The revolution in genetic diagnosis: how to reveal the secrets of disease through a drop of blood?
A revolution is quietly taking place in the medical field today. This is a new technology that no longer requires large-scale invasive examinations and integrates molecular diagnostic methods of genomics and proteomics. By analyzing biomarkers, these technologies can identify potential risk for disease and develop personalized treatments without drawing large amounts of body fluids.
Molecular diagnosis is a technology that combines molecular biology and medical testing. It can diagnose diseases, monitor conditions and develop the most appropriate treatment plan by accurately analyzing genes and the proteins they express.
Under the traditional medical model, the diagnosis and treatment of many diseases are often one-size-fits-all, but current new technologies make it possible for individual patients to receive customized medical plans. With the rapid development of molecular diagnostic technology, from the detection and prevention of infectious diseases to tumors, this technology is gradually changing the medical system.
History of Molecular Diagnostics
The boom in molecular biology began in the late 20th century and found its application in diagnostic medicine. In 1980, scientists first proposed a fetal genetic testing method that did not rely on DNA sequencing, thus beginning the exploration of genetic diagnosis. With the discovery of new genes and the advancement of DNA sequencing technology, molecular and genetic laboratory medicine has gradually become an independent discipline. In 2012, molecular diagnostic technology for thalassemia has become routinely used, demonstrating the commercial potential of molecular diagnostics.
As commercial applications grow in importance, the core issues of molecular diagnostics have also led to heated debate on patents for genetic discoveries—for example, the 2013 US Supreme Court decision that naturally occurring gene sequences cannot be patented.
Molecular diagnostic techniques
Molecular diagnostics have advanced rapidly from research tools to clinical practice. Advances in miniaturization technology have made it possible to move medical diagnostics into clinics, offices, and even homes. This requires ensuring that high reliability standards are followed and that medical testing complies with appropriate certification or medical device specifications.
In algorithm application, commonly used biological detection methods for molecular diagnosis include polymerase chain reaction (PCR) and its derivative technologies. Through these methods, detected marker molecules can be amplified for subsequent analysis. Because of the ability of molecular assays to detect sensitive markers, these tests are often more humane and less invasive for the patient than traditional biopsies.
Application of molecular diagnostics in different fields
Antenatal testing and disease risk management
Traditional prenatal testing methods rely on analyzing the number and appearance of chromosomes, while current molecular diagnostic methods can detect DNA at the molecular level, making the process more accurate and non-invasive. Early detection of genetic diseases such as Lynch syndrome can greatly improve clinical outcomes.
Cancer DiagnosisMolecular diagnosis of cancer allows doctors to select the best treatment options by analyzing the molecular fingerprint of cancer cells. Technological innovations have made it possible to detect DNA mutations through samples such as blood or urine, which not only reduces the pain of patients but also makes it possible to provide early warning of the disease.
Future diagnostic tools will likely focus on next-generation sequencing (NGS), which will improve the accuracy and efficiency of cancer detection through DNA and RNA sequencing.
Molecular diagnostic technology not only plays a brilliant role in clinical therapy, but also provides an important reference for disease screening and risk management. However, as these advances are made, we should also think about whether these breakthrough technologies can gain widespread acceptance and trust at the ethical, legal and social levels?
