Lately, the practice of executing drug screenings more often involves using a hair follicle test. Numerous employers, judicial bodies, and specialists in Substance Abuse are opting for hair drug tests rather than conventional urine tests. Hair follicle tests are preferred by employers enforcing strict no-drug-usage rules, courts, and individuals undergoing probation. The primary advantage is that it can identify drug use for an extended period, up to 90 days, through an observed process that is nearly foolproof.

Hair analysis is now widely regarded as a robust method for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers as it grows, thus offering a long-term record of substance use. When sourced near the scalp, the detection period for substances like alcohol can extend up to three months. Hair collection is straightforward, challenging to tamper with, and simple for transportation.
A sample size of 1.5 inches, containing roughly 200 strands (comparable to the width of a #2 pencil), which is near the scalp, yields around 100mg of hair—ideal for testing and confirmation. For additional testing such as EtG or panels beyond ten, 150mg is advisable. We suggest using a jeweler’s scale for accurate measurement. If scalp hair is absent, a similar quantity of body hair should be used. Here, "head hair" specifically means scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The lab processing of drug test outcomes involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample first gets processed into the lab’s system. This phase includes checking the sample’s sealing and shipping integrity, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing information not captured by an electronic chain of custody system.
Screening acts as an initial, brisk assessment for substance abuse. As a cost-efficient approach, it clears most samples of drug use; however, confirmed results are necessary for legal proceedings. Samples marked as presumptively positive in Screening require further confirmation.
Should Screening suggest a positive, additional hair from the initial sample undergoes Extraction. Here, drugs are isolated from hair at lower concentrations than in alternate methods like urine or saliva, establishing hair drug screening as the most complex methodology.
Confirmation for any positive results follows via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before this step if needed. The comprehensive lab procedure, from Accessioning through Confirmation, complies with the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
