I moved to Spain not long ago and was feeling a bit tired lately, so I went to my family doctor who ordered a full blood test (análisis de sangre) for me. I just downloaded the report online today, and staring at all the Spanish abbreviations and numbers made my head spin. After some research, I’ve finally figured out the basics, so I’m sharing what I’ve learned for anyone else who might be confused!
Understanding the Main Indicators
Blood test reports are usually divided into several major sections, with the most common being the Hemograma (Complete Blood Count) and Bioquímica (Biochemistry Panel). If you can understand these two, you’ll grasp about 80% of your report.
Hemograma (Complete Blood Count)
This section primarily looks at the quantity and state of various cells in your blood. It’s fundamental for identifying issues like infections or anemia. Here are some of the key metrics:
| Metric | English Meaning | What High/Low Levels Might Mean |
|---|
| Hematíes / Glóbulos Rojos | Red Blood Cells | Low levels may indicate anemia; high levels could be related to dehydration or blood disorders. |
| Hemoglobina | Hemoglobin | This is a key indicator for anemia, directly related to the blood’s oxygen-carrying capacity. |
| Leucocitos / Glóbulos Blancos | White Blood Cells | High levels usually suggest inflammation or an infection in the body. |
| Plaquetas | Platelets | Responsible for blood clotting. Low levels can lead to easy bleeding, while high levels increase the risk of thrombosis (blood clots). |
Next to these metrics, you’ll usually see a ‘Valores de Referencia’ (Reference Values) column or a range. If your results fall within this range, they are normal. My white blood cell count was slightly high, and the doctor said it was likely just a minor inflammation and advised me to drink more water and get plenty of rest.
Bioquímica (Biochemistry Panel)
The biochemistry panel is more complex. It measures the levels of various chemical substances in your blood, providing important information about your liver, kidneys, blood sugar, and lipid levels.
- Glucosa: This is crucial. High fasting blood sugar levels can be a warning sign for diabetes risk.
- Colesterol: This is divided into ‘good cholesterol’ (HDL) and ‘bad cholesterol’ (LDL). High LDL is a major culprit in cardiovascular disease, so you’ll need to adjust your diet quickly!
- Triglicéridos: Also a type of blood fat. High levels are also bad for your cardiovascular health.
- Urea / Creatinina: These two are key indicators for checking kidney function.
- Transaminasas (Transaminases): These are liver function indicators. If they are elevated, it might mean your liver is ‘tired’ and needs a break. In more serious cases, you should see a doctor to find out the cause.
Finally, a reminder for everyone: this guide is based on my personal research and understanding, and it cannot replace a professional medical diagnosis. After you get your report, if you find any metrics marked with an asterisk or that are significantly outside the normal range while checking your hospital report online, the best course of action is to make an appointment with your family doctor and get their professional opinion. I wish everyone good health!
