In order to provide an accurate diagnosis, on many occasions, additional tests are needed. These could be blood tests, imaging tests as well as audiological examination. Some of the most common tests are:
RAST allergy test (IgE Blood test)
This is a blood test to determine the specific substance someone is allergic to. Results are usually available in 1-2 working days.
Skin prick allergy test
During this test the patient's skin is pricked with a small needle or pin, which contains a small amount of allergen. Depending on the skin reaction, it is defined whether or not there is an allergy as well as its degree.
CT (Computerized Tomography) scan of the sinuses
This is a diagnostic test, similar to the X-Ray that produces images of the paranasal sinuses, which are connected to the nasal cavity by small openings. It is used for the diagnosis of inflammation, sinusitis, presence of polyps, tumours as well as an evaluation of fluid in the sinuses.
MRI (Magnetic Reasonance Imaging) scan of the head
This imaging test uses magnets and radio waves in order to produce images of the brain and the surrounding nerves. This tests causes no pain. However, due to the use of strong magnets all metal objects are prohibited. These objects could be removable dental work, hearing aids, jewellery, credit cards, pins etc.
Pure Tone Audiogram
An audiogram is a graphical representation of a patient's hearing levels. It shows the softest sounds someone can hear at different frequencies.
This test is used to examine the condition of the middle ear, eardrum and the conduction bones. This happens by creating variations of air pressure to the ear canal. It is used to diagnose otitis media, perforated ear drum etc.
Full Vestibular Assessment
A sleep study, also known as a polysomnogram, is often requested by the doctor when more conclusive evidence is required to confirm a sleep disorder or to make a diagnosis such as obstructive sleep apnoea. Overnight stay at a hospital or sleep centre may be required to carry out sleep studies. During the sleep study information including brain activity, eye movement, heart rate, blood pressure and oxygen levels are measured and recorded. The data collected is then passed to the doctor for interpretation, diagnosis and treatment plan.
After a final diagnosis is made a treatment plan is provided depending on the condition. We aim to provide patients with as many details as possible regarding their condition and treatment plan and we do aim at invlving them in the decision making process. For effective treatment, follow up appointments might be necessary until the symptoms resolve.
