Given the history of low immunity counts, a poor vaccine response, and recurring infections over the years, these are exactly the kinds of signs that doctors look at when evaluating for PI. A weak or absent antibody response after vaccination is actually one of the key indicators that something may be off with how the immune system makes antibodies.

Genetic testing can be a valuable tool in this situation. Here's why it might be worth discussing with a doctor or immunologist:

- It can confirm or rule out a specific PI diagnosis
- It can help identify the exact gene change involved
- It can influence and improve the treatment plan — one study found that treatment plans changed for 35% of people with PI who had genetic testing
- It can provide clarity when other test results are inconclusive That said, genetic testing isn't perfect. It can be expensive, and not every type of PI has a known genetic cause, so it doesn't always provide answers for everyone.

The best next step would be to speak with an immunologist — a specialist in immune deficiencies — who can review the full picture and advise whether genetic testing makes sense. It's absolutely worth bringing up this history of recurring infections and the poor vaccine response at that appointment.
