Australian researchers have been able to detect positive Covid-19 cases using blood samples in about 20 minutes and identify whether someone has contracted the virus, according to the study, published in the journal ACS Sensors.

• The research team developed a simple agglutination assay — an analysis to determine the presence and amount of a substance in the blood.

• Positive COVID-19 cases cause an agglutination or a clustering of red blood cells, which is easily identifiable.

• This breakthrough can help governments and health experts with contact tracing to limit community spread.

• More than 700 samples can be assessed each hour on high-grade diagnostic machines.

• Agglutination tests based on the commonly employed blood typing methods are a viable option since these blood typing tests are employed in hospitals worldwide with high-throughput, fast (10-30 min), and automated in most cases.

• According to the researchers, using a simple lab setup, this discovery could see medical practitioners across the world testing up to 200 blood samples an hour.
