A new blood test has been developed by the researchers at the Massachusetts Institute of Technology (MIT) and the University of California, San Diego, which can identify both past and present infections from viruses.
It is a significant breakthrough for diagnosing and treating viral infections caused by various diseases, including HIV, hepatitis, and COVID-19.
The need for a faster and accurate test
The conventional blood tests help detect viral infections but fail to determine if the virus has been contracted in the past or is still present.
The new blood test would provide a more accurate and detailed picture of the person’s current and past health status, making it easier for doctors to prescribe the right treatment.
Current tests used to determine viral infections can be slow and are often inaccurate. For example, COVID-19 tests usually take several days to provide results, and researchers estimate that around 1 in 5 COVID-19 tests provide false results.
How the new blood test works
The new blood test works by analyzing the DNA for viral infections from an individual’s blood samples and comparing them to the genome sequences of viruses already mapped and available in public databases.
It then determines how many viruses the patient has been exposed to based on the antibody response. By identifying the specific sequence of antibodies circulating in the blood, the researchers can determine the virus type and whether it is a current or past infection.

Benefits of the new blood test
The new blood test could help eliminate the need for multiple blood tests to identify different viral infections in the same patient.
This would not only reduce the burden on healthcare workers and laboratories but also save valuable time and resources.
The test is also beneficial for people with high-risk factors, such as healthcare workers, frontline personnel, and immunocompromised individuals, as it can identify past infections that could impact current or future viral infections.
It could also be used to monitor the recovery process of patients who have contracted viral infections such as COVID-19.
Conclusion
The new blood test developed by MIT and the University of California, San Diego, is a significant breakthrough for diagnosing and treating viral infections.
The ability to distinguish between past and present viral infections provides crucial information that doctors can use to prescribe the right treatment. It is also beneficial for people with high-risk factors who can be monitored for past infections that could impact future viral infections.
By reducing the need for multiple tests, this blood test saves valuable time and resources, which are crucial in the ongoing fight against viral infections.
