In Novato, California, Accredited Drug Testing offers a full array of hair follicle drug testing services. Whether you require a hair drug or alcohol test, our specialization lies in hair testing. We have established testing facilities across all cities in the US that can conduct these tests. Typically, 1.5 to 2 inches of hair from your head or body is required. Our hair tests are capable of analyzing drugs, alcohol/ETG, or offering tailored hair testing solutions.

The preference for drug testing procedures has increasingly leaned towards hair follicle drug testing in recent years. This switch is driven by demands from employers, judicial systems, and substance abuse experts who favor hair tests over traditional urine tests. Companies with zero-tolerance drug policies, courts, and probation services often mandate hair follicle tests. One significant advantage of hair testing is its extended detection span, generally covering up to 90 days, coupled with an observed collection process that makes cheating nearly impossible. Despite this, urine tests retain their accuracy for detecting recent drug use within the preceding five days.

What it is, How it works

Hair analysis is regarded as a robust method for identifying drug and alcohol consumption. Hair captures a chronological record of substances by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can offer a detection period extending up to three months for alcohol and drugs. Hair is easy to gather, difficult to tamper with, and convenient to mail.

A 1.5-inch segment comprising roughly 200 hair strands (approximately equivalent to the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is the ideal quantity for both initial screening and confirmation. For EtG, additional tests, or those surpassing 10 panels, a specimen of 150mg is advisable. We suggest weighing the sample with a jeweler’s scale. If scalp hair is absent, an equivalent quantity of body hair can be obtained. When discussing head hair, it refers exclusively to scalp hair. Body hair encompasses other types (facial, underarm, etc.).

Procedure Overview

The primary components of laboratory processing for drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory's system. This entails verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data recording not provided by an electronic chain of custody system.

Screening offers a preliminary examination for drugs. Although Screening is an economical method to exclude drug usage in the majority of samples, a confirmed positive screen is necessary for legal validity. Samples that result presumptively positive in Screening require secondary confirmation.

If the Screening process suggests a positive result, additional hair from the initial sample is prepared for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is more challenging to conduct.

Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed as necessary prior to confirmation. The complete laboratory procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Benefits of hair drug analysis:

  • Extended detection period: Hair drug tests are capable of identifying drug use for as long as 90 days, compared to urine tests with shorter detection durations.
  • Resistance to falsification: Cheating a hair drug test is exceptionally challenging, enhancing result accuracy.
  • Historical data provision: Allows for tracking patterns of drug usage over time, not just recent usage.

Constraints:

  • Inability to detect recent use: Approximately 5-7 days are required for drugs to become apparent in hair.
  • Expense: Hair drug tests tend to be pricier than alternative drug testing methods.
  • Result variability: Aspects such as hair color and individual differences in hair growth can influence metabolite concentration within hair.

Note: While often termed "hair follicle tests", the test evaluates the hair strand rather than 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.
