Blood test could identify people who will respond to antidepressants

Patients will potentially be able to avoid medications that do not help them and the test could start a 'new era' for personalised treatment of depression

Scientists have developed a blood test that could identify which people with depression will respond to treatment so that patients can avoid spending months taking antidepressants that do not help them.

The experts involved believe the breakthrough could lead to depressed patients receiving personalised treatments that are more likely to relieve their symptoms.
