The use of hair testing has emerged as an effective method to identify drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug presence by capturing biomarkers within the strands as they develop. When hair is gathered close to the scalp, it can reveal a detection span of nearly three months for alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch section comprising around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both analysis and confirmation. For EtG, additional, or multi-panel tests over 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale to measure the sample. If scalp hair isn’t available, the same quantity of body hair can be utilized. "Head hair" specifically refers to scalp hair. "Body hair" entails all other types of hair (facial, axillary, etc.).
Process Overview
There are four pivotal steps in a lab's processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample within a lab's system. This includes ensuring the sample's seal and proper dispatch, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent in an electronic chain of custody system.
Screening provides an initial assessment for substances of abuse. Though Screening is a cost-effective methodology to eliminate drug use in most samples, a single positive result must be validated to be legally acceptable. Samples considered presumptively positive in the Screening stage need a follow-up confirmation.
Should a specimen be tentatively positive during Screening, additional hair is retrieved from the original sample and set aside for Extraction. In this phase, drugs are separated from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), which makes hair drug screening the most complex methodology.
Confirmation of any positive result from screening is executed using GC/MS, GC/MS/MS or LC/MS/MS. All samples with positive indications are cleansed before confirmation when necessary. The entire testing procedure from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and in line with ISO / IEC 17025 standards.
