Lately, I’ve been feeling a bit off, and with some recurring problems flaring up during the change of seasons, I decided to get my immune system thoroughly checked. Going through the whole process, I found that while Spain’s public healthcare system can be slow at times, it is indeed very meticulous. I’m writing down my experience as a reference for friends who might need it.
Booking an Appointment with a Family Doctor
Everything starts with the family doctor. I booked an appointment with my GP directly through a mobile app, explaining that I’ve been feeling persistently fatigued, experiencing occasional low-grade fevers, and having some skin issues. The doctor listened patiently and, instead of just prescribing medication, suggested a comprehensive blood analysis. He wrote me a referral to the hospital’s immunology department for further examination. The whole process was very smooth. Family doctors act as the “gatekeepers” of the public healthcare system, so it’s always right to consult them first for any health concerns.

The Process for Seeing a Specialist
With the referral from my family doctor, I received a call from the hospital to schedule an appointment with an immunologist. The wait was about a month, which is considered normal for the public system. The specialist once again asked detailed questions about my condition and family medical history, then ordered a series of more specific blood tests, mainly targeting various autoimmune antibodies, complements, immunoglobulins, and so on. The blood draw was done right there in the hospital, which was very convenient. I have to say, the specialist’s level of professionalism was much higher, asking very specific questions that made me feel reassured.
After the test results came back, the doctor called me for another consultation. He went through the pile of reports, explaining the meaning of each indicator to me one by one. Fortunately, my results were mostly within the normal range, ruling out several autoimmune diseases I was worried about. The doctor explained that my current symptoms are more likely due to temporary immune dysfunction caused by stress and seasonal changes. He recommended adjusting my lifestyle, improving my diet, and getting more exercise. I quite appreciate this approach of finding the root cause rather than just ‘treating the symptom.’ Here are some of the main tests I had, to give you an idea:
| Test Category | Specific Tests |
| General Blood Work | Hemograma completo, VSG, PCR |
| Autoantibodies | ANA, Anti-DNA, Factor Reumatoide |
| Immunoglobulins | IgG, IgA, IgM, IgE |
| Complement System | C3, C4 |
My experience with the Spanish healthcare system for this immunology visit was quite positive. Although the wait was a bit long, the examination was comprehensive and thorough. Most importantly, the entire process, including all the lab tests, was completely free of charge. If you have similar issues or if your family doctor recommends it, don’t hesitate to see a specialist just because it seems like a hassle. Sometimes, getting to the bottom of a problem is the only way to get true peace of mind.
