Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug usage by embedding biomarkers within the strands of the growing hair. When collected close to the scalp, hair can offer up to a three-month detection timeframe for substances such as alcohol and other drugs. It is straightforward to collect, somewhat resistant to tampering, and convenient to transport.
A sample size of 1.5-inches, comprising approximately 200 hair strands (similar to the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is optimal for screening and verification. For Ethyl Glucuronide (EtG), additional tests, and/or more than 10-panel tests, a quantity of 150mg is advisable. It is suggested to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair can be gathered. References to head hair relate specifically to scalp hair. In contrast, body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four central steps in the laboratory process for analyzing drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample within a laboratory’s system. It entails confirming the sample's proper sealing and shipping, assigning a random Laboratory Accessioning Number (LAN), and fulfilling any other data entry absent from an electronic chain of custody system.
Screening serves as an initial swift assessment for drugs of misuse. Although Screening is an economical means to exclude drug consumption in most samples, a positive result requires verification for it to be legally valid. Samples exhibiting presumptive positive results in Screening necessitate a secondary confirmation.
If a sample yields a presumptive positive in Screening, additional hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are isolated from hair at lower concentrations than in other techniques (e.g., urine or oral fluid), which makes hair drug analysis the most intricate methodology to implement.
Confirmation of any positive result from screening is performed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a cleansing process prior to confirmation if deemed necessary. The comprehensive laboratory procedure, ranging from Accessioning to Confirmation, is assessed following both the College of American Pathologists (CAP) Hair designation and the ISO / IEC 17025 accreditation standards.
