The team aims to investigate the use of
novel markers that could help differentiate
neoplastic from non-neoplastic causes
of PE. For example, the measurement of
lactate dehydrogenase in both serum and
PE samples has been evaluated in cases of
PE in humans. Lactate dehydrogenase has
been evaluated in healthy dogs and dogs
with various types of cancer and further
work is needed to determine if this could be
a useful test in dogs with PE.
