💡 Problem Description

Some users may not be familiar with medical terms like HDL, TSH, Normal Range, etc. This can make it hard for them to understand their health reports.

---

✅ Proposed Solution

Add a Help Tooltip or Info Panel beside key column headers in the results table.

• A small ℹ icon will appear next to headers (e.g., Normal Range).
• On hover or click, it will show a tooltip with a short explanation.
• Example: “Values outside this range may indicate abnormal test results. Please consult a doctor.”

---

🔄 Alternatives Considered

• Adding a separate glossary page (too heavy for a small enhancement).
• Adding footnotes under the table (clutters UI).

---

📘 Additional Context

This feature improves usability and learning, especially for non-medical users, while keeping the UI clean.
