Squeeze Tape Impressions: An Alternative Diagnostic Test for Demodex


 

I suspect I am not the first veterinarian to declare that I loathe performing deep skin scrapings. To take an already inflamed area of skin, and scrape it repeatedly with a scalpel until the point of capillary oozing, is not typically a comfortable experience for the animal, and is therefore one of the more unpleasant procedures to perform on a patient without anaesthesia. So to discover the Squeeze Tape Impression is an alternative,  sensitive and reliable method for diagnosis of demodex[1], which may be performed with little or no discomfort to the patient, is a revelation.

While surgery and E/CC medicine tend to steal the limelight when it comes to lifesaving procedures, the value of being able to accurately diagnose insidious skin diseases like demodex cannot be underestimated, given the dramatic consequences for the animal’s health and quality of life. Consequently, the Squeeze Tape Impression is a wonderful technique for vets in general practice to learn and apply, particularly as a simple, non-invasive ‘rule-out’ test – when the index of suspicion is low – so that these cases are not mis-diagnosed.
