Hair testing is recognized as an effective means for detecting substance and alcohol use. It provides a comprehensive historical record of substance intake by embedding biomarkers within the developing hair strands. When hair samples are taken near the scalp, they can offer up to a three-month detection period for both alcohol and drugs. Hair's collection process is straightforward, difficult to tamper with, and convenient for shipping.
A 1.5-inch segment of approximately 200 hair strands (roughly the size of a #2 pencil), cut closest to the scalp, will yield 100mg of hair—the optimal amount for both preliminary and confirmatory testing. For EtG, additional services, or tests exceeding 10 panels, a 150mg specimen is advisable. It is suggested to use a jeweler's scale for weighing the sample. In cases where scalp hair isn't accessible, an equivalent quantity of body hair can be used. When mentioning head hair, it pertains specifically to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary processing of a sample within a lab's framework. This step includes ensuring the sample's proper sealing and delivery, assigning a random Laboratory Accessioning Number (LAN), and finalizing any additional data entry not covered by an electronic chain of custody system.
Screening involves an initial rapid assessment for substance misuse. While Screening economically rules out drug presence in most samples, a positive Screening result must be confirmed for courtroom acceptance. Any samples with presumptive positives in Screening necessitate further confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction process. During Extraction, drugs are removed from hair at a significantly lower concentration than seen in other testing methods (e.g., urine or oral fluid), which makes hair drug testing particularly challenging.
Positive Screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleaned before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is thoroughly reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.
