Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis is now recognized as a robust method for identifying drug and alcohol consumption. Hair captures a lengthy record of substance use by holding biomarkers within the strands that grow. Sampling hair near the scalp offers approximately a three-month detection period for drugs and alcohol. Hair is easy to gather, somewhat challenging to tamper with, and simple to transport.
A hair sample measuring 1.5 inches in length, comprising around 200 strands (similar in size to a #2 pencil) from the scalp will yield 100mg of hair, which is the preferred amount for screenings and confirmations. For EtG, additional tests, or more than 10 panels, a collection of 150mg is advised. Using a jeweler’s scale for weighing the specimen is recommended. If hair from the scalp cannot be obtained, an equivalent quantity of body hair can be used. Scalp hair specifically refers to hair on the head, while body hair covers all other types such as facial and axillary hair.
Process Overview
There are four key stages in processing a drug test result in a laboratory: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the lab’s system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any manual data entry not covered by electronic chain of custody systems.
The Screening phase includes a preliminary rapid test for substances. Although Screening efficiently rules out drug use for most samples, confirmation is necessary for court use if results are positive. Samples showing presumptive positives during Screening require further confirmation.
When a sample is presumptively positive at the Screening phase, an additional portion is taken for Extraction. In this phase, drugs are extracted from hair at significantly lower levels than other methods like urine or oral fluid testing, making hair drug analysis the most challenging to execute.
Confirmation of any positive Screening outcome uses GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing as needed before confirmation. The end-to-end processing from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often termed "hair follicle tests," the evaluation targets the hair strand itself, not the follicle from beneath the scalp.
