Urine| Hair Follicle | Oral Fluid | Blood | ETG
The use of hair testing has been widely recognized as an effective method for identifying drug and alcohol use. Hair captures long-term substance history by embedding biomarkers within the fibers as it grows. When gathered near the scalp, a hair sample can provide an approximate 3-month timeframe for alcohol and drug detection. Hair collection is straightforward, generally tamper-resistant, and convenient for transport.
A 1.5-inch segment consisting of about 200 hairs (similar to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for screening and confirmation tests. For EtG, additional tests, and/or those exceeding 10 panels, a 150mg specimen is advisable. Utilizing a jeweler’s scale for weighing the specimen is suggested. In cases where scalp hair is unavailable, a comparable amount of body hair can be utilized. Note that head hair specifically refers to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
There are four primary stages in the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially processing a sample within a laboratory’s system. This process includes ensuring the sample’s proper seal and shipment, assigning a random Laboratory Accessioning Number (LAN), and completing any data entry not covered by an electronic chain of custody system.
Screening includes a preliminary swift drug abuse check. Although Screening is an economical method for ruling out drug usage in most samples, confirmation is needed for any positive screen to be court-admissible. Presumptive positive samples require secondary confirmation.
In cases of presumptive positivity during Screening, more hair is extracted from the original specimen and readied for Extraction. During this stage, drugs are extracted from hair in significantly lower concentrations than with other methods (e.g., urine or oral fluid), illustrating why hair drug screening is amongst the most complex to conduct.
A positive screening result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation when necessary. The entire lab process from Accessioning through Confirmation is reviewed in compliance with both the College of American Pathologists (CAP) Hair designation and ISO/IEC 17025 accreditation standards.

Note: Commonly called "hair follicle tests", these tests analyze the hair strand itself and not the follicle beneath the scalp.
