Hair analysis is increasingly acknowledged as a significant means for identifying substance and alcohol consumption. It captures a prolonged timeline for various substances by embedding chemical markers within the strands as they grow. Collected near the scalp, it reveals a drug and alcohol usage history spanning up to about three months. Hair samples are straightforward to gather, challenging to tamper with, and convenient for shipping.
Securing a 1.5-inch segment comprising roughly 200 strands (similar to the circumference of a #2 pencil) adjacent to the scalp yields approximately 100mg, which suffices for comprehensive screening and verification. For the detection of EtG, additional assessments, or when exceeding 10 panels, 150mg is advised. We advise using a jeweler’s scale to measure the sample’s weight. When scalp hair is absent, an equivalent amount of body hair can be gathered. References to head hair imply scalp hair specifically. Body hair encompasses other types (e.g., facial, axillary).
Process Overview
The laboratory drug test result processing encompasses four vital steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step involving incorporating a sample into a lab’s workflow. It ensures the sample’s proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and completes any additional data entry not captured by an electronic custody system.
Screening provides a preliminary rapid assessment for drugs of misuse. Although it’s a budget-friendly option for excluding drug presence in most samples, court acceptance requires confirmation of positive results. Any samples testing presumptively positive in Screening need further confirmation.
When a sample tests presumptively positive during Screening, additional hair is retrieved from the initial sample for Extraction. Substances are isolated from hair at notably lower concentrations than with other approaches (e.g., urine, oral fluid), which accounts for the complexity of hair drug testing.
Positive Screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, presumptive positive samples are cleansed as necessary. The complete lab procedure from Accessioning to Confirmation is scrutinized according to both the College of American Pathologists (CAP) Hair guideline and the ISO / IEC 17025 certification standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly labeled as “hair follicle tests,” the analysis targets the hair strand instead of the follicle beneath the scalp.
