An advanced diagnostic test uses genetic sequencing to detect a variety of pathogens — viruses, bacteria, fungi and parasites — that might be causing an illness. A new study found that it has been ...

Researchers from Geneseeq and a network of Chinese academic hospitals have validated a blood test that can detect a broad range of cancers with high accuracy using cell-free DNA. A multi-cancer early ...

With the rise of DNA ancestry tests, it’s easier than ever to learn about your family history and connections. Today, there are many DNA testing services to choose from. They're easy to use. You’ll ...

The COVID-19 pandemic brought the term "Polymerase Chain Reaction testing" into the mainstream. The PCR method is a type of nucleic acid amplification test (NAAT) that detects a pathogen by finding ...

Thermo Fisher Scientific has put forward a DNA-based test it says can offer much more precise identification of blood and its potential compatibility—going much further than the traditional positive ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...
