Don’t let immunodeficiencies stand between you and good health
Your immune system is what keeps you from getting sick. When this main line of defense isn’t working properly, it can lead to infections, diseases and even autoimmune disorders. Once you know for certain whether your immune system is compromised, you can take steps to ensure a return to good health. We recommend our immune health lab tests for accurate information. Most tests don’t require fasting.
What does an immunity lab test look for?
- An immunodeficiency
- Whether you have a balanced number of immunoglobulins (antibodies) and other immune cells
- Proper function and interaction between proteins and cells
