Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures long-term data on alcohol and drug use by embedding biomarkers within the fibers of the hair as it grows. Sampling hair near the scalp can offer up to a three-month detection window for alcohol and drug substances. Hair collection is straightforward, difficult to tamper with, and simple to transport.
A 1.5-inch segment of around 200 hair strands (approximately resembling a #2 pencil) closest to the scalp can yield 100mg of hair, which is the optimal amount for testing and verification. For EtG, additional tests, or panels exceeding 10, it is suggested to collect 150mg of the sample. Use a jeweler’s scale for precise measurement of the sample. If scalp hair is not available, an equivalent portion of body hair can be used. "Head hair" specifically refers to scalp hair, whereas "body hair" covers all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. This involves ensuring the sample was sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and filling in any additional data not supplied by an electronic chain of custody system.
Screening serves as a preliminary check for drugs. Although Screening is a budget-friendly strategy to eliminate drug use on many samples, a positive result must be verified to be considered valid in a legal setting. Samples that show presumptive positivity in Screening necessitate additional confirmation.
If a sample tests presumptively positive during Screening, more hair is taken from the original sample and prepared for Extraction. Here, drugs are extracted at significantly lower concentrations from hair compared to other methods (such as urine or oral fluid), which makes hair drug screening particularly challenging to conduct.
Confirmation for any positive Screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive are cleaned before Confirmation as required. From Accessioning to Confirmation, the entire lab process is scrutinized under both CAP (College of American Pathologists) Hair standards and the accreditation of ISO / IEC 17025 standards.
