What's this test for?

This test is ideal if you're experiencing frequent infections, slow healing, or unexplained fatigue that suggests your immune system isn't responding the way it should. It's also useful if you've had a weakened immune system from illness, treatment, or a chronic condition and want to know how well your body's defense cells are working. The test checks how your immune cells react to common triggers, giving insight into your body's ability to fight off infections.

What happens after I get my results?

Your results will show up in your account with each value's normal range clearly explained so you know exactly where you stand. If your results suggest a weaker-than-expected immune response, simple next steps include improving sleep, reducing stress, eating a nutrient-rich diet, and retesting in a few months to track changes. A standard lab report is available for download anytime, and you can use the trends feature to watch how your immune response changes over time. If any result is significantly abnormal, seeking prompt medical care is recommended.

Who should consider this test?

This test is a good option for people with recurring infections, unexplained chronic fatigue, or a history of autoimmune or immune-related conditions. It's also useful for those who've been exposed to illnesses that suppress immune function and want a clearer picture of their body's defenses. Anyone curious about how well their immune memory is working after past infections or vaccinations may also benefit.

What symptoms indicate I may need this test?

Common signs include getting sick more often than usual, infections that take a long time to clear up, ongoing fatigue, or swollen glands that don't go away. Some people also notice slow wound healing or repeated skin issues. If these symptoms sound familiar, this test can help show whether your immune cells are responding normally.

How can I naturally support healthy immune cell function?

Getting consistent, quality sleep is one of the most powerful ways to support immune cell activity. Eating a diet rich in colorful vegetables, fruits, lean protein, and healthy fats gives your immune cells the nutrients they need to work well. Regular moderate exercise, stress management through activities like meditation or walking, and staying hydrated also help keep your immune responses strong.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. You'll get a notification once they're posted to your account, where you can view a clear breakdown of each measurement and what it means for your immune health.

What is cell-mediated immunity and why does it matter?

Cell-mediated immunity is the part of your immune system that uses specialized cells, called lymphocytes, to recognize and respond to threats like infections your body has encountered before. It's essentially your immune system's memory, helping your body respond faster the next time it faces a familiar germ. When this response is weak, you may get sick more often or take longer to recover.

What does a weak lymphocyte response mean?

A weak or low proliferative response means your immune cells aren't multiplying and responding as strongly as expected when exposed to a challenge, which can mean your immune memory or overall immune function is reduced. This can happen due to chronic illness, poor nutrition, high stress, aging, or certain treatments. Supporting your body with better sleep, nutrition, and reduced stress can help, but a significantly low result may need prompt medical follow-up.

How often should I retest?

If your first results are within a normal range and you feel healthy, retesting once a year or if new symptoms appear is generally enough. If you're actively working to improve immune function or recovering from an illness, retesting every 3-6 months can help you track progress and see if your changes are working.

What should I do if my results are abnormal?

Start by reviewing the explanation provided with your results to understand which part of your immune response may be affected. Simple lifestyle changes like improving sleep, nutrition, and stress levels are a good first step for mild abnormalities. If your results show a significantly weak immune response or you have ongoing symptoms, seek medical care promptly to explore the cause further.
