introduction
During the COVID-19 pandemic, healthcare systems around the world are facing unprecedented challenges, especially when it comes to diagnosing infections quickly and accurately. Traditional viral testing methods, such as polymerase chain reaction (PCR) tests, are highly accurate, but require specialized laboratory equipment and long processing times, which are strained in the context of the rapid spread of the epidemic. In the face of this challenge, the development and application of home molecular testing technology has risen rapidly as part of the public health response. Home molecular testing techniques, especially those based on isothermal nucleic acid amplification (e.g., LAMP technology), provide a new self-testing option for the general public due to their rapidity, portability, and ease of operation. Users can complete sample collection and testing at home with a simple operation, which greatly shortens the time from sampling to getting results, making early detection and early isolation possible. With the advancement of science and technology and the improvement of people's health awareness, molecular diagnostic technology has gradually entered ordinary families from the professional field of laboratories. Home molecular testing is not limited to COVID-19, but is gradually expanding to rapid detection of other diseases, including influenza, sexually transmitted diseases (STIs), and various respiratory diseases. This shift from the lab to the home marks a new era in personal health management and disease prevention. Through at-home molecular testing, individuals can more proactively and conveniently manage their health status, stay informed about the risk of infection, and seek medical help if necessary, thereby improving the overall level of personal health and public health. While home molecular testing technology brings many conveniences, its adoption and adoption also face significant challenges due to economic considerations. Factors such as testing costs, insurance coverage, and consumers' ability to pay have a direct impact on the market acceptance and penetration of at-home molecular testing products. In the future, how to balance technological innovation, product quality and cost-effectiveness will be the main problem in the field of home molecular testing. At the same time, policymakers, insurers, and manufacturers need to work together to explore more cost-effective testing options to ensure that more people can afford and benefit from them, and to promote the widespread adoption and development of at-home molecular testing technologies.

Evolution of Home Molecular Testing TechnologyPCR and Rapid Antigen TestingThe two mainstream technologies in the field of home molecular testing, polymerase chain reaction (PCR) and rapid antigen testing, each have their own unique advantages and limitations. Due to its high sensitivity and specificity, PCR technology occupies an important position in molecular diagnosis. Through repeated amplification of target DNA fragments, PCR is able to detect very small amounts of genetic material, enabling the detection of early diseases. However, traditional PCR techniques require complex instrumentation and specialized operators, which poses a significant limitation in home use scenarios. Compared with PCR, rapid antigen tests are widely popular because of their ease of operation and rapid results. These tests typically give results within 15 minutes and are ideal for situations where immediate answers are required. Although rapid antigen tests are generally less sensitive and specific than PCR, they provide a practical solution in certain situations, such as mass screening campaigns. Sensitivity and specificity: PCR technology is significantly more sensitive and specific than rapid antigen tests for the detection of genetic material. This makes PCR the method of choice for early detection of pathogens. Speed of results: The main advantage of rapid antigen tests is the ability to provide results quickly, which is especially important for rapid prevention and control measures. Ease of operation: From the perspective of ease of operation, rapid antigen tests are more advantageous in home self-testing due to their simple operation steps. Cost considerations: Rapid antigen tests are typically less expensive than PCR tests, especially in self-testing scenarios at the individual or household level.
As an innovative molecular diagnostic method, isothermal nucleic acid amplification technology (LAMP) has been widely used in the field of home molecular testing in recent years. The biggest advantage of LAMP technology over traditional PCR technology is its ability to perform rapid amplification of nucleic acids at a constant temperature, which greatly simplifies the operation process and shortens the detection time. The LAMP technique relies on a specially designed set of primers and an enzyme with high replication efficiency that recognizes six distinct regions of the DNA sequence of interest, ensuring high specificity of the assay. At a constant temperature (typically 60-65°C), LAMP can complete hundreds of millions of DNA replications in just a few tens of minutes, achieving highly sensitive detection of small nucleic acid samples. Easy to operate: LAMP technology does not require complex temperature cycling equipment, which greatly reduces the cost and difficulty of operation, making this technology very suitable for home and field rapid testing. Fast assays: From sample preparation to result output, LAMP technology typically takes less than an hour, much faster than traditional PCR. High sensitivity and specificity: LAMP technology achieves highly specific recognition and efficient amplification of target sequences through specially designed primer combinations, enabling accurate detection even at very low nucleic acid concentrations. Adaptability: LAMP technology has low requirements for sample processing and can adapt to different sample types, including blood, saliva, etc. With the development and maturity of LAMP technology, its application in the field of home molecular testing is becoming more and more extensive. From rapid detection of infectious diseases to screening for hereditary diseases, LAMP technology has shown great potential. Especially during the COVID-19 pandemic, LAMP technology has become a powerful tool for epidemic prevention and control due to its fast and efficient characteristics.
Technological Advancements During COVID-19The COVID-19 pandemic has undoubtedly accelerated the development and innovation of molecular testing technologies in the home. In the face of an unprecedented global health crisis, researchers, research institutes, and businesses are investing in the research and development of rapid diagnostic technologies to improve the accessibility, accuracy, and speed of testing. During this period, we have witnessed a number of breakthroughs in key technologies that have revolutionized the field of home molecular testing.
