Hair analysis is now regarded as an effective method for identifying the use of substances. Hair can capture a longer timeline of alcohol and drug use by holding biomarkers within its strands. When taken near the scalp, hair can show evidence of substance use for up to 90 days. It's easy to gather, tough to tamper with, and straightforward to mail.
A 1.5-inch portion of around 200 hair strands, comparable to the size of a #2 pencil, near the scalp provides 100mg, the preferred amount for exams and validation. For tests like EtG, extensions, and those exceeding 10 panels, 150mg is suggested. Using a jeweler’s scale to weigh the sample is advisable. If scalp hair isn't present, a comparable amount of body hair is an alternative. "Head hair" denotes scalp hair specifically, while "body hair" includes other types (such as facial or underarm hair).
Process Overview
Key stages in lab analysis of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary intake of a specimen into the lab’s system. This step ensures that the sample is securely sealed and correctly sent, a random LAN (Laboratory Accessioning Number) is generated, and fills any data entry gaps not covered by an electronic chain of custody method.
Screening is a preliminary evaluation for drug traces. Though a cost-effective method to exclude drug presence in most samples, a positive screen necessitates validation for legal acceptance. Any samples tentatively positive in Screening require a subsequent confirmation check.
In cases where Screening indicates a presumptive positive result, additional hair is taken from the original sample for Extraction. This is where drugs are isolated from hair at considerably lower levels than seen in other tests (e.g., urine or oral fluid), underscoring why hair drug testing is notably complex.
Verification of any positive screening is completed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positives undergo cleansing as needed. The complete laboratory sequence from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 norms.
