Should you require a hair drug or alcohol screening, our expertise in hair analysis is unparalleled, and with nationwide testing facilities, hair testing is accessible from any city. Typically, 1.5 to 2 inches of hair from the scalp or body can be examined. These tests can identify drugs, alcohol/ETG, or be tailored to specific requirements.
In recent times, there has been a shift towards utilizing hair follicle drug tests for substance detection. A multitude of employers, judicial bodies, and addiction specialists now favor hair tests over traditional urine concentrations. These tests cater to organizations with strict drug-free mandates, legal systems, and those overseeing probationers. The standout advantage of hair follicle testing is its extended detection timeline which can reveal drug use up to 90 days prior, overseen in a monitored setting with minimal risk of manipulation. Conversely, urine tests remain the benchmark for detecting drug consumption within the immediate past five days.

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair retains a lengthy record of alcohol and other substances by embedding biomarkers within the fibers of the growing hair strand. When obtained near the scalp, hair can reveal up to a 3-month detection period for alcohol and other substances. Hair is easy to collect, challenging to tamper with, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to the size of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal sample for screening and validation. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the sample is recommended. It's advisable to weigh the sample on a jeweler’s scale. If scalp hair is not available, a similar amount of body hair may be taken. When referring to head hair, we mean scalp hair specifically. Body hair pertains to all other hair types (facial, axillary, etc.).
Process Overview
The four primary steps in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample into a laboratory’s system. This process covers confirming the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry that the electronic chain of custody system does not provide.
Screening involves an initial quick check for drugs of abuse. While Screening is a cost-effective means to exclude drug usage for most samples, a positive screen must be validated to be court-admissible. Samples that are presumptively positive in Screening necessitate a secondary confirmation.
Should a sample be presumptively positive at the Screening phase, more hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are extracted from hair at a much lower concentration than through alternative methods (like urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening result is completed through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as needed. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
