Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. This approach offers an extensive history of substance use due to the capture of biomarkers within the fibers of the hair as it grows. When samples are taken near the scalp, they can reveal substance presence over a period of up to three months. The method of collection is straightforward, challenging to tamper with, and convenient for transportation.
A hair sample measuring 1.5 inches and consisting of around 200 strands, roughly equivalent to the thickness of a #2 pencil, yields 100mg of hair, optimal for both screening and confirmatory procedures. For tests involving EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advised. It's best to assess the sample weight using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair can be obtained. Here, "head hair" specifically denotes scalp hair, whereas "body hair" encompasses all other hair types such as facial and axillary hair.
Process Overview
The primary stages in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing into the lab's system. This step verifies that the sample is correctly sealed and delivered, assigns a random Laboratory Accessioning Number (LAN), and completes any necessary data entries not covered by an electronic custody system.
Screening serves as an initial evaluation for substance abuse. While this step is an economical method to discount drug use in most samples, a positive screen requires confirmation to be considered valid in legal contexts. Any presumptively positive Screening samples necessitate secondary confirmation.
If a sample is flagged as presumptively positive during Screening, additional hair is extracted and prepared for the Extraction phase. Here, drugs are isolated from hair in concentrations significantly lower than other methods, such as urine or oral fluid testing, making hair analysis particularly challenging to perform.
Confirmation of any positive Screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS technology. Presumptive positive samples undergo cleansing before confirmation if needed. The complete lab process from Accessioning through Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Though commonly called "hair follicle tests," the actual examination is conducted on the hair strand, not the follicle beneath the scalp.
