Urine is often submitted for microbiological evaluation when investigating lower urinary tract disease in cats and dogs. In these cases, culture should always be accompanied by a complete urinalysis including a urinary sediment examination, and ideally should only be performed on a cystocentesis sample.

SVS Laboratories has recently purchased the Siemens Hematek 3000 semiautomated slide staining system to improve efficiency and staining quality.

Semiautomated stainers stain the middle portion of the upper side of a glass slide, and a blood film or cytology smear prepared outside this area is not stained (see below). The unstained area starts about 13mm from the edge of the glass slide, therefore, we recommend blood films and cytology preparations are made within the staining area.

Diff Quik (DQ) stains are commonly used in practice to examine blood smears and cytology samples. It is a three-step system using methanol as a fixative followed by an orange/eosinophilic solution then a blue/basophilic solution. Note that samples should not be stained until they are completely dry.

Hyperaldosteronism is an adrenal disorder in which there is excessive aldosterone secretion. It may be caused by autonomous adrenal secretion (primary hyperaldosteronism) or to diseases that lead to increased aldosterone levels (secondary hyperaldosteronism). Primary hyperaldosteronism (PHA) occurs secondary to the growth of a benign or malignant adrenal tumour or to hyperplasia of the adrenal zona glomerulosa. PHA is considered the most common adrenal disorder of cats and is most often due to a unilateral adrenocortical carcinoma.
