Typically, hair from the head's crown or body, measuring 1.5 to 2 inches, is required, enabling us to test for various substances, including drugs, alcohol/ETG, or other customized testing needs.
Recently, hair follicle drug tests have become more prevalent as a testing method. It's favored by numerous employers, legal systems, and substance abuse experts as an alternative to urine tests. Notably, employers with stringent no-drug policies, courts, and probation programs prefer this test. Hair tests are credited for their extensive detection timeline, reaching up to 90 days, conducted under supervision, and are extremely difficult to alter. Nonetheless, for detecting recent drug use (within 5 days), urine tests still reign as the most precise.

Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol use. Hair retains a historical record of alcohol and drug consumption by capturing biomarkers within the hair strand fibers as they grow. When hair is gathered from near the scalp, it can reveal up to a three-month detection period for alcohol and drugs. The collection of hair is straightforward, relatively hard to alter, and convenient to transport.
A 1.5-inch section consisting of around 200 hair strands (roughly the girth of a #2 pencil) taken nearest the scalp yields 100mg of hair, which is the ideal quantity for both screening and confirmation. Additional tests like EtG or those exceeding 10 panels require 150mg of hair. It's advised to measure the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be used. The term head hair specifically denotes scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory's system. This process includes ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not covered by an electronic chain of custody system.
Screening provides a preliminary rapid evaluation for the presence of drugs. Although screening is an economical way to exclude drug usage for most samples, a positive screening result must be validated to be used in legal proceedings. Samples identified as presumptively positive during screening require further confirmation.
When a specimen tests presumptively positive during Screening, more hair is extracted from the primary sample for the Extraction stage. In this phase, drugs are retrieved from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging technique.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing as necessary before confirmation. The entire process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests", the analysis examines the hair strand itself and not the follicle beneath the scalp
