Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair accumulates a lasting record of these substances by embedding biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair can offer an approximate 3-month detection period for alcohol and various drugs. Hair collection is straightforward, moderately resistant to tampering, and convenient to transport.
A 1.5-inch section comprising around 200 hair strands (roughly equivalent to the width of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal quantity for screening and verification. For EtG, additional substances, and/or tests exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent quantity of body hair can be obtained. References to head hair exclusively pertain to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the laboratory’s system. This step verifies that the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any necessary data entry absent from an electronic chain of custody system.
Screening offers a preliminary assessment for potential drug use. Though Screening is a cost-efficient method for ruling out drug usage in most samples, a positive screen requires confirmation to be legally valid. Any samples that yield a presumptive positive in Screening necessitate further confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is extracted from the original specimen for the Extraction process. During this phase, drugs are isolated from hair at a significantly lower concentration than in other methods (such as urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation as needed. The comprehensive laboratory process, from Accessioning to Confirmation, is conducted in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", the analysis actually examines the hair strand rather than the follicle beneath the scalp.