Rapid development and applicationIn the early days of the epidemic, in the face of the surge in demand for testing, rapid diagnosis became the key to epidemic prevention and control. Although the traditional PCR technology is highly accurate, its complex operation process and long wait time for results obviously cannot meet the urgent needs. This challenge has led to more streamlined and rapid testing techniques, including self-testing kits using LAMP technology. These kits can be used at home, greatly improving the convenience and efficiency of testing.
Technological innovationDuring the pandemic, technological innovation has become the core driving force for the development of at-home molecular testing. For example, some new detection platforms can realize the simultaneous detection of multiple pathogens by integrating microfluidic chip technology, which is of great significance for multiple diseases that are circulating at the same time. In addition, smartphone applications have also been introduced into home testing, where users can read the test results by simply using the phone's camera, which not only improves the user experience, but also further reduces the cost and technical barrier to entry for detection.
Data Sharing and TelehealthDuring the COVID-19 pandemic, the importance of telehealth and data sharing has become increasingly prominent. The data of the home molecular test can be uploaded to the cloud in real time for remote analysis and diagnosis by doctors. This not only speeds up the diagnosis of diseases, but also provides patients with more convenient and safe medical care. With the continuous advancement of technology, home molecular testing is expected to become an important part of the telemedicine system in the future.
The application of at-home molecular testing expands to COVID and influenza: the rise of dual testingWith the global health crisis brought about by the COVID-19 pandemic, people have put forward higher requirements for the diagnosis and management of respiratory diseases. In particular, the similarities between the symptoms of the new coronavirus and the influenza virus have made it possible to detect both viruses at the same time. The development of this dual detection technology not only improves the efficiency and accuracy of diagnosis, but also brings a new application direction to the field of home molecular testing. Although COVID-19 and influenza have different types of viruses, in the early stages, the symptoms of both are very similar, including fever, cough, and difficulty breathing. This similarity in symptoms makes it difficult for both doctors and patients to distinguish between the two diseases based on clinical manifestations alone. Therefore, it is particularly important to be able to detect both the new coronavirus and influenza viruses at the same time, which can accurately diagnose in a short period of time and guide more effective treatment options. The development of dual detection technology has utilized advanced molecular biology methods, including but not limited to PCR and isothermal nucleic acid amplification (LAMP) techniques. These technologies enable the simultaneous identification of specific genetic markers for both the novel coronavirus and influenza viruses, enabling rapid and accurate detection. However, how to further streamline the testing process, reduce costs, and ensure safe and effective use in the home environment remain major challenges. With the continuous improvement and popularization of dual detection technology, the application scope of home molecular testing will be further expanded. This will not only provide families with a more convenient and accurate means of diagnosing diseases, but will also help ease the pressure on healthcare facilities, especially during flu season and high outbreaks. In the future, with the innovation of more disease marker identification and detection technologies, home molecular testing is expected to become an important tool for disease prevention and health management.
In-home testing of sexually transmitted infections (STIs)With the rapid development of home molecular testing technology, at-home testing of sexually transmitted infections (STIs) has become possible, bringing revolutionary changes to personal health management. This change not only makes early detection and treatment of STIs more feasible, but also reduces detection delays due to social labeling and privacy concerns. Sexually transmitted infections (STIs) remain a major public health problem globally, and early detection and treatment are essential to control the spread of STIs. However, traditional STIs testing often requires a visit to a healthcare facility, which not only increases the risk of infection, but also may make some people hesitate due to concerns about personal privacy and social bias. The advent of at-home detection technology provides a testing option that is both secure and privacy-preserving. The latest at-home molecular testing technologies, such as assay kits based on isothermal nucleic acid amplification (LAMP) and CRISPR gene editing technologies, have made at-home testing of STIs a reality. The advantage of these technologies is that they provide fast (typically within 30 minutes) and accurate test results, allowing users to complete the sample collection and testing process on their own with a simple operation.
Respiratory diseases and other application areasWith the continuous advancement of home molecular testing technology, its application fields are rapidly expanding, especially in the detection of respiratory diseases. Experience during the COVID-19 pandemic has shown the importance of rapid and accurate at-home testing to control outbreaks and protect public health. In the future, this technology is expected to be applied to a wider range of respiratory disease detection, including but not limited to influenza, pneumonia, bronchitis, etc., to provide more comprehensive health protection for individuals and families.
The Importance of Respiratory Disease DetectionRespiratory diseases are one of the most common health problems worldwide, and timely and accurate diagnosis is essential for the treatment and control of the disease. Traditional testing methods often need to be done through hospitals or clinics, which is not only time-consuming and labor-intensive, but also increases the risk of cross-infection. The development of home molecular testing technology has enabled individuals to quickly understand their health status and take appropriate measures without leaving their homes.
Possibilities Brought by Technological AdvancesWith the rapid development of fields such as molecular biology and bioinformatics, home molecular detection technology is becoming more efficient and accurate. For example, detection kits using CRISPR gene editing technology can accurately identify genetic markers for specific pathogens in a short period of time. This technological advancement not only provides new tools for the detection of respiratory diseases, but also opens the door to home testing for other types of diseases, including but not limited to early screening for infectious diseases, genetic diseases, and even cancer.
With the continuous improvement of technology and the further reduction of costs, home molecular testing is expected to become a routine means of daily health management. It can be applied not only for early screening and diagnosis of common diseases, but also for disease prevention and health risk assessment. In addition, combined with mobile health applications and cloud data analysis, home molecular testing can also provide personalized health management suggestions and formulate a more scientific and reasonable healthy life plan for users.
