Hair analysis has gained recognition as an effective means for assessing alcohol and drug use. Hair strands capture long-term markers by embedding them within the fibers of the hair as it grows. When collected near the scalp, hair offers up to a 3-month detection period for alcohol and various drugs. Hair is easy to collect, challenging to tamper with, and convenient for shipping.
A 1.5-inch portion containing around 200 hair strands (comparable in size to a #2 pencil) next to the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. We suggest using a jeweler's scale to weigh the sample. If scalp hair is not present, an equivalent amount of body hair can be taken. When we refer to head hair, it exclusively means scalp hair. Body hair includes all other hair types (like facial, axillary, etc.).
Process Overview
The four primary stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial processing into a lab's system, which includes confirming the sample's proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and performing any needed data entry absent from an electronic chain of custody.
Screening performs a swift initial check for drug abuse. Though Screening is affordable for negating drug use in most samples, court-admissible positives require confirmation. Presumptive positives from Screening necessitate additional verification.
If Screening suggests positivity, more hair is retrieved from the original specimen for Extraction. Drugs are extracted from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing particularly complex.
Positive screening confirmations use GC/MS, GC/MS/MS or LC/MS/MS techniques. Before confirmation, positive samples undergo washing as necessary. The lab process from Accessioning through Confirmation is reviewed under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards.
