The DDxHub System (Differential Diagnosis Hub) is a clinical decision support tool that helps healthcare professionals link patient symptoms with relevant lab tests to narrow down potential diagnoses.
Here's how it works:

How DDxHub Links Symptoms with Lab Tests:
Symptom Input:

Users input patient symptoms (e.g., fever, fatigue, abdominal pain).

Differential Diagnosis Generation:

The system generates a list of possible conditions based on the symptoms.

Lab Test Recommendations:

Suggests specific lab tests to confirm or rule out diagnoses (e.g., CBC for infection, TSH for thyroid issues).

Result Interpretation:

Helps interpret lab results in the context of symptoms to refine the diagnosis.

Dynamic Updates:

Continuously updates the list of potential diagnoses as new lab results or symptoms are added.

Example:
Symptoms: Fatigue, weight gain, cold intolerance.

Potential Conditions: Hypothyroidism, anemia, depression.

Recommended Lab Tests: TSH, Free T4, CBC, Iron studies.

Diagnosis: Based on lab results (e.g., elevated TSH confirms hypothyroidism).

Benefits:
Improves diagnostic accuracy.

Saves time by prioritizing relevant tests.

Reduces unnecessary testing.

This system is particularly useful in complex cases where symptoms overlap across multiple conditions.
