Hair analysis is recognized as an effective means for detecting substances such as drugs and alcohol. It offers a prolonged history by embedding biomarkers within the structure of the hair shaft. When cut near the scalp, it can reveal up to a 3-month retrospective window for alcohol and drug use. Collecting hair is straightforward, not easily tampered with, and convenient for transport.
A 1.5-inch lock comprising roughly 200 strands near the scalp yields 100mg of hair, an optimal amount for both screening and confirmation processes. For EtG, supplementary tests, or panels exceeding 10, a recommendation of 150mg is made. We advise using a jeweler’s scale to weigh the hair. If scalp hair is unavailable, an equivalent quantity of body hair should be used. The term 'head hair' pertains solely to scalp hair, whereas 'body hair' includes all other hair types (facial, axillary, etc.).
Process Overview
The key phases in lab analysis of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the sample’s initial processing into the lab’s system, ensuring the sample's seal and proper shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any pending data entry absent from an electronic chain of custody.
Screening is a preliminary and efficient method to detect drug presence but needs validation via confirmation for legal admissibility. Any samples that return a presumptive positive in Screening need secondary confirmation.
If Screening results suggest a positive, additional hair is taken from the original sample for Extraction. In this phase, drugs are separated from hair at far lower concentrations than observed in other methods (e.g., urine or saliva), making hair testing one of the most challenging practices.
Final Confirmation of any positive screening outcome employs analysis like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation. The whole lab process from Accessioning through to Confirmation follows review under the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly dubbed "hair follicle tests," the evaluation itself focuses on the hair strands, not the follicles below the scalp.
In Edgar, TX, hair follicle testing is proving superior to urine testing in several ways. Unlike urine tests, hair testing provides better detection accuracy and reliability, identifying drug usage over a more extended time frame.
