Hair drug tests have gained prominence as an effective method for identifying drug and alcohol usage. Hair captures a historical timeline of alcohol and drug presence by preserving biomarkers within its fibers as it grows. By collecting hair near the scalp, it can offer around a 3-month detection timeframe for alcohol and drugs. The process of collecting hair is straightforward, challenging to adulterate, and simple to transport.
A sample measuring 1.5 inches with about 200 strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg—the perfect amount for initial and confirmatory testing. For add-ons like EtG or tests exceeding 10 panels, a 150mg sample is preferred. We advise weighing the specimen using a jeweler’s scale. If scalp hair is not an option, an equivalent amount of body hair might be gathered. Head hair specifically refers to scalp hair, while body hair encompasses other types (like facial or axillary hair).
Process Overview
The principal stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is introduced into the laboratory’s system. This involves confirming that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry not covered by an electronic chain of custody system.
Screening provides an initial rapid assessment for drugs of abuse. While Screening serves as an economical means to exclude drug use in most samples, any positive result must be confirmed for courtroom validity. Samples that appear positive during Screening require additional confirmation.
If a sample tests presumptively positive at the Screening stage, further hair is extracted from the original specimen for the Extraction phase. Here, drugs are isolated from hair in much lower concentrations than in other techniques (such as urine or saliva), making hair drug testing a particularly challenging method to perform.
Positive results from Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all presumptively positive samples are cleansed as necessary. The complete laboratory sequence from Accessioning to Confirmation adheres to reviews under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
