If a hair or alcohol test is what you require, this company excels in hair-based testing and has facilities across all U.S. cities. Generally, 1.5 to 2 inches of hair from the head's crown or body is needed. Hair analyses cover drugs, alcohol/ETG, and offer other tailored options.
Over recent years, using hair follicle drug tests for substance screening has grown more common. A lot of employers, legal bodies, and substance abuse experts are now opting for hair tests over urine samples. Hair follicle evaluations are chosen by organizations with strict anti-drug policies, legal systems, and probationers. Their key advantage is a longer detection timeline—up to 90 days. The process is observed, making it hard to tamper with. However, urine tests remain the most precise for detecting recent drug use (within 5 days).

Hair testing is now recognized as an effective method for detecting drug and alcohol consumption. By capturing markers in the fibers of the growing hair, hair reveals a long-term record of alcohol and drug use. Collected near the scalp, hair can show a drug and alcohol detection window of around three months. The collection process is straightforward, hard to adulterate, and convenient to transport.
A 1.5-inch hair sample (about the thickness of a #2 pencil) containing approximately 200 strands closest to the scalp yields 100mg, an optimal amount for screening and confirmation processes. For EtG, additional analyses, or tests exceeding ten panels, 150mg is advised. It’s best to measure the specimen using a jeweler's scale. If scalp hair cannot be obtained, a similar quantity of body hair is acceptable. “Head hair” indicates scalp hair only, whereas “body hair” encompasses other types like facial or axillary hair.
Process Overview
The lab process for drug tests includes these primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial sample processing in a lab's system. This phase ensures the sample is correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry missing from an electronic chain of custody system.
Screening is a preliminary step to detect drugs of abuse. While it provides an economical method to exclude drug use in most specimens, any positive result here must be confirmed to be court-admissible. Samples that test presumptively positive in Screening must be further confirmed through additional testing.
Should a sample test presumptively positive during Screening, more hair from the original specimen is used for Extraction. Drugs in this phase are extracted at significantly lower concentrations than in methods like urine or oral fluid tests, making hair drug screening the most challenging method.
For Confirmation, positive screening outcomes are validated using GC/MS, GC/MS/MS, or LC/MS/MS methods. Every presumptively positive sample is subjected to washing before confirmation, if necessary. The overall laboratory procedure, from Accessioning to Confirmation, is reviewed accrediting both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
