Hair testing is widely regarded as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance usage by entrapping biomarkers within the strands as they grow. When the hair is sampled near the scalp, it can reflect up to a roughly 3-month timeframe for substance detection. The collection of hair is straightforward, offers resistance to tampering, and is easily transported.
A sample measuring 1.5 inches with approximately 200 strands (similar to the thickness of a #2 pencil) nearest the scalp will yield 100mg, which is the optimal quantity for both screening and validation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advisable. It's best to measure the sample using a jeweler's scale. In the absence of scalp hair, a comparable quantity of body hair can be used. When mentioning head hair, it exclusively denotes scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves inserting a sample into the lab's system. This stage verifies the sample's proper sealing and shipment, assigns it a random LAN (Laboratory Accessioning Number), and fulfills any supplementary data entry missing from an electronic chain of custody.
Screening involves an initial quick assessment for prohibited drugs. Screening serves as a budget-friendly means to exclude drug usage in most samples. However, a positive screen must be confirmed for court admissibility. Any samples showing presumptive positives in Screening require further confirmation.
Should a sample show presumptive positive results in the Screening phase, additional hair from the original specimen undergoes Extraction preparation. In this step, drug substances are extracted from hair at a significantly lower concentration than other approaches (such as urine or oral fluid), making hair drug screening a challenging technique.
Confirmation of any positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positives undergo washing as necessary. The lab procedures from Accessioning to Confirmation are examined under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
