Treating the cause, not the symptoms

Finding the best treatment for each patient isn’t always straightforward. Sometimes there are multiple factors that contribute to a condition. Other times a single underlying cause leads to symptoms across various body systems. Plus, how a disease or cause manifests in each patient varies based on factors like genes, hormonal changes, environment, diet, and other lifestyle components. That’s why at Quest, we offer both routine and comprehensive testing to fully understand a patient's health status.

For example, inflammation has been identified as an underlying cause for conditions in all areas of medicine. However, these diseases are often treated separately by specialists with a focus on alleviating symptoms. An approach that addresses the root cause of chronic inflammation, whether it be exposure to toxins or hormonal imbalance, can lead to lasting improvements in patient health beyond symptom suppression. Inflammatory markers and other specialty testing may be considered when determining the best care path for a particular patient.
