Hair tests have become recognized as an effective mechanism for identifying the consumption of drugs and alcohol. Hair captures a prolonged record of alcohol and drug intake by embedding markers within the fibers of the hair as it grows. When clipped near the scalp, it can offer roughly a 90-day detection period for both alcohol and drugs. Collecting hair is straightforward, relatively hard to tamper with, and easy to transport.
A 1.5-inch sample comprising about 200 hairs (roughly the width of a #2 pencil) closest to the scalp results in 100mg of hair, which is the recommended amount for both screening and confirmation. For EtG, add-ons, and/or analysis exceeding 10 panels, a quantity of 150mg is preferable. We advise using a jeweler's scale for weighing the sample. In cases where scalp hair isn't available, an equivalent quantity of body hair can be used. References to head hair mean scalp hair only. Body hair includes all other hair types (like facial or axillary).
Process Overview
The key phases in the laboratory handling of a drug test sample include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the sample's initial input into the laboratory's system. This process confirms the sample was appropriately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry not managed by an electronic chain of custody protocol.
Screening is the first swift evaluation for drug presence. Screening is cost-efficient for negating drug use in most samples; however, a clear result on this step is essential for it to be valid in a legal context. Any sample that appears positive during Screening mandates further confirmation.
Should a sample show a positive indication in Screening, additional hair is taken from the initial collection and readied for Extraction. Here, drugs are drawn from hair at a considerably lower concentration than other methods (such as urine or oral fluid), underlining why hair drug testing is notably challenging.
A positive screen confirmation is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples suspected to be positive are cleansed before confirmation if required. The complete laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.
