Dermatological Diagnosis and Diagnostics
Diagnosis is the identification of a condition or disease, suffering a patient, diagnosed by systematic analysis of the background history and further investigation of the assumed or probable causes. Effective prognosis is not possible without effective diagnosis. There are various diagnostic tests that can be performed "in house" by veterinarians to help with everyday dermatological cases. A dull scalpel blade or similar instrument is moistened with mineral oil and used to scrape away some of the epidermis, in which may reside a number of different parasites. A trichogram is used to visualize the hair for evidence of pruritus (self- inflicted alopecia), dermatophytosis, endocrine alopecia, pigmentation defects, and growth phase. For Allergy Testing Atopic Dermatitis – Intradermal testing (IDT, IDST) and aeroallergen-specific IgE serum testing (ASIST, in vitro testing) are considered important tests for the demonstration of IgE-mediated hypersensitivity in atopic dogs.
