Hair testing is regarded as an effective method for identifying alcohol and drug consumption. It offers a prolonged history by capturing biomarkers within the strands of growing hair. Hair collected near the scalp can reveal a detection span for alcohol and drugs of up to about 90 days. It's uncomplicated to collect, somewhat challenging to tamper with, and straightforward to transport.
A hair sample measuring 1.5 inches and comprising 200 strands near the scalp can produce 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a sample of 150mg is advisable. Using a jeweler's scale is recommended for weighing the sample. If scalp hair isn't present, an equivalent amount of body hair is acceptable. "Head hair" specifically refers to scalp hair. "Body hair" encompasses all other types, such as facial and axillary hair.
Process Overview
The primary steps in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of logging the sample into the lab's system, including ensuring the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing extra data entry if the electronic chain of custody system doesn't provide it.
Screening is a rapid assessment for drugs of abuse. Although it is a cost-effective method to dismiss drug use for most samples, a confirmed positive screen is required to be valid in court. Samples with a presumed positive in Screening need confirmation.
When a sample appears positive during Screening, additional hair is selected from the original specimen and prepared for Extraction. In this stage, drugs are extracted from hair in much lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening the most intricate method to execute.
Confirmation of any positive screen is done through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation as needed. The entire process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and certified to ISO / IEC 17025 standards.

Note: Although often called "hair follicle tests", it is the hair strand itself that is analyzed, not the hair follicle under the scalp.
