Accredited Drug Testing provides comprehensive hair follicle drug exams in Shell Knob, Missouri. If a hair or alcohol drug evaluation is what you need, Accredited Drug Testing excels in hair assessments with centers across various cities nationwide capable of conducting them. Typically, 1.5 to 2 inches of head or body hair is necessary. Hair samples can be assessed for drugs, alcohol/ETG, and other hair-specific options.
The hair follicle method has become more popular in recent times for drug screening purposes. Numerous employers, judicial systems, and substance abuse specialists demand hair drug exams instead of traditional urine ones. Companies enforcing strict no-drug policies, courts, and probation cases often use these tests. The main advantage of hair follicle exams is the extensive detection window, lasting up to 90 days, conducted under observation, making evasion nearly impossible, though urine tests are more precise for recent consumption within 5 days.

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term profile of substances by incorporating biomarkers into the growing hair fibers. When taken near the scalp, hair samples can reveal substance usage for a period extending up to roughly three months. Hair is easy to gather, relatively hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches and comprising roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp yields about 100mg of hair, which is optimal for both screening and confirming results. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. It’s advisable to measure the sample weight with a jeweler’s scale. If scalp hair is unavailable, a comparable quantity of body hair can be used. When mentioning head hair, we specifically refer to scalp hair. Body hair pertains to all other types of hair (facial, axillary, etc.).
Process Overview
The principal steps involved in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary steps required to incorporate a sample into a laboratory database. It involves validating that the sample was sealed and transported appropriately, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry missing from an electronic chain of custody system.
Screening is a preliminary check for the presence of drugs. While Screening serves as a cost-efficient method to exclude drug usage in most cases, any positive screen must undergo confirmation before it is acceptable in legal settings. Any samples that show a presumptive positive during Screening necessitate further confirmation.
If a sample shows a presumptive positive during Screening, additional hair is extracted from the original specimen to prepare for Extraction. In this phase, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or saliva), which makes hair drug screening one of the most challenging methodologies.
Confirming a positive screening involves GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as required. The entire procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and the accreditation under ISO / IEC 17025 standards.
