Recently, drug testing methods have seen increased reliance on hair follicle tests. Various employers, courts, and substance abuse professionals now opt for hair drug tests instead of traditional urine tests. This approach is favored by employers with zero tolerance for drugs and individuals on probation due to its longer detection period, which can reach up to 90 days, is collected with direct observation, and it's hard to tamper with. Urine tests remain more precise for drug use in the past five days.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair evaluation has emerged as an effective instrument for identifying substance and alcohol consumption. Hair offers a prolonged record of alcohol and other substances by capturing biomarkers within the fibers of evolving hair strands. When taken close to the scalp, it can yield approximately a 3-month detection period for alcohol and other drugs. Hair collection is straightforward, fairly tamper-resistant, and convenient to transport.
A 1.5-inch length of around 200 hair strands (comparable to the width of a #2 pencil) near the scalp will provide 100mg of hair, the optimal sample for analysis and confirmation. For EtG, additional assessments, or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest weighing the sample using a jeweler's scale. If scalp hair isn't accessible, a comparable quantity of body hair may be gathered. The term "head hair" specifically refers to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample within a laboratory's system. This step includes ensuring the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.
Screening serves as an initial rapid evaluation for detectable drugs. While Screening efficiently rules out drug use in most samples, a positive screen necessitates confirmation for court proceedings. Samples that are presumptively positive during Screening mandate a follow-up confirmation.
If a sample tests presumptively positive during Screening, additional hair is sourced from the original specimen and prepared for Extraction. In this phase, substances are extracted from hair at a significantly lower concentration than through other methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology.
Any positive screening result is verified via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair category and accredited to ISO / IEC 17025 standards.
