Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and drug use by embedding biomarkers within its growing fibers. If taken from near the scalp, hair samples can reveal drug and alcohol use for up to three months. The collection process is straightforward, with low risk of tampering, and shipping is uncomplicated.
A 1.5-inch segment of about 200 strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, which is optimal for screening and verification. For tests like EtG or those exceeding 10 panels, 150mg is advised. We suggest using a jeweler's scale for weighing. If scalp hair isn't available, an equivalent amount of body hair can be used. When mentioning head hair, we mean scalp hair only. Meanwhile, body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing for drug testing comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into the lab's system initially. This step confirms the sample's proper sealing and shipping, assigns a LAN (Laboratory Accessioning Number), and completes any extra data processing not managed by an electronic chain of custody system.
Screening conducts an initial, rapid assessment for substances. Though cost-effective for excluding drug use in most samples, a positive screen must be substantiated for legal acceptance. Presumptive positive results in Screening demand further confirmation.
If Screening indicates a presumptive positive, additional hair is obtained from the original sample for Extraction. Here, drugs are isolated at much lower concentrations compared to methods like urine or oral fluid tests, making hair drug testing particularly complex.
Positive results from screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing presumptive positivity are cleaned before confirmation if necessary. The complete lab procedure from Accessioning through Confirmation complies with both the CAP's Hair standards and ISO / IEC 17025 accreditation.
