Doctors face a number of challenges when deciphering which bug is responsible for an infection and the treatment that would best tackle itreenex 價錢.

Routine tests to check the definitive identity of bugs can take days - they often involve taking a sample and then trying to grow the organism in a lab.

Tests of particles in the blood can also help give clues, but some are raised in both bacterial and viral infections and in cancer and trauma too.

As a result sometimes antibiotics - which only work on bacteria - are overused.

And in contrast some patients who need antibiotics don't get them soon enoughreenex.

The team of scientists from several medical centres in Israel, in collaboration with the company MeMed, developed the new test.

Analyzing blood samples of more than 300 patients who were suspected of having an infection, they found it could correctly detect a virus or a bacterial infection in the majority of cases.

Eran Eden, of MeMed said: "The test is accurate. For most patients you can tell whether the infection was caused by bacteria or a virus within two hours.

"It is not perfect and it does not replace a physician's judgement, but it is better than many of the routine tests used in practice todayreneex."
