FAQ (Early Cancer Screening)

What is cfNA

(cell free nucleic Acid)?

When a cell dies, the nucleic acid (DNA/RNA) in the cell is released into the body fluid (such as blood or saliva). cfNA contains mutant DNA (ctDNA) released by cancer cells and a large amount of expressed RNA (ctRNA).

Early cancer screening using cfDNA/cfRNA from saliva Vs. Tumor cell medical image detection?

Early cancer screening using cfDNA/cfRNA from saliva will detect tumors <0.1 cm in size.

Traditional methods:

  • Orthophoto photography will detect tumors >0.6 cm in size.

  • NMR will detect tumors >0.6 cm in size.

  • Low-dose tomography will detect tumors >0.8 cm in size.

  • Ultrasonic examination will detect tumors >1.0 cm in size.

  • X-ray examination will detect tumors >1.0 cm in size.

What are saliva preservation tubes? 

Preservation tubes are required for collecting, preserving and transporting saliva samples prior to testing following a few simple steps:

1. Remove receptacle cap. 

2. Thread funnel onto receptacle.

3. Collect sample.

4. Discard funnel. 

5. Put receptacle cap back on.

6. Send the sample to our lab. 

Testing Process?

1. Our saliva preservation tubes can be used to collect saliva samples at home by following the enclosed easy-to-use instructions then mailed directly to our laboratory upon completion.

​2. Our technicians will then perform cfDNA/cfRNA purification and Real-time PCR analysis of the provided sample. 

​3. A complete test report and expert analysis will be available within 1 month.

How does cancer develop in the body?

Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.

What is early cancer screening?

The goal of early detection is to diagnose cancer as early as possible when no symptoms are present. Due to the limitations of medical testing technology, most cancers can only be detected when they reach 0.6 cm in size. Our cfDNA/cfRNA cancer screening technology will detect cancer cells <0.1 cm in size. This dramatically reduces the time to diagnosis allowing for early treatment and possible prevention.
