Hair testing has emerged as a robust method for detecting drug and alcohol consumption. Hair strands archive a long-term record of alcohol and drug presence by capturing biomarkers within their growing fibers. When taken near the scalp, hair tests offer roughly a 3-month detection span for alcohol and drugs. Hair collection is straightforward, difficult to tamper with, and easy to transport.
A 1.5-inch section consisting of around 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg, which is ideal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a collection of 150mg is suggested. Utilize a jeweler’s scale for specimen weighing. If scalp hair cannot be used, an equivalent amount of body hair should be obtained. Reference to head hair implies scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The four fundamental stages in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially integrating a sample into the lab’s system. This process includes ensuring the sample’s seal and shipment were correct, assigning a random LAN (Laboratory Accessioning Number), and performing any needed data entry not covered by an electronic chain of custody.
Screening provides a preliminary test for drug presence. While it is an economical way to eliminae drug use in most samples, a positive result needs confirmation for court acceptability. Presumptive positives in Screening require further confirmation.
When a sample tests presumptively positive at Screening, additional hair is used from the original sample for Extraction. Here, drugs are pulled from hair at much lower concentrations than other methods (e.g., urine or oral fluid), explaining why hair drug testing is more challenging.
GC/MS, GC/MS/MS, or LC/MS/MS are used to confirm a positive screen. All presumptive positives undergo washing before confirmation as necessary. The laboratory process, from Accessioning through Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly called "hair follicle tests", the analysis targets the hair strand instead of the follicle beneath the scalp.
Superior Detection: Hair follicle testing in Sonoma, CA trumps traditional urine tests in several ways. Its superior accuracy ensures that even infrequent drug use doesn't go undetected.
