Accredited Drug Testing offers thorough hair follicle drug testing services in Winters, California. If you're in need of a hair drug or alcohol test, Accredited Drug Testing is an expert in hair testing and provides services in cities across the Nation. Typically, hair from the crown or body of 1.5 to 2 inches in length can be used. Hair tests are available to assess for drugs, alcohol/ETG, and other tailored testing needs.

In recent times, drug testing methods have increasingly adopted the hair follicle test. Plenty of employers, courts, and Substance Abuse experts now favor hair drug tests over traditional urine tests. Employers with strict no-drug policies, judicial systems, and individuals on probation find hair follicle testing beneficial. Its main advantage is an extended drug detection window of up to 90 days, collected under observation, and it's almost impossible to tamper with. Nonetheless, for detecting recent drug use within the past 5 days, urine tests remain the most precise choice.

What it is, How it works

Hair analysis is now recognized as an effective method for uncovering drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug intake by securing biomarkers within the hair's developing fibers. When procured near the scalp, hair can reveal a detection span of up to roughly three months for alcohol and drugs. Hair is straightforward to obtain, challenging to tamper with, and simple to transport.

A 1.5-inch segment of about 200 hairs (resembling the size of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal sample for both testing and verification. For EtG, supplementary analyses, and tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample on a jeweler's scale. If scalp hair is unavailable, a matching amount of body hair can be used. By head hair, we mean scalp hair specifically. Body hair encompasses all other hair forms (face, underarm, etc.).

Process Overview

The process in the lab for deriving a drug test result comprises Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial step of entering a sample into the lab's system. This step confirms that the sample was correctly sealed and dispatched, assigns it a random LAN (Laboratory Accessioning Number), and completes any extra data entry absent from an electronic chain of custody system.

Screening involves an initial, rapid assessment for drugs of abuse. Although Screening is a cost-efficient method to exclude drug use on the majority of samples, a positive screening must be validated for court acceptance. Any samples testing presumptively positive during Screening require follow-up confirmation.

If a sample appears presumptively positive during the Screening phase, additional hair is pulled from the original sample and readied for Extraction. In this phase, drugs are severed from hair at significantly lower concentrations compared to other methodologies (e.g., urine or saliva), which is why hair drug testing is among the most complex methodologies to execute.

Confirmation of any positive screen result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation if necessary. The entire lab procedure from Accessioning through Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection span: Hair drug tests can track drug usage up to 90 days, contrasting with urine tests that have shorter detection spans.
  • Hard to deceive: It's very challenging to deceive a hair drug test, which enhances result accuracy.
  • Offers historical insight: It provides a usage pattern of drugs over time, not merely immediate use.

Limitations:

  • Incapable of recent detection: It takes around 5-7 days for drugs to be traceable in hair.
  • Expense: Hair drug testing is generally pricier than other drug testing alternatives.
  • Result variations: Elements like hair color and individual hair growth differences can influence the drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests," the analysis is 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.

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.
