Hair analysis has emerged as an effective method for identifying drug and alcohol use. By embedding biomarkers within the fibers of the developing hair strand, hair offers an extended timeline of substance history. Obtained near the scalp, hair samples can reveal alcohol and drug use over roughly a three-month duration. Hair sampling is straightforward, relatively hard to tamper with, and easily transportable.
A sample measuring 1.5 inches with about 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp produces 100mg of hair, the preferred quantity for both screening and confirmation. For EtG, supplemental testing, and/or panels exceeding 10, a 150mg sample is advisable. We suggest measuring the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent body hair sample can be collected. 'Head hair' specifically refers to scalp hair, whereas 'body hair' encompasses all other hair types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result can be divided into four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a sample within a lab's system. This step includes confirming the proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not covered by an electronic chain of custody system.
Screening signifies an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient method to rule out drug use in most samples, any positive results must be confirmed to be legally accepted. Samples deemed presumptively positive in Screening necessitate a subsequent confirmation test.
When a sample tests presumptively positive during Screening, additional hair is extracted from the primary specimen for the Extraction phase. In this step, compounds are isolated from hair at concentrations significantly lower than those found in other methods (e.g., urine or oral fluid), illustrating why hair drug screening is particularly complex.
Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned prior to confirmation if required. The laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Note: Although often called "hair follicle tests," the actual examination focuses on the hair strand rather than the follicle beneath the scalp.

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.
