Hair testing is now considered an effective method for identifying alcohol and drug consumption. Hair retains biomarkers within the fibers of the growing strand, reflecting a long-term history of substance use. A sample taken near the scalp can indicate drug or alcohol presence for up to around 90 days. It's straightforward to collect, hard to tamper with, and simple to transport.
An optimal sample should be 1.5 inches of about 200 strands of hair (roughly equivalent to the width of a #2 pencil) nearest to the scalp, yielding 100mg of hair for testing and verification. For EtG, additional tests, or panels beyond 10, 150mg is advisable. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair can't be sourced, a comparable amount of body hair is acceptable. Unless specified, "head hair" means scalp hair while "body hair" encompasses all other hair types (such as facial or axillary hair).
Process Overview
The four principal phases in processing drug tests in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the assimilation of a sample into the lab's system. This includes ensuring the sample was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data recording not covered by an electronic chain of custody system.
Screening provides a preliminary quick assessment for drug usage. Though cost-efficient for eliminating drug use in most samples, a positive Screening outcome must be verified to hold up in legal settings. Any samples with preliminary positive results in Screening necessitate additional confirmation.
Should a sample test presumptively positive during Screening, more hair is extracted from the original sample for Extraction. Here, drugs are removed from hair at much lesser concentrations in contrast to alternative methods (like urine or oral fluid), accounting for the complexity of hair drug screening.
Positive screening confirmations are performed using GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples are cleaned pre-confirmation as needed. The entire lab procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair category and the accreditation to ISO / IEC 17025 standards.

Note: Although often known as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
