Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has emerged as a powerful method for identifying alcohol and drug consumption. Hair provides an extended history of substance use by capturing biomarkers within the fibers of the hair strand as it grows. When taken near the scalp, a hair sample can offer a detection period of up to around 90 days for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to send.
A sample size of 1.5 inches with approximately 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, which is the ideal amount for testing and verification. For EtG, additional tests, and/or tests over 10 panels, 150mg of hair is advised. We suggest using a jeweler's scale for measurement. If scalp hair can't be collected, an equivalent quantity of body hair may be used. "Head hair" means scalp hair only, while "body hair" includes other types like facial or armpit hair.
Process Overview
The main steps in processing a drug test sample in a lab are Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is initially processed into the lab's system, which includes confirming the proper sealing and shipping of the sample, providing a random LAN (Lab Accessioning Number), and finishing any extra data entry not covered by an electronic chain of custody.
Screening is a quick initial check for substances. While it offers a cost-effective way to rule out drug use for most samples, a confirmed positive screen is required for it to be legally valid. Any samples that test positive in the initial Screening must undergo further Confirmation.
Should a sample test positive in Screening, additional hair is taken from the original sample for the Extraction phase. During this phase, drugs are isolated from the hair at much lower concentrations than with other testing methods (such as urine or oral fluid), making hair drug testing particularly challenging.
Confirmation of initial positive results is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before final confirmation if necessary. The entire laboratory process from Accessioning through Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.

Limitations:
Note: The test often misnamed "hair follicle test" actually analyzes the hair strand rather than the follicle beneath the scalp.
