Over time, hair testing has established itself as an effective means for identifying drug and alcohol consumption. Hair serves as a chronicling medium for the use of alcohol and drugs, encapsulating biomarkers within the strands as they grow. If taken near the scalp, hair offers a detection timeframe of up to roughly three months for both alcohol and various drugs. It's easy to gather, challenging to tamper with, and convenient to forward.
An approximated 1.5-inch segment of nearly 200 hair strands (akin to the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation. For extended tests such as EtG or panels beyond ten, a 150mg sample is advisable. We suggest using a jeweler's scale to weigh the sample accurately. In the absence of scalp hair, a similar quantity of body hair can be used. When we speak of head hair, we exclusively refer to scalp hair. Body hair encompasses all other hair types like facial or axillary hair.
Process Overview
The process for processing a drug test result in a lab comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially introduced into the laboratory's system, which involves making sure it was sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and executing any additional data entry lacking an electronic chain of custody system.
Screening involves performing a quick preliminary analysis for drugs. While Screening is cost-efficient to eliminate drug use in the majority of samples, a positive result from Screening necessitates verification to be considered valid in legal contexts. Any samples flagged as presumptively positive in Screening require further confirmation.
If a sample indicates a presumptive positive in the Screening phase, more hair is taken from the beginning specimen and readied for Extraction. In this phase, drugs are isolated from hair at a lower concentration compared to other methods (such as urine or oral fluid), which makes hair drug testing a challenging procedure to execute.
Confirmation of positive screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples indicating presumptive positivity are subject to a cleansing process as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair category and the ISO / IEC 17025 standards of accreditation.
