I’ve been feeling tired lately, and with the change of seasons, my skin has gotten worse. So, I decided to get a comprehensive medical check-up, which in Spanish is called an ‘Analítica Sanguínea,’ or a blood test. I’ve always gone through private insurance before, but this time I wanted to try the public system and share my experience as a guide for anyone who might find it useful.
Appointment and Process
You need a public health card (tarjeta sanitaria). Go directly to your assigned local health center (centro de salud) and make an appointment with your family doctor (médico de cabecera). During the appointment, explain your symptoms, for example, that you’re feeling tired or would like an annual check-up. The doctor will usually write a referral for a complete blood panel (Analítica Completa).
After getting the referral form, a nurse will give you a paper with instructions on where and when to go for the blood draw. It’s usually done early in the morning on an empty stomach, so you shouldn’t eat or drink anything after 10 PM the night before. The next day, just take the form to the designated location, wait in line, and get your blood drawn. The whole process is very quick and is over in just a few minutes.

Key Tests Included
Many people are probably curious about what specific tests are included. The basic check-up in the public system is actually quite comprehensive. I’ve compiled a list of the main tests the doctor ordered for me:
| Test Category | Specific Items |
| Complete Blood Count (CBC) | Red blood cells, white blood cells, platelets, hemoglobin, etc. Checks for signs of anemia or infection. |
| Basic Metabolic Panel | Glucose, uric acid, cholesterol, triglycerides. |
| Liver Function | Transaminases, to assess liver health. |
| Kidney Function | Creatinine, urea, to check the kidney’s filtering function. |
| Vitamins | Vitamin D, Vitamin B12, etc. Many people in Spain are deficient in Vitamin D despite the abundant sunshine. |
These are the most basic yet crucial indicators. If the doctor suspects other issues based on your condition, they might also add tests for thyroid function or specific hormones. I have to say, the public healthcare system is quite reliable in this regard, unlike some private providers that might order a bunch of unnecessary tests without a clear reason.
After the report is ready, your family doctor will send you a message to schedule another appointment to interpret the results in person. My results were mostly fine, just low on Vitamin D, so the doctor recommended getting more sun and taking supplements. The entire process, being part of the public system, was completely free. It’s a great benefit, as other procedures like the Antigen Test are also covered when necessary. For anyone with social security coverage, getting a regular check-up is highly recommended to detect potential health problems early. I hope my experience helps!
