What is a TDT TEST (TONE DECAY TEST) Test in Bengaluru ?
What is TDT TEST (TONE DECAY TEST)?
The Tone Decay Test (TDT) measures how long a person can hear a steady pure tone presented at a comfortable loudness. It checks whether the ear and auditory nerve keep responding over time. Physical examination provides clues; a test result removes ambiguity and allows targeted, evidence-based management to begin promptly.
What does TDT TEST (TONE DECAY TEST) measure?
This is important because a rapid decrease in hearing of the tone can suggest nerve or retrocochlear problems rather than just inner ear (cochlear) loss. Doctors use TDT alongside hearing tests and speech tests. It helps decide whether further investigations, like imaging or specialist referral, are needed to look for tumors, nerve disorders, or certain neurological diseases. The test is quick and done in a sound-treated room by an audiologist.
What symptoms suggest TDT TEST (TONE DECAY TEST) may be needed?
A doctor may recommend TDT TEST (TONE DECAY TEST) when a patient reports any symptom your doctor has identified as requiring objective laboratory investigation , including unexplained fatigue, unexplained weight change, persistent pain, fever, or abnormal bleeding. Sample collection for Bengaluru is available at labs and at home across Bannerghatta Road, Marathahalli, and surrounding neighbourhoods.
