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 helps if you have a history of weak immune function or you're being monitored for changes in cell-mediated immunity. The test looks at how well your immune cells recognize and react to a common challenge, giving insight into your body's defense capabilities.

What happens after I get my results?

Your results will be available in your account, with each value's normal range explained in simple terms. If your results show a weaker-than-expected immune response, next steps often include supporting your immune system through better sleep, nutrition, and stress management, and retesting after a few months to track change. The standard lab report can be downloaded directly from your account, and you can watch how your results shift over time using the trends feature. If a result is significantly abnormal, seeking medical care promptly is recommended.

Who should consider this test?

This test is a good fit for people who get sick often, take longer than usual to recover from infections, or have a condition that may affect their immune system. It's also useful for anyone wanting a baseline check of how well their immune cells respond to a known challenge. If you've had unexplained fatigue or repeated illnesses without a clear reason, this can offer helpful information.

What symptoms indicate I may need this test?
Common signs include getting infections more often than people around you, infections that take a long time to clear up, ongoing fatigue, or slow wound healing. Some people also notice they feel run-down more easily or catch colds that linger longer than expected. If these patterns sound familiar, this test can help clarify how your immune system is functioning.
How can I naturally support healthy immune function?
Getting enough quality sleep, eating a diet rich in fruits, vegetables, and lean protein, and staying physically active are some of the best ways to support your immune system naturally. Reducing chronic stress through activities like walking, meditation, or hobbies can also make a real difference, since stress hormones can dampen immune responses over time. Staying hydrated and limiting alcohol and processed foods rounds out a solid immune-supportive routine.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. Once processed, they'll be uploaded to your account where you can view them along with easy-to-understand explanations. You'll get a notification as soon as your report is ready to view.
What is cell-mediated immunity and why does it matter?
Cell-mediated immunity is the part of your immune system that uses specialized white blood cells, called lymphocytes, to directly fight off infections rather than relying on antibodies alone. It's your body's memory system for recognizing threats it has encountered before, like certain fungi or bacteria. When this system isn't working well, you may be more vulnerable to infections and slower to recover from illness.
What does a low or weak proliferation response mean?
A weak response means your lymphocytes aren't multiplying and reacting as strongly as expected when exposed to the test antigen. This can suggest your cell-mediated immune system isn't functioning at full strength, which may explain frequent infections or slow recovery. Simple steps like improving sleep, nutrition, and stress levels can help, but a significantly low result is worth discussing with a specialist promptly.
What can cause an abnormal immune response result?
Chronic stress, poor nutrition, certain medications, lack of sleep, and underlying health conditions can all affect how well your immune cells respond to a challenge. Age and certain long-term illnesses can also play a role in weakening cell-mediated immunity over time. Identifying and addressing these lifestyle factors can often help improve future results.
How often should I retest?
If your first result comes back normal and you have no ongoing symptoms, retesting once a year or as needed is usually sufficient. If you're actively working on improving immune function or managing a related condition, retesting every 3-6 months can help you track your progress. Use the trends feature in your account to see how your results change over time.

Candida-induced Lymphocyte Proliferation Response Stimulation Index 45
Demo results
Low Response (<60) Normal Response (60-180) High Response (>180)
Stimulation Index 45

What this means

Your lymphocyte response to candida antigen is lower than the normal range, suggesting your cell-mediated immune system may not be reacting as strongly as expected. This can mean your body is slower to recognize and respond to certain infections. It doesn't diagnose a specific condition on its own, but it's useful information about your overall immune function.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
