What is DNA Testing?

Understanding DNA Testing: Science, Accuracy, and Applications
DNA testing is a scientific method used to analyze an individual’s genetic material (DNA) to determine biological relationships, ancestry, medical conditions, and personal identity. It is one of the most accurate and reliable ways to confirm family connections, genetic traits, and even potential health risks.
At Guardian Testing Solutions, we specialize in highly accurate and legally recognized DNA testing for individuals, families, legal cases, and immigration purposes.

How Does DNA Testing Work?

DNA (deoxyribonucleic acid) is the genetic code that makes up every living organism. Each person inherits half of their DNA from their mother and half from their father, making it possible to analyze relationships and genetic connections.

The DNA testing process is simple, painless, and highly precise:
1️⃣ Sample Collection – DNA is collected using a non-invasive buccal (cheek) swab or, in some cases, blood or saliva samples.
2️⃣ Laboratory Analysis – The DNA sample is analyzed in an accredited laboratory to compare genetic markers.
3️⃣ Result Interpretation – The laboratory identifies matching DNA sequences to determine biological relationships, ancestry, or health information.
4️⃣ Official Results – Depending on the type of test, results are delivered in 5-10 business days, with options for expedited processing.

All tests performed by Guardian Testing Solutions follow strict scientific protocols to ensure 99.99% accuracy.
