Blood disorders

Blood is made up of liquids (called plasma) and solids consisting of red and white blood cells and platelets.

Disruption of the plasma, cells or platelets affects blood function. Blood disorders can be inherited, or caused by other problems like lack of nutrients in the diet (anaemia) and cancers (leukaemia). Follow the links below to find trusted information about blood disorders.

Anaemia - Lab Tests Online AU

Anaemia is a condition that occurs when the number of red blood cells (RBCs) and/or the amount of haemoglobin found in the red blood cells drops below normal. Red blood cells and the haemoglobin contained within them are necessary for the transport and delivery of oxygen from the lungs to the rest of the body. Without a sufficient supply of oxygen, many tissues and organs throughout the body can be adversely affected. Anaemia can be mild, moderate or severe depending on the extent to which the RBC count and/or haemoglobin levels are decreased. It is a fairly common condition, affecting both men and women of all ages, races and ethnic groups. However, certain people are at an increased risk of developing anaemia. These include people with diets poor in iron and vitamins, chronic diseases such as kidney disease, diabetes, cancer, inflammatory bowel disease, a family history of inherited anaemia, chronic infections such as tuberculosis or HIV, and those who have had significant blood loss from injury or surgery.
