Skin & Ear Diagnostics

Skin and ear infections can look similar on the surface—but the right treatment depends on the exact cause. That’s where our in-house microscope comes in.

With microscopic cytology, we can identify infectious agents like:

  • Cocci bacteria
  • Rod bacteria
  • Yeast
  • Certain fungi

Whether your pet needs antibiotics or antifungal treatment, we always recommend cytology testing first to ensure precise and effective care. When needed, we send samples to our reference lab for more advanced analysis—and we always communicate clearly so you understand your pet’s diagnosis and treatment.

In-House Diagnostic Equipment In urgent situations, every moment counts. That’s why we’ve invested in top-tier in-house diagnostic tools, including: Blood Analyzer For red blood cell count, inflammation markers, liver/kidney health, and electrolyte balance. X-Rays To detect masses, bone issues, or foreign bodies. Ultrasound To view organs in greater detail when X-rays aren’t enough. Referrals When necessary, we partner with board-certified radiologists and cardiologists to ensure your pet receives the most informed care.

The most advanced diagnostic tools mean little without the right expertise. At Fullerton Pet Clinic, your pet’s diagnostics are reviewed by a doctor who knows their history and health journey. This ensures accurate interpretation in the context of their specific condition—not just numbers on a page. Whether it’s a wellness visit or an unexpected illness, we prioritize timely and reliable diagnostic results. Our goal is always to give you the answers you need—fast—so we can get your pet on the path to feeling better. Expert Interpretation
