No labs match that search. Try another name, or ask us at your visit.

Lab Results Frequently Asked Questions
Answers to Common Questions About Your Labs
Why doesn’t this guide list normal ranges?
Each lab uses its own reference range, printed on your report. Learn what “normal range” really means.
My results are “normal” but I still feel off. Why?
Normal ranges are wide, and normal isn’t always optimal for you. Read Can You Have Hormone Symptoms With “Normal” Labs?
Can you review labs I had done elsewhere?
Yes. Bring recent results to your visit and Allana will go over them with your symptoms and history.
Should I fast before my blood draw?
For tests like fasting insulin, glucose and a lipid panel, usually yes, often 8–12 hours. Your provider will tell you what your tests need.
