Understanding the Blood Tests in a Full Body Checkup

Blood tests provide vital information about how your body is functioning internally and can reveal hidden conditions before symptoms appear.

They play a crucial role in preventive healthcare, helping doctors recommend lifestyle changes or further investigations if needed.
