How to use this list
The tests below are a reference list. Whether a test is useful for you depends on your symptoms, your family history and any conditions you already have, so not every test applies to every person.
A doctor can advise whether and how often to test, and can explain what a result means for you.
Preparing for the tests
In the Zavis test directory, Lipid Panel and Testosterone are listed as needing fasting. CBC, HbA1c, LFT, KFT, TSH, Vitamin D, PSA and CRP are listed as not needing it. Ask the lab how to prepare if you are unsure.
Finding a lab
15 labs are listed in the Zavis lab section. 11 of them say in their profiles that they offer home sample collection, where a nurse or phlebotomist visits to take the sample. Ask the lab whether it offers the tests you need before you book.
