Looking for hair and nail drug testing near you in Signal Hill or Long Beach? HPC Testing Services provides fast, confidential, and reliable drug and alcohol testing. Our hair and nail tests detect substance use up to 90 days, offering a longer detection window than standard urine tests, which typically detect drugs only 3–5 days after use.
Why Choose Hair & Nail Testing?
Hair and nail testing is ideal for:
* Court cases and legal matters – provide evidence when needed
* Probation or parole monitoring – meet supervision requirements
* Child custody and family law cases – verify substance use for documentation
* Personal knowledge – peace of mind about substance use history
* Insurance or pre-legal documentation – long-term verification
Unlike urine tests, which show only recent use, hair and nail testing provides a 90-day history, making it perfect when long-term results are required.

2. Professional collection – private, confidential, and accurate
3. Laboratory analysis – certified, reliable results
