Lab Results Reference Tool
Compare selected values with broad educational intervals. This tool does not diagnose conditions or interpret patterns; use the interval on your report and your clinician's guidance.
How do I understand my blood test results?
Use the reference interval printed on your own report first. The tool below offers broad educational comparisons for selected CBC, metabolic, lipid, thyroid, and iron values, but does not diagnose conditions or interpret combinations of results.
Panels We Cover
- CBC — Complete Blood Count (WBC, RBC, hemoglobin, platelets)
- CMP — Complete Metabolic Panel (glucose, kidney, liver)
- Lipid — Cholesterol panel (total, LDL, HDL, triglycerides)
- Thyroid — TSH, Free T4, Free T3
- Iron — Serum iron, ferritin, TIBC, transferrin saturation
How to Use This Tool
- Find your lab report (printed or in your patient portal)
- Select the panel type (CBC, CMP, etc.)
- Enter each value from your report
- Compare the result with the interval on your report
- Discuss questions with the clinician who ordered the test

Frequently Asked Questions
Are these reference ranges accurate?
They are broad educational examples, not your laboratory's validated intervals. Ranges vary by laboratory method, age, sex, pregnancy, medication, and clinical context. Always use the interval printed on your report.
What does an abnormal result mean?
An out-of-range result doesn't necessarily mean something is wrong. Many factors can temporarily affect results, including diet, exercise, medications, and hydration. Your doctor considers the full picture.
Should I be worried about a "critical" value?
Do not use this tool to determine urgency. Follow any instructions on the report and contact the clinician who ordered the test if a result is marked critical or you are unsure what to do next.
Where can I find my lab results?
Check the patient portal used by the ordering provider or laboratory, or contact them for a copy. Release timing and portal availability vary.
