How to Check Biomarker Ranges with ChatGPT
Check biomarker reference ranges with ChatGPT and ToolRouter.
Tool
ChatGPT presents biomarker reference ranges in clear tables and written explanations, making it easy to study multiple related markers together, build quick-reference guides, or prepare educational content about specific lab panels.

Steps
Once connected (see setup above), use the Lab Results tool:
- Ask: "Look up reference ranges for thyroid markers T3, T4, and TSH using lab-results"
- ChatGPT returns ranges, units, and clinical significance for each
- Request: "Format these as a study reference table"
- Follow up: "Which of these should I check first when assessing thyroid function?"
Example Prompt
Try this with ChatGPT using the Lab Results tool
Look up reference ranges for the complete hepatic function panel markers using lab-results — ALT, AST, ALP, GGT, bilirubin, albumin. Present as a reference table and explain what each marker tells us about liver health.
Tips
- Ask for a complete panel together rather than individual markers for a systematic reference
- Request methodology-specific notes — some ranges differ significantly between assay types
- Ask for clinically significant thresholds alongside normal reference ranges for context
