Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of growing hair strands, hair serves as a long-term indicator of alcohol and other drug use. When collected near the scalp, hair testing can detect these substances over a period of up to three months. Hair samples are easy to collect, hard to tamper with, and straightforward to ship.
A 1.5-inch sample consisting of approximately 200 hair strands (roughly the size of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG add-ons and tests exceeding 10 panels, 150mg of the sample is advised. The specimen should be weighed using a jeweler’s scale. If scalp hair is unavailable, a comparable quantity of body hair can be used. When mentioning head hair, we specifically refer to scalp hair, while body hair includes all other types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating the sample into the lab’s system, which involves verifying the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry that isn't already furnished by an electronic chain of custody system.
Screening is a preliminary assessment for drugs of abuse, providing a cost-efficient means to rule out drug usage in most samples. However, to be legally admissible, a positive screen requires confirmation. Any samples that show a presumptive positive result in Screening must undergo a secondary confirmation process.
Should a sample test presumptively positive during Screening, additional hair is extracted from the initial specimen and prepared for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration compared to other methods (like urine or oral fluid), making hair drug screening a more challenging method to conduct.
Confirmation of positive screening results is achieved via techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptive positives are washed as necessary before confirmation. The full process from Accessioning to Confirmation is thoroughly reviewed under the CAP (College of American Pathologists) Hair program and accredited to ISO / IEC 17025 standards.
