Hair testing is regarded as a robust method for identifying drug and alcohol consumption. Hair offers an extensive history of substance use by capturing biomarkers within the fibers of the developing hair strand. When sourced near the scalp, hair can provide an approximate 3-month period of detection for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil) from near the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of the specimen is advised. We suggest utilizing a jeweler’s scale for weighing the specimen. If scalp hair is absent, a similar amount of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair denotes all other hair types, such as facial or axillary hair.
Overview of the Process
The key stages in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the sample's preliminary processing into a lab's system. This step verifies that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any data entry missing from an electronic chain of custody system.
Screening is an initial basic check for drug presence. While cost-effective for excluding drug use in most samples, a positive screening requires confirmation for court admissibility. Presumptively positive samples from Screening necessitate a subsequent confirmation.
For samples that are presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing exceptionally challenging to execute.
Any confirmed positive results undergo verification using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as needed. The laboratory's entire operation from Accessioning to Confirmation is assessed following both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Drawbacks:
Note: Though frequently called "hair follicle tests," the test evaluates the hair strand and not the follicle beneath the scalp.
