What is analysed? Beta-amyloid 42 (Aß42) and tau protein are two biomarkers found in cerebrospinal fluid (CSF) associated with the development of Alzheimer's disease. Aß42 is a peptide, while tau protein is a structural brain protein. The Aß42 and tau protein test measures the concentration of Aß42 and tau protein in CSF. What does the result

What is analysed?Bicarbonate and CO₂ are chemical compounds: Bicarbonate helps maintain the pH balance in the blood and CO₂ (carbon dioxide) is exchanged for oxygen during the gas exchange process.The Bicarbonate and CO₂ test measures the levels of bicarbonate ions and CO₂ in the blood.What does the result mean?The result indicates the concentration of bicarbonate ions and CO₂ in the blood.Why con

What is a bicuspid aortic valve? A bicuspid aortic valve (BAV) is a heart defect that is present at birth (congenital), which affects the aortic valve. The aortic valve is a valve in the heart where the left ventricle (lower chamber of the heart) meets the aorta (the body’s largest artery, which carries blood out of the heart to the rest of the body).

What is biofeedback?   Biofeedback is based on the idea that by becoming more aware of your body and the processes going on within it, you can actually control some of those processes. It involves using instruments that provide information on the various systems in your body, such as EMGs, thermometers and electroencephalographs to teach the patient how to control such things as their b

What is biological therapy? Biological therapy involves using living organisms or substances derived from living organisms in the treatment of diseases, in particular cancer. The treatment consists of using the body’s immune system to act against and destroy cancer cells. The therapy is used to treat numerous types of cancer by slowing down the growth of tumours and preventing the

What are biomarkers?   In medicine, biomarkers are biological substances that provide a measurable indicator of: The disease or condition someone has How the body is responding to a treatment, including medication The chances of developing a condition or responding to treatment in the future     Biomarkers are fundamental in all areas of medicine.
