Specialty Testing Q & A

What is specialty testing?

Specialty testing is a testing protocol designed to identify the underlying cause of a symptom, illness, or condition. Finding this information allows the doctor and the patient to treat their symptoms actively, instead of passively. With these tests, Dr. Preston can accurately and assuredly discover deficiencies, imbalances, and the root cause of the patient’s symptoms. Once she has discovered these issues, she can recommend the appropriate treatments.

What types of specialty testing are available?

Often there is a triad of genetics, infections or toxins, and stress that can affect disease progression. With most medical conditions, Dr. Preston often takes people off some or all of their unnecessary medications when she address and finds the underlying causes.

Dr. Preston uses these 7 tests as hidden causes of medical conditions:

1. Adrenal/Stress Testing

2. Viral, Bacterial or Fungal Infection Panel

3. Food Intolerance Testing

4. Heavy metal/Pesticides Load Testing

5. Genetic Testing

6. Nutrient/Antioxidant Testing

7. Leaky gut/Inflammatory Testing
