Hair analysis has evolved into a critical technique for identifying drug and alcohol consumption. Hair retains a long-term record by embedding biomarkers in the braid of the expanding hair shaft. When taken near the scalp, hair can provide a window of detection for approximately up to 3 months for substances like alcohol and drugs. It's easy to gather, tricky to tamper with, and convenient to transport.
A segment of 1.5 inches involving around 200 hair strands (comparable to the diameter of a #2 pencil) close to the scalp gets you 100mg, which is the preferred sample size for evaluation and validation. For tests focusing on EtG, additional panels, or more than 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale for weighing the sample is recommended. If scalp hair is unavailable, a comparable quantity of body hair can be collected. When mentioning head hair, it's specifically the scalp hair. Body hair, on the other hand, encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into a lab's framework. It involves checking that the sample is sealed and sent accurately, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry not incorporated through an electronic custody chain.
Screening is an initial rapid examination for drug misuse. Although Screening is a cost-efficient method to discount drug consumption in most samples, any positive screen requires confirmation to be valid in a legal setting. Samples deemed presumptive positive during Screening necessitate a secondary confirmation.
Should a sample appear presumptively positive in Screening, additional hair is extracted from the original sample and readied for Extraction. At this stage, drugs are extracted from hair with much lower concentration compared to other methods (e.g., urine, oral fluid), which is why hair drug screening is considered the most challenging technique.
Confirming any positive screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation as necessary. The whole process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.
