Hyperthyroidism is the most frequent endocrinopathy in cats and its routine screening is recommended for senior and geriatric cats. Immunoassays that are rapid, cheap and reliable are therefore needed.
The aim of this study was to evaluate a new point-of-care using a new technology called Surface Plasmon enhanced Fluorescence method (SPF) for the measurement of total thyroxine (tT4) in feline samples.
SPF detects fluorescence and measures the quantity of substances by intensely exciting, with the near-field light generated surface plasmon resonance (SPR), fluorescent substances that exist near the metal surface.
