  "account": "Chemical signatures or biomarkers are being researched to enhance the diagnosis of various diseases, particularly those impacting the brain and nervous system. However, establishing the meaning of these changes and their reliability in pinpointing specific conditions, as well as ensuring patients' access to the tests, remains a challenge. As more biomarkers bind to antibodies, increased impedance is measured, which is what is being monitored.",
  "summary": "Tests that can detect changes in proteins and other molecules in the body could help doctors identify diseases such as Alzheimer’s earlier. However, experts call for better affordability and accuracy of such tests for patients across India",
