Nearly all people hospitalized with COVID-19 develop antibodies against the virus within six days of testing positive, new research indicates.

A proposed platform uses nanoparticles or magnetic levitation to spot a "fingerprint" for COVID-19 diagnosis and checking death risk.

A new way to make reagents for COVID-19 testing could boost our capacity for testing and make producing future tests easier.

A biomarker in newborns may signal autism spectrum disorder months or even years before symptoms begin, say researchers.

Researchers make the case for a saliva test for COVID-19, rather than the nasal swabs currently in use.

A new COVID-19 test could be a lot simpler. “The idea is to have a paper-based system where people can just look at it and say, yes, you have it, or not.”

Engineers are solving problems with testing and treatment for COVID-19, including designing new medical equipment and better nasal swabs.

Though it's yet to be validated or approved by the FDA, a new potential test for COVID-19 could deliver results in less than 10 minutes.

"If we can [get a] result faster, that also protects our friends and loved ones... who are going into the clinic. My best friends are going to war."

It may one day be possible to detect prostate cancer from a simple, non-invasive urine test
