Our Criteria For “Best” Blood Test Options

Test for Major Markers of Iron Deficiency:

We chose services which tested for levels of iron and total iron-binding capacity (TIBC), at a minimum. TIBIC analyzes how well iron combines with your blood.

If you are suffering from iron deficiency anemia, testing for these two blood markers is essential.

Certified Labs:

We chose blood test providers that were (Clinical Laboratory Improvement Amendments) CLIA-certified. Also, we also took into account their third-party reviews and standings with the Better Business Bureau.


We looked for websites that:

  • describe tests in detail
  • allow for easy scheduling
  • provide results quickly and in an easy-to-understand format
  • allow you to follow health trends as you order additional tests, and give quick results.
