What's this test for?

This test is ideal if you're experiencing unexplained inflammation, recurring infections, or digestive issues that won't resolve. It helps doctors evaluate your immune system function and can detect certain blood disorders or leukemias. Many people use this test when they have persistent health issues that suggest immune system problems or when monitoring treatment for blood-related conditions.

How should I prepare for this test?

No fasting is required for this test. You can eat and drink normally before your blood draw. Simply visit your chosen lab location during operating hours, and the blood sample will be collected through a standard venous draw.

What's included in this test?

Lysozyme

This test measures lysozyme, an enzyme in your blood that reflects the activity and breakdown of immune cells called granulocytes and monocytes. Elevated levels can indicate inflammation, immune system activation, or certain blood cancers like leukemia, while low levels may suggest weakened immune function. This biomarker provides important insights into underlying inflammatory conditions, digestive problems, and how well your immune system is performing.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your lysozyme levels mean for your immune health and inflammation status. These notes include personalized recommendations like dietary changes, immune-supporting supplements, or whether you should follow up with a specialist for further evaluation. You'll also get the standard lab report and can track your lysozyme levels over time using our trends feature, which is especially helpful if you're monitoring a chronic condition or treatment progress.
Who should consider getting this test?
This test is useful for people with unexplained inflammation, recurring infections, or persistent digestive issues. It's also important for those being evaluated for blood disorders or leukemia, anyone with a family history of blood cancers, and patients already diagnosed with leukemia who need to monitor treatment effectiveness. Your doctor may order this if standard inflammation markers don't explain your symptoms.
What symptoms indicate I may need this test?
Common symptoms include unexplained fevers, night sweats, chronic digestive discomfort, frequent infections, unexplained weight loss, or persistent fatigue. You might also experience swollen lymph nodes, easy bruising, or feeling generally unwell without a clear cause. These symptoms could indicate immune system issues or inflammatory processes that this test can help identify.
How can I naturally support my immune system?
Supporting immune health starts with eating a nutrient-rich diet full of colorful vegetables, fruits, lean proteins, and healthy fats. Getting 7-9 hours of quality sleep, managing stress through meditation or yoga, and exercising regularly all strengthen immune function. Avoid smoking, limit alcohol, stay hydrated, and consider probiotic-rich foods like yogurt to support gut health, which is closely linked to immune performance.
What is lysozyme and why does it matter?
Lysozyme is an enzyme produced by your immune cells that helps break down bacteria and fight infections. It's found throughout your body, including in tears, saliva, and blood. Measuring lysozyme in your blood helps doctors understand immune cell turnover and activity, making it valuable for diagnosing inflammatory conditions, certain cancers, and monitoring how well treatments are working.
What does high lysozyme mean?
High lysozyme levels typically indicate increased breakdown of immune cells, which can occur with certain types of leukemia (especially monocytic or granulocytic leukemia), tuberculosis, sarcoidosis, or other inflammatory conditions. Elevated levels aren't always serious but warrant further investigation to determine the underlying cause. Your doctor will interpret results based on your symptoms and medical history.
What does low lysozyme mean?
Low lysozyme levels may occur in people with lymphocytic leukemia or conditions that reduce the number or function of granulocytes and monocytes. It can indicate weakened immune function or reduced immune cell production. Low levels are less common than high levels but should be evaluated alongside other blood tests and your overall health picture.

What this means

Your lysozyme level is elevated above the optimal range, which indicates increased immune cell turnover. This can occur with inflammation, certain infections, or blood disorders, and warrants follow-up to identify the underlying cause.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
