A Diagnostic to Drool Over?

At a Glance

  • Liquid biopsy is a rapidly evolving field that commonly uses blood and urine as source material for diagnostic tools
  • Despite the volume of saliva humans produce each day – 1 liter – the fluid isn’t currently used for the detection of circulating tumor DNA
  • Saliva contains genetic material and proteins, and can be collected through noninvasive techniques
  • David Wong, who has been working on “saliva-omics” for 12 years, hopes to curb negative social and cultural associations to advance saliva as a diagnostic fluid

New diagnostic methods continually arise – something that is driven by our determination to detect disease as early as possible, and thus give patients the best chance of successful treatment. Although liquid biopsy testing has primarily focused on blood, an innovative approach seeks to use an even less invasive bodily fluid – saliva.

About the Author

Luke Turner

While completing my undergraduate degree in Biology, I soon discovered that my passion and strength was for writing about science rather than working in the lab. My master’s degree in Science Communication allowed me to develop my science writing skills and I was lucky enough to come to Texere Publishing straight from University. Here I am given the opportunity to write about cutting edge research and engage with leading scientists, while also being part of a fantastic team!
