Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis is recognized as an effective method for detecting substance and alcohol consumption. Hair retains a long-term record of these substances by embedding biomarkers within the strands as they grow. When sampled near the scalp, hair can reveal a detection timeframe of nearly 90 days for alcohol and various drugs. Collecting hair is straightforward, resisting tampering, and convenient for transport.
A sample of around 1.5 inches consisting of roughly 200 hair strands (similar in width to a #2 pencil) taken from the scalp will yield approximately 100mg of hair, which is optimal for testing and verification. For testing involving EtG, additional panels, or more than 10 panels, a specimen weighing 150mg is advisable. It's suggested to measure the specimen using a jeweler’s scale. Should scalp hair be unobtainable, an equivalent amount of body hair may be gathered. The term 'head hair' specifies scalp hair exclusively, whereas 'body hair' covers all other hair types (facial, axillary, etc.).
Process Overview
The sequential steps in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to initial sample integration into a lab’s system. This process verifies proper sealing and shipping, generates a random Laboratory Accessioning Number (LAN), and completes additional data entry absent from an electronic chain of custody system.
Screening provides a preliminary examination for drug presence. Although cost-effective for negating drug use in most samples, a positive screening must be verified to be legally acceptable. Any presumptively positive samples require further confirmation.
A sample testing presumptively positive in Screening enters Extraction, where additional hair is retrieved from the initial sample and prepared. Drugs are extracted from hair at a concentration much lower than other methods (e.g., urine, oral fluid), making hair drug testing the most challenging methodology.
Confirmation of a positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives undergo washing before confirmation as needed. The entire lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and meets the ISO / IEC 17025 standards.

Note: While commonly termed "hair follicle tests", the focus is actually on analyzing the hair strand, not the scalp hair follicle.
