An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone).
Hearing occurs when sound waves stimulate the nerves of the inner ear. The sound then travels along nerve pathways to the brain.
Sound waves can travel to the inner ear through the ear canal, eardrum, and bones of the middle ear (air conduction). They can also pass through the bones around and behind the ear (bone conduction).
An x-ray examination uses an electrical device to emit (put out) x-rays and digital technology to create two-dimensional pictures of internal body structures.
This test is particularly useful in diagnosing conditions or diseases that affect the bones and chest.
A conventional x-ray examination is non-invasive, painless and does not require any recovery time.
The dose of radiation from an x-ray examination is considered safe ? roughly the same as you would receive from the general environment in about one week.
A ketones in urine test measures ketone levels in your urine. Normally, the cells in your body use glucose (sugar) from your blood for energy. If your cells can’t get enough glucose, your body breaks down fat for energy instead. This produces an acid called ketones, which can build up in your blood and urine.
Having some ketones in your urine is normal. But high ketone levels in urine may be a sign that your body is too acidic. This condition is called ketoacidosis. The most common type of ketoacidosis is a complication of diabetes called diabetic ketoacidosis (DKA). Diabetic ketoacidosis is a medical emergency that often develops quickly and can even be life-threatening.
If you have diabetes, a ketones in urine test can help find high ketone levels early so you can get treatment right away. Home tests are available if your health care provider recommends frequent testing.
