Haemoglobin (Hb)

Haemoglobin is a protein in the blood, whose function is to carry oxygen, which is then delivered to the various body organs. Haemoglobin can fall (anaemia) in a number of conditions, especially where there is sudden blood loss; or chronic blood loss especially with a number of cancers. It can also fall with kidney disease, and in many malignant diseases. If the Haemoglobin is low before the operation, blood may have to be transfused.

Haemoglobin should be tested as a matter of course in male patients over 65 and female patients over 14.

Underlying Diseases/Conditions

Patients with renal disease, a bleeding disorder, or a malignancy should be tested for haemoglobin levels.

Current Drugs Use

Haemoglobin should be investigated in those patients who smoke, or are taking anticoagulants.
