With what is believed to be the first test of its kind, Sunnybrook scientists have demonstrated a way to detect hearing disorders using a simple blood test.
The research has been published in Biosensors and Bioelectronics.
“Over 600 million people have hearing loss worldwide including 3.5 million Canadians. In 20 years, as the population ages, that number is likely to increase to 1 billion, says Dr. Alain Dabdoub, co-author of the study, senior scientist and research director of the Sonja N. Koerner Hearing Regeneration Laboratory at Sunnybrook Research Institute.
“Current approaches for detecting hearing disorders are mostly based on physical examinations and cannot provide information about the exact location of the cellular damage within the inner ear. There is a need for a new more precise method to identify sites of damage.”
The researchers note the test holds great promise for point-of-care diagnostics and will eventually allow for more precise treatments. “Being able to localize cellular damage will enable us to better personalize treatment,” says Dr. Dabdoub. “This will eventually lead to improved quality of life for patients living with hearing and balance disorders.”
