If a general anaesthetic is to be given, you will also be asked if you would like a blood test done beforehand. Of course, all animals undergoing an anaesthetic will have a full examination beforehand, but sometimes there are hidden problems which an examination does not reveal. This blood test looks at various organ systems which are particularly relevant to anaesthesia, such as the state of the kidneys and liver, and cell counts. It is not a full blood panel, and a clear result is not a guarantee either that there are no internal problems, nor that the anaesthetic will be completely safe, but it sometimes gives us useful guidance, particularly in older pets. In younger, apparently healthy animals, the results are usually normal, but even in these patients we occasionally find unexpected problems.
