This test measures zinc inside your red blood cells rather than in the serum. Because red cells turn over slowly, RBC zinc reflects your zinc status over a longer window and is less affected by a recent meal or short-term fluctuation — a more stable view of your intracellular zinc.

Frequently Asked Questions

Do I need to fast?
No fasting is required.
How is this different from a regular zinc test?
Serum zinc reflects your level right now and can shift with meals, while RBC zinc reflects a longer window and is more stable — useful when you want a bigger-picture measure.
Is this billed to insurance?
No — you pay directly here, and nothing appears on your insurance record. Results go only to your secure account.
