DNA / Paternity Testing

We proudly offer DNA Testing for both legal reasons and peace of mind.

A DNA paternity test can definitively determine the biological father of a child.

DNA paternity testing compares a child’s DNA pattern with that of the assumed father to determine if there is a match. Testing by an experienced, accredited laboratory, is the most definitive proof of a biological relationship.

If you need paternity test results to be used as a legal document, a DNA Test must be performed.

A business with a drug-free workplace is less likely to have drug-related incidents such as accidents, tardiness, missed days of work, decreased productivity, fines, and lawsuits.

Even one drug-affected employee could cause a huge liability, or hurt other employees and the public, or destroy a business’ brand.

A primary purpose for our existence is to help ensure safety in the workplace by making sure businesses are free of substance abuse.

I Was In and Out Quickly

Came for a drug test for a job, the staff was friendly and I was in and out quickly. The technician explained the process thoroughly and let me know I would be contacted by my employer.
