The utilization of hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. By capturing biomarkers within the strands of hair, which grows continuously, a detailed record of substance use is formed. When collected near the scalp, hair testing can uncover substance use for up to three months. This method is easy to gather, hard to tamper with, and straightforward to send off for analysis.
A sample close to the scalp, measuring 1.5 inches and comprising roughly 200 hairs (comparable to a #2 pencil in thickness), provides 100mg of hair, the ideal amount for both initial screening and subsequent verification. For the detection of EtG, expanded panels, or assays exceeding 10 panels, a larger sample of 150mg is advisable. It's best to weigh the sample using a jeweler's scale. If scalp hair is impossible to collect, an equivalent measure of body hair can be used instead. When we mention head hair, we exclusively refer to scalp hair. Body hair includes all other hair types, such as facial or underarm hair.
Process Overview
There are four primary stages in the lab analysis of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is entered into the lab's system. This procedure checks that the sample is sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry not handled by a digital chain of custody system.
Screening offers a preliminary assessment for the presence of illicit substances. While this step is an efficient method for eliminating drug use in most samples, a positive result must be confirmed for legal admissibility. Samples that show a presumptive positive in Screening are then subjected to further Confirmation testing.
When a Screening test indicates a probable positive, additional hair is taken from the original sample for the Extraction process. During this phase, drugs are extracted from the hair in significantly lower amounts than other techniques like urine or oral fluid, making hair drug testing one of the most challenging testing methods.
The Confirmation stage for any positive result uses GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples with presumptive positives are cleansed before confirmation if required. The complete examination from Accessioning through Confirmation adheres to the CAP (College of American Pathologists) standards for Hair and meets ISO / IEC 17025 accreditation requirements.

Limitations:
Note: Although commonly termed "hair follicle tests," the analysis is conducted on the hair strand itself, not the follicle beneath the scalp.
