Introduction
As we age, our bodies undergo various changes, making regular health check-ups crucial. Blood tests are an essential part of preventive healthcare, helping detect potential issues early and ensuring timely treatment. For seniors, certain blood tests are particularly important to monitor overall health, detect diseases, and manage chronic conditions effectively.
