Whether you require a hair drug or alcohol test, we specialize in hair analysis and provide testing facilities in all major cities nationwide. A hair length of 1.5 to 2 inches on the head or body is typically needed. Hair testing can be conducted for drugs, alcohol/ETG, or other personalized options.
In recent times, hair follicle drug testing has become increasingly prevalent. Various organizations, judicial bodies, and substance abuse professionals now prefer this method over traditional urine tests. Employers with zero-tolerance policies, courts, and probationers rely on hair tests due to their extended detection period of up to 90 days, observed collection process, and high resistance to tampering. However, for detecting recent drug use within the last 5 days, urine tests remain most effective.

Utilizing hair tests has emerged as an effective method for identifying alcohol and drug consumption. Hair offers an extended history of substance use by embedding biomarkers within the strands as the hair grows. When gathered near the scalp, hair can indicate substance consumption over a period of up to three months. It is straightforward to collect, relatively hard to tamper with, and convenient to ship.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (around the mass of a #2 pencil), will yield 100mg, which is the peak sample for analysis and validation. For EtG, supplemental tests, or those exceeding 10 panels, 150mg is advised. It's suggested to measure the hair on a jeweler’s scale. Should scalp hair be absent, an equivalent amount of body hair is acceptable. Head hair specifically refers to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The drug testing lab procedure consists of four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the initial entry of a specimen into a lab's database. It verifies proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes data entry not automatically recorded by an electronic chain of custody.
Screening performs an initial and swift assessment for drug presence. While screening serves as a cost-effective technique to dismiss drug use in most specimens, a positive result must be confirmed for legal validity. Specimens showing presumptive positivity in Screening necessitate further confirmation.
When a specimen shows presumptive positivity during Screening, additional hair is extracted from the original sample for preparation in the Extraction stage. In this phase, drug compounds are derived from hair at lower concentrations compared to other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmatory analysis of any positive screen utilizes GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples indicated as presumptively positive undergo washing before confirmation where necessary. The comprehensive lab procedure, from Accessioning through Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
