How can DNA testing help?
Bacterial samples from patients usually need to be cultivated and propagated in the laboratory, which is time consuming and difficult to confirm the diagnosis of pneumonia.
According to a paper published in the journal Critical Care, this test takes a different approach of detecting the DNA of various pathogens, allowing for faster and more accurate testing.
This test uses multiple polymerase chain reactions (PCRs) that detect bacterial DNA and can be done in about 4 hours. That is, you don’t have to wait for the bacteria to grow.
What is your future path?
IT can run multiple PCR reactions in parallel to simultaneously detect 52 different pathogens that often infect the lungs of patients in the intensive care unit.At the same time, you can also test Antibiotics resistance.
“Patients with Covid-19 are more likely to develop secondary pneumonia, but the bacteria that caused these infections were found to be similar to those in ICU patients without Covid-19,” Varsity said. Lead author Mailis Maes said.
“This means that standard antibiotic protocols can be applied to Covid-19 patients,” Maes added.
