Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains biomarkers within its fiber strands, reflecting a prolonged history of alcohol and drug use. When collected near the scalp, it can reveal a detection timeline of up to three months for these substances. Hair collection is straightforward, resistant to tampering, and convenient for transport.
A 1.5-inch segment consisting of roughly 200 strands (similar to the size of a #2 pencil) nearest to the scalp can yield 100mg of hair, the preferred quantity for both screening and verification. For EtG add-ons or tests exceeding 10 panels, 150mg of hair is advisable. We suggest using a jeweler’s scale for precise measurement. If scalp hair isn't available, a similar quantity of body hair may be used. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
There are four essential stages in laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
The Accessioning phase involves initially integrating a sample into a laboratory's system. This step ensures the sample is properly sealed and delivered, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry that wasn't covered by an electronic chain of custody.
During Screening, a preliminary rapid check for drug abuse is conducted. Although Screening is a cost-efficient way to eliminate drug use in most cases, positive results must be confirmed to be valid in legal settings. Any samples that test presumptive positive in Screening necessitate further confirmation.
Should a sample be presumptively positive after Screening, additional hair is extracted from the initial sample for the next phase, Extraction. Here, drugs are extracted from hair at much lower levels compared to other testing methods (e.g., urine or oral fluid), making hair drug screening the most complex method to conduct.
Confirming any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, as needed. The complete lab procedure from Accessioning to Confirmation is conducted in compliance with the CAP (College of American Pathologists) Hair category and the accreditation against ISO/IEC 17025 standards.

Drawbacks:
Note: Although commonly termed "hair follicle tests," the analysis actually evaluates the hair strand rather than the scalp follicle.
