How often should one get a blood test?

Regular blood tests are one of the simplest ways to detect hidden diseases in time. But how often should you do this to not miss something important - and not go overboard with anxiety?

For a healthy adult, it is recommended:

– Once a year to take a complete blood count (CBC) and biochemistry - this is sufficient for basic monitoring.

– If there are chronic diseases, risk factors (for example, obesity, heredity, stress) - once every 6 months.

For chronic diseases (such as diabetes, anemia, thyroid diseases, liver diseases):

– The doctor may recommend blood tests once every 3-6 months.

After COVID, flu, prolonged stress or infection - it is recommended to do at least a CBC to rule out hidden complications (such as inflammation or decreased immunity).

What a simple complete blood count can show:

Anemia (by hemoglobin)

Inflammation (by white blood cells and ESR)

Immune abnormalities

Signs of viral or bacterial infection

Important:

If you have complaints (weakness, dizziness, bruises, unusual pain) - don't wait a year, tests are needed immediately.

Conclusion: Even if you feel good, once a year - like a technical inspection for your body - is the mandatory minimum. It's cheap, fast, and can save your health.
