Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair offers an extended history of substances by embedding biomarkers within the strands as they grow. When taken near the scalp, hair can show alcohol and drug use up to roughly a three-month period. Collecting hair is straightforward, challenging to tamper with, and simple to mail.
A sample measuring 1.5 inches, composed of approximately 200 strands (similar to a #2 pencil) nearest the scalp, yields 100mg of hair, which is optimal for analysis. For EtG, additional tests, or panels above 10, a specimen of 150mg is advised. A jeweler’s scale is recommended for weighing. If scalp hair is not available, an equivalent amount of body hair might be used. The term head hair specifically refers to scalp hair. Body hair includes all other types, such as facial and axillary hair.
Process Overview
The drug test laboratory process consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial sample registration in a lab’s system. This process ensures the sample is properly sealed and shipped, assigns a Laboratory Accessioning Number (LAN) randomly, and completes any extra data entry not included in an electronic chain of custody.
Screening provides a preliminary assessment for drug presence. Although Screening is an affordable technique to eliminate drug usage in most specimens, a positive result must undergo confirmation for court admissibility. Samples showing presumptive positivity in Screening necessitate additional validation.
Once a sample shows presumptive positivity during Screening, more hair is prepared from the original specimen for Extraction. During this stage, drugs are extracted from hair at a much lower level than methods such as urine or oral fluid, making hair drug screening the most intricate method to execute.
Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples undergo washing before confirmation if needed. Each step, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the standards accredited by ISO / IEC 17025.
