A blood test analyzes a sample of blood to assess health, diagnose conditions, and monitor treatments. It measures various components like red and white blood cells, hormones, and proteins.
Anyone needing to diagnose health issues, monitor chronic conditions, or evaluate overall health may need a blood test. It’s also used for routine check-ups and assessing symptoms or risk factors.
Blood tests can identify potential health issues or
diseases early, often before symptoms appear, allowing for timely
treatment and better outcomes.
 
Blood tests reveal organ function, nutrient levels, and disease markers, helping doctors make informed decisions for diagnosis and treatment.
