SYDNEY (Reuters) - Researchers in Australia have devised a test that can determine novel coronavirus infection in about 20 minutes using blood samples in what they say is a world-first breakthrough.
The researchers at Monash University said their test can determine if someone is currently infected and if they have been infected in the past.
"Short-term applications include rapid case identification and contact tracing to limit viral spread, while population screening to determine the extent of viral infection across communities is a longer-term need," the researchers said in a paper published in the journal ACS Sensors on Friday.
The research team was led by BioPRIA and Monash Universitys Chemical Engineering Department, including researchers from the ARC Centre of Excellence in Convergent BioNano Science and Technology (CBNS).

Hopefully they get the size of the blood sample down.
ON EDIT: DERP
Sometimes I need to slow it down when reading on small screens. Or just in general.

(66,520 posts)We're using in clinic right now a 20-minute test with a nasopharyngeal swab.
What we need is increased sensitivity and specificity.
Fewer false negative and false positives.

On careful reading, it's looking for agglutination (clumping) of blood cells. I am aware of other factors that commonly cause agglutination: dehydration, high blood sugar being extremely common ones.
