Accredited Drug Testing offers full-service hair follicle drug testing in Belvedere, CA. For those needing a drug or alcohol hair test, our specialized centers provide hair testing across all major cities nationwide with proficiency in conducting hair tests. Generally, 1.5 to 2 inches of hair from the scalp or body can be used. Hair testing can detect drugs, alcohol/ETG, or be tailored for other specific hair analysis.

Nowadays, hair follicle drug testing has become more prevalent in drug screening methods. Employers, legal courts, and substance abuse professionals now frequently opt for hair drug tests over traditional urine tests. Organizations with zero-tolerance policies, legal systems, and probation services rely on hair follicle screenings, which offer a longer detection window of up to 90 days, conducted under supervision to minimize tampering risks. However, for recent usage within 5 days, urine tests remain more effective.

What it is, How it works

Hair analysis is now regarded as a potent method for identifying drug and alcohol consumption. Hair offers an extended timeline by capturing markers in the strands of growing hair. Collected near the scalp, hair can reveal alcohol and drug presence for up to roughly 3 months. It's straightforward to collect, somewhat resistant to tampering, and easy to transport.

A sample measuring 1.5 inches of roughly 200 hair strands (comparable to a #2 pencil) near the scalp provides 100mg, which is ideal for evaluation and validation. For EtG, additional tests, and/or those exceeding 10 panels, a specimen of 150mg is advised. We advise using a jeweler’s scale for weighing the sample. If scalp hair isn't available, an equivalent amount of body hair can be used. In discussing head hair, we mean scalp hair only, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The lab processing of drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial integration of a sample into a lab's system. This covers confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody.

Screening offers a preliminary check for drug abuse. Screening is a low-cost method to eliminate drug usage in most samples, but a positive screen requires confirmation for court validity. Samples that test potentially positive in Screening need a further confirmation.

If Screening indicates a presumptive positive, more hair is extracted from the initial sample for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration than other methods (like urine or oral fluid), making hair drug testing the most challenging method to perform.

Confirmation of positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The entire lab sequence from Accessioning to Confirmation is verified under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Benefits of hair drug analysis:

  • Extended detection length: Hair tests identify drug usage for as long as 90 days, while urine tests have a shorter timeframe.
  • Challenging to falsify: It is exceedingly difficult to deceive a hair drug test, ensuring more reliable results.
  • Provides usage history: It illustrates a pattern of drug consumption over a period rather than just recent use.

Drawbacks:

  • Inability to detect recent usage: It requires 5-7 days for drugs to register in hair.
  • Expense: Hair drug tests tend to cost more than other testing techniques.
  • Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Often termed "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
Yes. If the donor's head hair is too short or unavailable, body hair may be collected as an alternative. The collector will document the source of the sample. This allows testing even for individuals with recently cut or shaved head hair.
Yes. Hair drug testing is commonly used in court, probation, custody, and compliance matters because the collection process follows a documented chain of custody and the analysis is performed by a certified laboratory.
