Biopsy and Histopathology

Animal doctor provides biopsy/histopathology services for abnormal tissue. We accept referrals and provide second opinions.

Description: A biopsy is a common diagnostic tool used to evaluate the skin or other organs as it gives a good insight to the architecture of the cellular level for the area of interest. Biopsy results (histopathology) can differentiate between infections, allergic skin disease, autoimmune conditions, and tumors (benign v. malignant).

Symptoms & What to look for: Abnormal growth or non-healing wounds are the most common signalment for biopsy.
