In both dogs and cats, routine haematology, biochemistry and urinalysis should be performed. Most parameters are usually within normal limits, but an anaemia can often be seen. Eosinophilia and basophilia are also common, and when seen together suggests occult dirofilariasis or allergic lung disease ^{1, 3}. Eosinophilia peaks as L5 enter the pulmonary arteries and subsequently varies. An inflammatory leukogram is also possible³. Hyperglobulinemia due to antigenic stimulation is an inconsistent finding^{1, 3}. Right-sided heart failure or immune-complex glomerulonephritis can lead to hypoalbuminaemia and, very occasionally, nephrotic syndrome¹. Because of this, it is possible for urinalysis to reveal proteiunuria^{1, 3}. Haemoglobinaemia and haemoglobinuria are associated with caval syndrome³.
