What's this test for?

This test is ideal if you're checking whether your immune system responded properly to a pneumococcal vaccine. It's often used for people with a history of frequent infections, or for those being evaluated for a possible immune deficiency. It measures whether your body built enough protective antibodies against the bacteria that cause pneumococcal disease.

What happens after I get my results?

Your results will show up in your account, with each of the 23 serotype antibody levels explained alongside its normal range. If your levels look low, a simple next step is discussing retesting after a booster dose to confirm your body can mount a proper response over time. You can download the standard lab report anytime from your account, and use the trends feature to track antibody levels if you test again in the future. If any values are extremely low alongside signs of active infection, seek medical care right away.

What symptoms indicate I may need this test?

Frequent or unusually severe respiratory infections, recurring sinus infections, or repeated bouts of pneumonia can be signs your immune system isn't responding well to bacteria like pneumococcus. If you've had a pneumococcal vaccine and want to confirm it worked, that's another common reason to test. People with a family history of immune problems or unexplained recurrent infections often consider this test too.

How can I naturally support a healthy immune response?

Getting enough sleep, eating a balanced diet rich in fruits, vegetables, and protein, and managing stress all help your immune system function well. Regular moderate exercise and staying hydrated also support your body's ability to produce antibodies. Avoiding smoking and limiting alcohol can further help your immune system stay strong and responsive to vaccines.

When will I get my results?

Results are typically ready within about 7 days of your blood draw. You'll be notified as soon as your report is available in your account, where you can view each antibody level and what it means.

Who should consider this test?

This test is a good fit for people who've had frequent infections and want to check if their immune system responds normally to bacterial threats. It's also useful for anyone who received a pneumococcal vaccine and wants proof their body built protective antibodies. People being evaluated for possible immune deficiencies often use this test as part of understanding their overall immune health.

What is pneumococcal antibody testing and why does it matter?

This test measures IgG antibodies, which are proteins your immune system makes to fight off specific bacteria, in this case pneumococcus, a common cause of pneumonia and ear infections. By checking levels across 23 different serotypes (bacterial variants), the test shows how broadly and strongly your immune system can respond. This matters because a weak response could mean you're more vulnerable to serious infections and might need additional vaccination or follow-up testing.

What does a low antibody response mean?

A low or minimal increase in antibody levels after vaccination can suggest your immune system isn't building strong protection against certain pneumococcal strains. This doesn't automatically mean something is wrong, but it's worth noting if you get sick often. Simple next steps include retesting after a booster or discussing your infection history to see if further immune evaluation makes sense.

What causes a poor antibody response to vaccination?

Some people naturally produce fewer antibodies due to age, certain chronic health conditions, or underlying immune system differences. Certain medications that suppress the immune system can also lower antibody production. In many cases, a poor response is temporary and improves with a booster dose or over time as your immune system adjusts.

How often should I retest?

If your initial results show a weak response, retesting about 4-6 weeks after a booster vaccine is a common approach to see if antibody levels rise appropriately. If you're generally healthy and just confirming vaccine effectiveness, you likely won't need to retest unless you notice new patterns of frequent illness. Tracking your levels over time using the trends feature can help you spot any changes.
