Blood Tests 

Why?

A low red blood cell count (anaemia) can affect the amount of oxygen reaching the balance part of the brain even when the blood pressure is normal. A low blood sugar level (hypoglycaemia) may also cause dizziness. Patients complaining of lightheadedness, a faint sensation or imbalance should therefore have a blood test to exclude anaemia.

How?

A blood sample is taken by the ENT Practice Nurse after the application of a rubber tourniquet to the upper arm. The samples are sent directly to the TDL laboratories for immediate analysis.
