Accredited Drug Testing provides comprehensive hair drug testing services in Winchester, Washington. Specializing in hair and alcohol testing, our nationwide centers are equipped to perform these tests. Typically, 1.5 to 2 inches of hair is necessary from the scalp or body. This method can test for drugs, alcohol/ETG, and customized hair options.
Recent trends in drug testing have increasingly favored hair follicle tests over urine tests. Employers, courts, and Substance Abuse professionals often prefer hair testing due to its extended detection capabilities, up to 90 days, and its observed collection process which minimizes tampering. However, for drug use within the last 5 days, urine tests remain more precise.

Hair analysis is increasingly recognized as a formidable means for identifying alcohol and drug consumption. Hair fibers capture long-lasting biomarkers as the strand progresses, providing extensive historical data. Collected near the scalp, hair samples can reveal substance use over approximately a 90-day span. Collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment containing roughly 200 hair strands (akin to a #2 pencil’s width) near the scalp yields 100mg of hair, the optimal amount for both screening and validation. For EtG, supplementary tests, or assessments exceeding 10 panels, 150mg of the sample is advised. Use a jeweler’s scale for precision weighing. In the absence of scalp hair, equivalent body hair may be an alternative. The term "head hair" specifically denotes scalp hair, whereas "body hair" covers all other types (such as facial, axillary, etc.).
Process Overview
The laboratory progression for analyzing a drug test sample unfolds through four principal stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing within the laboratory's framework. This entails confirmation that the sample remains sealed and correctly dispatched, attribution of a random Laboratory Accessioning Number (LAN), and completion of any supplementary data input absent from an electronic chain of custody.
Screening provides a preliminary examination for drug presence. Although a cost-efficient method for excluding drug use in most cases, a positive result at Screening necessitates further verification to uphold in legal settings. Samples returning a presumptive positive result from Screening require secondary corroboration.
Should a sample yield a presumptive positive result during Screening, additional hair is extracted from the original specimen for the Extraction process. Here, drug concentrations are isolated from hair at significantly lower levels compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
Confirmation of any presumptive positives from Screening employs techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with potential positive results are cleaned prior to Confirmation as needed. The entire procedure from Accessioning through Confirmation is scrutinized under CAP's Hair guidance and the ISO / IEC 17025 standards.
