Is A Saliva DNA Test As Accurate As A Blood Test?Updated 3 hours ago

Yes, saliva-based DNA tests are just as accurate as blood-based tests for hereditary genetic testing. The DNA found in buccal cells, collected from saliva, is the same as the DNA found in blood cells. This means both sample types deliver equivalent accuracy when analyzing inherited genetic variations.

At CircleDNA, we use a simple cheek swab to collect your sample. This method is quick, painless, and convenient, while still providing laboratory-grade accuracy. Our accredited lab uses Next Generation Sequencing (NGS), which achieves over 99.9 percent analytical accuracy. This ensures you receive reliable, high-quality insights whether your DNA comes from saliva or blood.
