What You Should Know About Allergy Testing Costs
Blood allergy tests (serum IgE panels) are convenient but have a 30-40% false positive rate. Intradermal skin testing (the gold standard) is more accurate but requires sedation and a veterinary dermatologist. If your vet did a blood panel for $275, the results are a starting point, not a definitive diagnosis.
Food allergy testing via blood panels is unreliable. The only accurate way to diagnose a food allergy is an 8-12 week elimination diet using a novel protein or hydrolyzed diet. If your vet charged $200+ for a food allergy blood panel, the results may not be meaningful.
After allergy testing, immunotherapy (allergy shots or sublingual drops) costs $200-$400 to start plus $50-$100/month ongoing. It takes 6-12 months to see full effect. About 70% of dogs improve significantly. The alternative is lifelong Apoquel ($2-$4/day) or Cytopoint injections ($75-$150 every 4-8 weeks).
