Hair testing has emerged as a potent instrument for identifying drug and alcohol usage. Hair offers an extended history of substances by encapsulating biomarkers within the fibers of the hair as it grows. When clipped close to the scalp, hair can indicate substance usage over a nearly 3-month period. Hair collection is straightforward, tough to tamper with, and easy to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the perfect sample size for screening and confirmation. For EtG, supplemental add-ons, and/or examinations exceeding 10 panels, a 150mg sample is advisable. We suggest measuring the specimen using a jeweler's scale. If scalp hair isn't available, a comparable amount of body hair can be collected. "Head hair" specifically refers to scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
There are four pivotal stages in laboratory handling of a drug test sample: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the primary handling of a specimen within a lab's framework. This entails confirming that the specimen was properly sealed and sent, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain-of-custody protocol.
Screening offers an initial rapid assessment for substances of abuse. Though it serves as a cost-effective approach to eliminate drug use in most cases, a positive screening result requires validation to be accepted in legal settings. Any samples presumed positive in Screening necessitate secondary verification.
If Screening suggests a sample is positive, additional hair is extracted from the initial sample and readied for Extraction. This phase involves isolating drugs from hair at far lower concentrations compared to alternative methods (e.g., urine or saliva), which makes hair drug testing the most challenging to execute.
Verification of any presumptively positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples assumed positive are cleansed before verification as required. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests," the assessment itself scrutinizes the hair strand, not the follicle beneath the scalp
