Scientists develop diagnostic test for chronic fatigue

CFS sufferers can often have their symptoms written off as malingering, because the diagnostic test results for organ function and blood and immune cell counts all are normal in these patients.

The new test is based on how a person’s immune cells respond to stress. It is powered by a diagnostic technology that comprises electrodes to produce electrical current, and chambers to hold blood samples containing immune cells and plasma.

In the chambers, the presence of immune cells and plasma interferes with the current and changes its flow. This change in electrical activity is directly linked to the health of the sample.
