In Grimes, California, Accredited Drug Testing offers thorough hair follicle drug testing services. If you need drug or alcohol testing via hair analysis, we have the expertise and numerous centers nationwide to serve your needs. Requiring 1.5 to 2 inches of hair from the scalp, or body hair, our hair tests can check for various drugs, alcohol/ETG, and offer tailored testing solutions.

The hair follicle drug test method has gained more traction in recent years for drug testing purposes. Employers, courts, and Substance Abuse professionals increasingly choose hair drug tests over traditional urine tests. Employers with zero-tolerance policies, as well as courts overseeing probation, benefit from the extended detection period of up to 90 days offered by hair tests, conducted under observation and highly resistant to tampering. However, for detecting recent drug use within 5 days, urine tests remain the most accurate.

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. The hair preserves a prolonged record of alcohol and drug intake by capturing biomarkers within the strands as they grow. When collected near the scalp, hair can offer up to a three-month detection period for alcohol and drugs. Hair is straightforward to collect, somewhat hard to tamper with, and convenient to transport.

A 1.5-inch portion of approximately 200 hair strands (around the diameter of a #2 pencil) closest to the scalp provides 100mg of hair, the optimal sample for both screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample on a jeweler’s scale. If scalp hair is absent, a similar amount of body hair can be obtained. Referring to head hair implies only the hair on the scalp, while body hair indicates all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result primarily involves the steps of Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary processing of a sample into a lab’s system. This entails confirming that the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not handled by an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of abuse. Although Screening is an economical way to exclude drug use in most samples, a positive screen must be validated to be permissible in legal settings. Any samples that are preliminarily positive in Screening necessitate secondary confirmation.

If a sample yields a presumptive positive in the Screening phase, more hair is extracted from the original specimen and readied for Extraction. At this stage, drugs are extracted from hair at a substantially lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to implement.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection window: Hair drug tests can ascertain drug usage for up to 90 days, unlike urine tests which have a shorter detection timeframe.
  • Difficult to deceive: It is quite challenging to cheat a hair drug test, resulting in more precise outcomes.
  • Offers historical insight: It can outline a pattern of drug use over a span of time, instead of just recent consumption.

Limitations:

  • Cannot recognize recent use: It requires roughly 5-7 days for drugs to become detectable in hair.
  • Expense: Hair drug tests are generally costlier than other drug testing methods.
  • Result variations: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly labeled as "hair follicle tests", the test examines the hair strand rather than the follicle beneath the scalp

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

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.
