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 recurring infections or suspected immune deficiencies who need to confirm their body can build protective antibodies. It's also useful if you or someone monitoring your health wants proof of adequate vaccine response before or after treatment.

What's included in this test?

This test measures your immune system's antibody response to 13 different strains, or serotypes, of Streptococcus pneumoniae bacteria. Checking multiple serotypes matters because your immune system may respond well to some strains but not others, giving a fuller picture of how well-protected you are against pneumococcal infection.

What happens after I get my results?

Your results will show up in your account with each of the 13 serotype antibody levels explained alongside their normal reference ranges. If your levels are low, a simple next step is discussing revaccination timing or retesting in a few weeks to see if levels rise appropriately. You can download the standard lab report directly from your account, and if you test again in the future you can track your antibody trends over time to see how your immune response changes.

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 produce antibodies effectively. Staying active and avoiding smoking can also support better vaccine response over time. If you're concerned about a weak immune response, keeping up with a consistent sleep schedule and reducing alcohol intake are simple habits that can help.

When will I get my results?

Results are typically ready within about 7 days after your sample is collected at the lab. You'll receive a notification once your report is available in your account so you can review each antibody level right away.

Who should consider this test?

This test is a good fit for people with a history of frequent or unusual infections, those with suspected immune system issues, and anyone who needs to confirm their body responded well to a pneumococcal vaccine. It's also useful for people undergoing treatments that can affect immune function and who want to check their protection status.

What symptoms indicate I may need this test?

Frequent respiratory infections, repeated pneumonia, sinus infections that keep coming back, or being diagnosed with an immune deficiency are common reasons to consider this test. If you've noticed you get sick more often or more severely than people around you, it may be worth checking your antibody response. Unexplained fatigue tied to ongoing infections can also be a signal worth investigating.

What is a pneumococcal antibody test and why does it matter?

This test looks at whether your immune system created enough protective antibodies after exposure to a pneumococcal vaccine. It matters because having low antibody levels across multiple serotypes can mean your body isn't building strong defenses against a common cause of pneumonia, sinus infections, and ear infections. Knowing your antibody status helps guide decisions about revaccination or further immune evaluation.

What does it mean if my antibody levels are low?

Low antibody levels across several serotypes can suggest your immune system isn't responding strongly to vaccination, which may leave you more vulnerable to pneumococcal infections. This doesn't always mean something is seriously wrong — some people naturally respond more slowly and may show improvement on a repeat test. If levels stay low after retesting, it's worth exploring further with an in-depth immune evaluation.

How often should I retest?

A common approach is to retest 4 to 6 weeks after a vaccine dose to see how much your antibody levels rose compared to before. If you have ongoing concerns about immune function, retesting every year or as advised based on your health history can help you track changes. Tracking results over time in your account makes it easy to see your trend at a glance.
