Regarded as an effective means for identifying drug and alcohol consumption, hair testing offers a comprehensive timeline for detecting substances by binding biomarkers within the strands of growing hair. When collected close to the scalp, hair can reveal alcohol and drug use over approximately a 3-month detection period. The collection process for hair is straightforward, tough to tamper with, and convenient for transport.
A sample measuring 1.5 inches consisting of roughly 200 strands of hair (comparable in size to a #2 pencil) nearest the scalp amounts to 100mg of hair, ideal for testing and validation. For tests exceeding 10 panels, along with EtG and additional tests, 150mg of hair is advised. It is recommended to weigh the sample using a jeweler’s scale. If scalp hair is absent, an equivalent quantity of body hair can be used. In the context of head hair, we specifically mean scalp hair. Body hair encompasses all other hair varieties (such as facial, axillary, etc.).
Process Overview
The drug test procedure in a laboratory consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial phases of incorporating a sample into a lab's system, ensuring proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and fulfilling additional data tasks not incorporated in an electronic chain of custody system.
During Screening, a preliminary assessment for drugs of abuse is conducted. While Screening serves as a cost-efficient method to eliminate drug use for most samples, confirmation is necessary for any positive result to be valid in court. Samples showing presumptive positive results in Screening require a secondary confirmation.
If a sample presents presumptive positives in Screening, more hair is taken from the original sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations than other methods (like urine or oral fluid), hence making hair drug testing a challenging methodology.
Confirmation of positive screening outcomes is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive are cleansed prior to confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is assessed under the guidelines of both the CAP (College of American Pathologists) Hair designation and meets the accreditation standards of ISO/IEC 17025.
