An effective method for detecting drug and alcohol consumption is hair analysis. Hair captures a long-term record of substances by embedding indicators within the strands as they grow. By collecting hair near the scalp, it can present a detection timeline for alcohol and other drugs extending up to roughly 3 months. The collection of hair is straightforward, relatively hard to tamper with, and simple to transport.
Acquiring a 1.5-inch portion consisting of approximately 200 hair strands (similar in size to a standard #2 pencil) nearest to the scalp results in 100mg, which is the optimal sample for initial testing and subsequent confirmation. For greater analytical requests such as EtG, additional tests, and/or those exceeding 10 panels, a specimen weight of 150mg is advisable. It is recommended to weigh the sample using a jeweler’s scale. Should scalp hair not be available, an equivalent quantity of body hair can be used. Specifically, head hair refers only to scalp hair, while body hair encompasses all other hair (including facial and axillary hair).
Process Overview
The laboratory processing for a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial sample entry into the lab system, verifying proper seal and shipment, assigning a random Laboratory Accessioning Number (LAN), and completing any necessary data entry not covered by an electronic chain of custody.
Screening serves as a preliminary check for drug abuse substances. Although it provides a cost-efficient measure to rule out drug presence on a majority of samples, any positive results from Screening must undergo confirmation to be viable in legal situations. Samples that test presumptively positive in Screening must proceed to a verification stage.
For samples testing presumptive positive in Screening, additional hair is extracted from the initial collection and prepared for the Extraction stage. In this phase, the concentration of drugs is isolated from hair at a notably lower concentration compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing methodologies.
Confirmation of positive Screening outcomes employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are appropriately cleaned before confirmation if necessary. The entire lab procedure from Accessioning to Confirmation undergoes verification under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Note: Although frequently called "hair follicle tests", the test analyzes the hair strand itself, not the follicle beneath the scalp.
Why Hair Follicle Testing Beats Urine Testing
In Caledonia, MN, the benefits of hair follicle testing significantly overshadow those of urine testing. With hair analysis, you secure superior detection accuracy and reliability. Unlike urine tests, which identify only recent usage, hair tests can reveal drug intake over a much longer timeframe. This makes hair testing an excellent choice for those enforcing strict substance policies.
The extended detection window of hair testing provides a broader overview of an individual's drug use history, covering up to 90 days. This allows employers to better assess the true habits of employees or candidates. Moreover, the collection of hair samples is less invasive and reduces the chances of tampering, preserving the integrity of each test.
Extended Detection Window
One of the standout features of hair follicle testing in Caledonia, MN, is its extended detection window. With a capability to trace substance use for up to 90 days, it covers a broader evaluation period compared to other methods. Employers can gain a clear, extensive view of an individual's history with substances, aiding in informed decision-making.
