Hair tests are now perceived as a robust method for identifying drug and alcohol consumption. By capturing biomarkers within the strands of growing hair, hair offers a lengthy overview of alcohol and drug intake. When taken near the scalp, it can reveal substance use within an approximate 3-month timeframe. Hair collection is straightforward, somewhat resistant to tampering, and simple to transport.
A sample measuring 1.5 inches and comprising roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp yields 100mg, which is ideal for both screening and confirmation. For EtG add-ons and/or analyses exceeding 10 panels, a specimen of 150mg is advisable. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair isn’t available, an equivalent amount of body hair can be gathered. When referencing head hair, we're specifically talking about scalp hair. 'Body hair' encompasses all other hair types (facial, axillary, etc.).
Process Overview
The process of producing lab results from a drug test comprises four major stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the lab system. This involves confirming the sample was properly sealed and dispatched, assigning a LAN (Laboratory Accessioning Number) at random, and completing any other data input absent from an electronic chain of custody.
Screening provides an initial rapid assessment for drug use. While it is a cost-effective method for eliminating drug use in most samples, a positive screening requires confirmation to be court-admissible. Samples with presumptive positive results in Screening demand a secondary verification.
If a sample shows a presumptive positive during Screening, additional hair is removed from the initial sample for Extraction. During Extraction, drugs are separated from hair at significantly lower concentrations than with other techniques (e.g., urine or oral fluid), establishing hair drug testing as the most complex method to conduct.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with a presumptive positive status are cleansed before confirmation if necessary. From Accessioning through Confirmation, the entire process is evaluated under the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation standards.
