The assessment of hair samples is increasingly recognized as an effective means for detecting substance and alcohol usage. These samples embed markers within the fibers of the hair as it grows, offering an extended timeline of substance exposure. Collected proximal to the scalp, such samples can reveal a usage window of up to 90 days for substances, including alcohol. Hair collection is straightforward, relatively tamper-resistant, and convenient for transportation.
A 1.5-inch sample comprising roughly 200 strands of hair (comparable to a #2 pencil) taken near the scalp will yield 100mg, the ideal quantity for initial screening and subsequent confirmation. For EtG testing, additional tests, or panels exceeding 10, a 150mg sample is advisable. It's best to measure the sample weight with a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair can be used. When we refer to head hair, we mean scalp hair only; body hair includes all other types (such as facial or axillary hair).
Process Overview
The laboratory procedure for processing drug test outcomes involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where the sample is integrated into the lab's system. This involves confirming that the sample was properly sealed and sent, assigning a LAN (Laboratory Accessioning Number) randomly, and performing any remaining data entry absent from an electronic chain of custody.
Screening is an initial analysis to identify illicit substances. While it's cost-efficient for excluding drug use in the majority of samples, a positive result from Screening necessitates further Confirmation to stand in court. Samples that test presumptively positive during Screening require additional verification.
Should a sample test presumptively positive during Screening, additional hair is extracted from the original sample and readied for the Extraction phase. Here, substances are drawn out from the hair at a much lower concentration compared to other methods (such as urine or oral fluid), highlighting the complexity of hair drug analysis.
The Confirmation stage for any positive findings obtained during Screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo cleansing prior to confirmation as warranted. The entirety of this lab course, from Accessioning through Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair standards and accredited to ISO / IEC 17025 specifications.
