Before you order

Does the price include a visit or personal lab review?

No. These prices cover testing and the fees listed above. A visit, personal review, and treatment plan are separate services.

Can I order more than one blood panel?

The blood panels share many of the same tests. Check the included lists with your care team to avoid paying for repeat tests.

Do I need to fast or time my samples?

Follow the instructions Fullscript sends for your test. Some panels need fasting or a morning draw. Hormone tests may need timing around your cycle or medicines. Ask your care team before changing any medicine.

Where do I check the latest price and availability?

Fullscript shows the current price and ordering details. Review them before you pay. Test options and collection steps can vary by location.

Tests are offered through the Root Causes Clinic Fullscript store. Choose tests with your care team; results need to be read in the context of your health history.
