Regarded as an influential instrument in identifying drug and alcohol consumption, hair testing offers comprehensive insights. The fibers of a developing hair strand encase biomarkers, providing an extended record of substance use. When sampled from near the scalp, hair can offer a detection span of up to about 90 days for substances. Hair is easy to gather, resistant to tampering, and convenient for mailing.
A sample measuring 1.5 inches with approximately 200 hair strands (similar to the diameter of a #2 pencil) adjacent to the scalp will yield 100mg of hair, the optimal amount for analysis and verification. For EtG, supplementary tests, and/or panels exceeding 10, a 150mg sample is advised. It's suggested to weigh the sample on a jeweler’s scale. Should scalp hair be unobtainable, a comparable quantity of body hair can be used. References to head hair specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails integrating a sample into a lab's system initially. Steps include checking that the sample was appropriately sealed and dispatched, allocating a randomized LAN (Laboratory Accessioning Number), and fulfilling any extra data entry absent in an electronic chain of custody system.
Screening consists of a preliminary rapid examination for substances of misuse. Although Screening economically eliminates drug usage in most samples, a confirmed positive result is needed for legal acceptability. All samples with a presumptive positive screening must undergo further confirmation.
When a sample shows a potential positive result in Screening, an additional portion of hair is retrieved from the original sample and readied for Extraction. Here, drugs are isolated from hair at much lower concentrations than in other techniques (such as urine or oral fluid), highlighting the complexity of hair drug screening.
Confirming any positive screening outcomes involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples undergo washing before confirmation if necessary. From Accessioning to Confirmation, the whole lab process is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 certification standards.
