There
are numerous tests and diagnostic aids that can be used to help
us discover what is wrong with our patients. The kinds of tests
used depend on what symptoms the animal displays.
Initial
screening tests often involve urine and faeces samples which can
be analysed in our "in house" laboratory. Much useful information
can be gained from these simple tests. For example, certain infections,
parasites and metabolic problems can be detected.
Blood
samples are usually our next line of investigation. These are taken
from veins in either the foreleg or neck of cats and dogs. We analyse
the blood cells and also certain chemicals present in the fluid
portion. These results can give us an insight into certain infections
and also give us an overview of the state of particular internal
organs. In
some cases this may lead us to do further, more specific blood tests,
which are sent away to external laboratories for analysis.
In
many disease conditions it is also helpful for us to try and visualise
particular areas of the body. This is called "diagnostic imaging"
and includes x–rays and ultrasound scanning. Both these techniques
are non–invasive and non–painful, though animals may require sedation
or anaesthesia in order that we may perform the procedures. They
enable us to take an "indirect look" at the internal organs.
Another
very useful technique is endoscopy. This is unique in that it enables
us to visualise lesions directly. It is usually used for investigations
of the respiratory and gastrointestinal tract. The patient is anaesthetised
and a flexible tube containing optic fibres passed into the appropriate
position. It is also possible to take small biopsies via a tiny
pincer–like arm which is incorporated into the equipment.
For
heart problems it may be necessary to take an electrocardiograph.
Wires are attached to each of the patient's limbs which read the
electrical impulses across the heart. These are then turned into
a graph which is traced out onto paper. It gives an impression of
the rate and rhythm of the heart as well as giving an idea of the
size of the heart chambers.
An
extremely wide range of tests and facilities are available for investigation,
monitoring and treatment of different medical conditions. Every
case is unique and so the number and type of tests used are specially
tailored to the individual patient's needs. The aim is for an efficient
and accurate diagnosis, so enabling a speedy recovery for your pet.
