Routine blood tests have been a staple in preventive healthcare, providing insights into health markers like cholesterol and blood sugar. However, they often miss early disease indicators, leading to a false sense of security. According to Dr. Pawan Kumar Goyal, Senior Director of Internal Medicine at Fortis Hospital in Shalimar Bagh, these tests primarily identify established diseases rather than early risk factors. Factors such as broad 'normal ranges' and the inability to detect subtle changes contribute to this issue. To improve early detection, experts recommend monitoring trends over multiple tests, utilizing advanced biomarkers like high-sensitivity C-reactive protein (hs-CRP), and employing imaging tests for a clearer picture of organ health. Additionally, a thorough analysis of lifestyle and family history can help personalize risk assessments, enabling timely interventions for better health outcomes.
