Scientists Identified a Biological Signature of Tinnitus, And It's in Your Blood

Scientists found a blood protein called prestin that is about 50% higher in people with tinnitus, which could lead to the first objective test for the condition.

For the millions worldwide with tinnitus, silence never comes.

The Long Sip
What happened

Researchers have identified a blood protein called prestin that appears strongly linked to tinnitus, offering the first potential objective biomarker for the condition.

The detail

In a study of 82 adults, those with tinnitus had prestin concentrations in their blood roughly 50 percent higher than those without the condition.

What it means

The study found an association, not a proven cause, but it raises hope that a simple blood test for tinnitus could one day replace relying solely on a patient's own description.

For you

There is no diagnostic test yet, but ask your GP about tinnitus if you have persistent ringing, as this research may eventually lead to a blood test.

What readers are saying

NannaJase
the key bit most people will miss is that prestin levels get altered by noise exposure and age, so it's not just tinnitus causing high prestin - it's probably the other way around or both feeding each other. means a blood test might eventually tell you if your ears are damaged before you even notice the ringing.
