How It Works

Collection

• In Harwood, TX, a collector will secure a hair specimen, usually from the crown, following strict chain-of-custody procedures.
• The secured sample is subsequently labeled and dispatched to a certified laboratory for analysis.
• If scalp hair is sparse, alternate collection sites, such as body hair, can be utilized.

Testing Methodology

• Harwood, TX's procedures ensure hair samples are washed and prepared to eliminate external contamination before testing.
• An immunoassay technique is first used to screen for various drug classes in Harwood, TX.
