Hair testing has gained recognition as an effective method for detecting drug and alcohol consumption. Hair serves as a record of alcohol and drug presence by encapsulating biomarkers in the strands of hair as it grows. When taken near the scalp, hair can offer up to a 3-month detection time frame for substances. Collecting hair is straightforward, fraud attempts are more challenging, and it is easy to transport.
A 1.5-inch piece comprised of about 200 hair strands (comparable in size to a #2 pencil) near the scalp will yield 100mg of hair, which is the ideal amount for screening and confirmation. For EtG, addons, and/or tests exceeding 10 panels, a 150mg sample is advisable. It's suggested to use a jeweler’s scale for weighing the sample. If scalp hair isn't available, an equal amount of body hair can be used. In the context of head hair, we mean scalp hair specifically, whereas body hair encompasses other types (face, axilla, etc.).
Process Overview
The four primary stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample is integrated into a lab's workflow. This process ensures the sample was properly sealed and sent, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.
Screening is a primary, swift evaluation for drugs of abuse. Though this method is cost-efficient in eliminating drug use in most samples, a positive result must undergo confirmation to be valid in legal situations. All samples with a presumptive positive in Screening necessitate additional confirmation.
If Screening indicates a presumptive positive, additional hair from the initial batch is readied for Extraction. During Extraction, drugs are isolated from hair at concentrations significantly lower than those in other techniques (e.g., urine or oral fluids), highlighting the complexity of hair drug screening.
Positive results from Screening are confirmed via GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo pre-confirmation washing as necessary. Both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation ensure oversight of the process from Accessioning to Confirmation.
