The practice of hair testing is regarded as a robust method for identifying drug and alcohol usage. Hair strands preserve a timeline of alcohol and drug consumption by encapsulating biomarkers within the fibers as hair grows. Obtained near the scalp, hair can reveal substance intake for up to a three-month period. The collection process is straightforward, tampering is relatively challenging, and it's easily transportable.
A sample of 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp provides 100mg, which is optimal for testing and verification. For EtG, add-ons, and tests exceeding 10 panels, a 150mg sample is preferable. It's advisable to measure the sample with a jeweler’s scale. If scalp hair is insufficient, an equivalent amount of body hair can be taken. Head hair specifically refers to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves entering the sample into the lab's database. This step includes ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry missing from an electronic chain of custody.
Screening serves as a preliminary check for drug presence. Although Screening efficiently excludes drug usage for most samples, a positive indication must be validated to stand in legal settings. Samples testing positive in Screening necessitate a supplementary confirmation process.
Upon a presumptive positive result during Screening, additional hair from the original specimen undergoes Extraction. At this juncture, drugs are separated from hair at concentrations considerably lower than with other methods (such as urine or oral fluids), marking hair drug screening as a notably challenging procedure.
GC/MS, GC/MS/MS, or LC/MS/MS methods confirm any positive outcomes from Screening. All presumptive positive specimens are cleansed before confirmation when necessary. The comprehensive laboratory work, from Accessioning to Confirmation, aligns with standards set by both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the procedure examines the hair strand, not the follicle beneath the scalp.
