Accredited Drug Testing provides comprehensive hair follicle drug analysis in South Hill, Washington. If you require a hair-based test for drugs or alcohol, we are experts in this field, offering services from testing centers in cities Nationwide. Typically, a hair length of 1.5 to 2 inches on the head or body is needed. Hair assessments can evaluate drugs, alcohol/ETG, or can be tailored to specific requirements.
Recently, conducting drug tests has increasingly involved hair follicle analysis. This approach is favored by many employers, legal institutions, and substance abuse experts over standard urine tests. It is particularly used by organizations with strict drug-free policies, the judiciary, and for probation monitoring. The main advantage of hair drug testing is the extended detection window of up to 90 days, collected in a monitored setting, making cheating nearly impossible. For identifying drug use within the past five days, however, urine tests remain the most accurate.

Hair testing has emerged as a potent method for identifying drug and alcohol consumption. By encapsulating biomarkers within the fibers of the hair strand as it grows, hair offers an extended record of alcohol and drug intake. When samples are collected close to the scalp, they can provide a detection timeframe of up to 3 months for alcohol and drugs. Hair collection is straightforward, relatively secure against tampering, and convenient for transport.
To obtain the ideal sample for screening and confirmation, a 1.5-inch section of around 200 hair strands (roughly the size of a #2 pencil) near the scalp provides 100mg of hair. For EtG, additional tests, or panels exceeding 10, a specimen amount of 150mg is advisable. It is recommended to weigh the specimen using a jeweler’s scale. Should scalp hair be insufficient, a comparable quantity of body hair can be collected. When mentioning head hair, it specifically indicates scalp hair only, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug test result processing in the laboratory comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step in integrating a sample into the laboratory’s system. This step includes confirming the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent in an electronic chain of custody system.
Screening constitutes an initial rapid assessment for the presence of drugs of abuse. Although Screening is an economical approach to exclude drug usage in most samples, any positive screening must be validated to be legally admissible. Samples yielding presumptive positive results in Screening necessitate additional confirmation.
When a sample shows a positive preliminary result in the Screening phase, more hair from the initial collection is processed for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than those in other methods (e.g. urine or oral fluid), underscoring the complexity of hair drug screening.
The confirmation of a positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as required. The complete laboratory procedure, spanning from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
