Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. It offers an extensive timeline for substance use by capturing biomarkers within the hair's growing fibers. Samples gathered near the scalp can reveal drug and alcohol traces for up to about 90 days. The collection process is straightforward, tampering is relatively challenging, and transportation is hassle-free.
A sample size of 1.5 inches, consisting of roughly 200 hair strands (approximately the diameter of a #2 pencil) near the scalp offers 100mg, which is optimal for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen weight of 150mg is suggested. Utilizing a jeweler’s scale for measuring the specimen is advised. If scalp hair is absent, a similar quantity of body hair can be used. The term "head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The comprehensive steps in laboratory drug testing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails incorporating a sample into the lab's system. This procedure involves ensuring the sample remains sealed and is shipped correctly, assigning a random Laboratory Accessioning Number (LAN), and filling in any additional data not included in the electronic chain of custody.
Screening acts as a preliminary examination for abused substances. Although Screening is a cost-efficient approach to exclude drug use in most samples, a positive result demands confirmation to be legally viable. Those samples with presumptive positive results require subsequent confirmation.
Presumptively positive samples necessitate more hair from the original sample for Preparation for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which makes hair drug screening exceptionally challenging.
Verification of positive screening outcomes is conducted using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with false positives are washed pre-confirmation if required. The entire lab procedure from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditations.
