It is very important to monitor blood pressure when animals suffer from certain diseases. Common diseases that can result in high blood pressure (hypertension) include kidney disease and a hormonal disease called Cushing’s disease or hyperadrenocorticism. Untreated hypertension can be very harmful and can result in organ failure or blindness. Haematology and Biochemistry Haematology and biochemistry are blood tests that are carried out frequently in veterinary practice. Haematology refers to the assessment of the levels and appearance of red blood cells (cells that carry oxygen around the body), white blood cells (important cells of the immune system) and platelets (cells that that help stop bleeding) in the blood. The biochemistry tests analyses the other products found in blood, such as proteins and waste products. Haematology and biochemistry tests are excellent health screening tools and can give vital information about many diseases such as infectious diseases, anaemia, kidney or liver disease, and even some cancers such as lymphoma or leukaemia. These tests can often pick up early signs of disease and is why there are offered as health screening tests, especially as animals start to age. Treating diseases as early as possible often gives the best chance of cure or successful management. To get the most information out of these tests, a urine sample will often be submitted for analysis too.
