Hair analysis has increasingly become recognized as an effective method for identifying drug and alcohol consumption. The hair's structure captures biomarkers as the strand grows, offering an extended timeline for detecting substance use. When samples are taken near the scalp, the detection period for drugs and alcohol extends up to roughly 90 days. Hair sample collection is straightforward, relatively tamper-resistant, and effortless to transport.
A 1.5-inch segment containing roughly 200 hair strands (approximately the width of a #2 pencil) cut closest to the scalp yields 100mg, the preferred sample size for both preliminary tests and confirmatory analysis. To test for EtG, additional substances, or when requesting more than 10 panels, a 150mg sample is advisable. We advise using a jeweler’s scale for measuring the specimen's weight. Should scalp hair be absent, a similar quantity of body hair can be obtained. The term "head hair" refers solely to scalp hair, whereas "body hair" includes all other types (such as facial, axillary, etc.).
Process Overview
The laboratory drug testing process involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory’s system. This step ensures the sample was sealed and transported correctly, assigns it a random LAN (Laboratory Accessioning Number), and completes any required data entry absent in electronic chain of custody records.
Screening is designed for a rapid assessment of potential drug misuse. While cost-efficient for eliminating drug use in most samples, any positive Screening outcome necessitates a further confirmation to be legally valid. Samples showing a presumptive positive result in Screening must undergo secondary confirmation.
If Screening indicates a presumptive positive, additional hair from the initial specimen is prepared for Extraction. Drugs are then isolated from hair at significantly lower concentrations than other methods (such as urine or saliva testing), underscoring the complexity of hair drug analysis.
Confirmation of any positive results from Screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Samples that are presumptively positive undergo washing before confirmation as needed. The entire transition from Accessioning to Confirmation within the laboratory adheres to both the CAP (College of American Pathologists) Hair standard and ISO/IEC 17025 accreditation requirements.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the analysis actually examines the hair strand, not the follicle beneath the scalp.
