screening finding needs verification for it to be valid legally. Any samples with a presumptive positive result during Screening necessitate subsequent confirmation.

Should a sample yield a presumptive positive in the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. In this process, substances are isolated from hair at concentrations significantly lower than other techniques (such as urine or oral fluids), underscoring why hair drug analysis is notably complex to conduct.

Confirmation for any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples are cleansed before the confirmation if needed. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the credentialing to ISO / IEC 17025 criteria.

Pros of hair drug testing:

  • Extended detection duration: Hair drug analyses can identify narcotics use up to 90 days, unlike urine tests with a more limited detection timeframe.
  • Hard to subvert: It's notably challenging to falsify a hair drug analysis, thereby ensuring greater accuracy of outcomes.
  • Yields historical insights: It can reveal a pattern of narcotics usage over time, rather than just recent consumption.

Drawbacks:

  • Cannot spot recent intake: It typically requires 5-7 days for substances to become discernible in hair.
  • Expense: Hair drug analyses often incur higher costs compared to alternate testing methods.
  • Result variances: Elements like hair color and personal variations in hair growth may influence the concentration of drug metabolites within the hair.

Note: While colloquially termed "hair follicle tests", the assessment examines the hair strand itself, and not the follicle beneath the scalp.
