Imagine a COVID-19 test that gives fast results, costs less, and works even in a village without a lab. During the pandemic, testing became a major challenge. RT-PCR tests were accurate but slow, expensive, and lab-dependent. Many people in remote areas could not get tested quickly. This delay made it harder to stop the spread of the virus.
A team of scientists at IIT Kharagpur decided to solve this problem. They developed a smart testing technology called COVIRAP. It is affordable, portable, and easy to use. It gives results in just 45 minutes. Users do not need a lab or trained professionals to use it.
COVIRAP changed the way people tested for COVID-19 in India. It showed how students, scientists, and engineers can build real solutions. In this article, you will learn how COVIRAP works, who created it, and why it is an important invention for the future of healthcare.
Which IIT Developed COVIRAP Technology for COVID-19?
IIT Kharagpur developed the COVIRAP technology. It became the first IIT to create such a device. The device got recognition from the Indian government. It helped fight the pandemic in India. It also showed the strength of Indian science and technology.
Development of COVIRAP by IIT Kharagpur
During the early months of the COVID-19 pandemic, one of the biggest challenges was testing. Testing helped detect the virus and control the spread. However, most tests were slow, expensive, and required special labs. RT-PCR, the gold standard test, took 3 to 4 hours or more. It also needed trained technicians, costly equipment, and a clean lab environment. This made large-scale testing very difficult, especially in rural and semi-urban areas.
At this critical time, a team at IIT Kharagpur took up the challenge. They wanted to build a testing system that would be fast, low-cost, and easy to use outside of labs. This effort led to the creation of COVIRAP — a compact, portable, and highly accurate COVID-19 testing device.
Who Led the Development?
The project was led by two key faculty members:
- Prof. Suman Chakraborty: He is a professor in the Department of Mechanical Engineering at IIT Kharagpur. He has worked on biomedical devices and low-cost healthcare technologies for many years.
- Dr. Arindam Mondal: He is a faculty member in the School of Bioscience at IIT Kharagpur. He specializes in molecular biology and virology.
Together, they formed a strong team by bringing together experts from different departments. The team included scientists and engineers from biotechnology, mechanical engineering, electronics, and computer science.
This multidisciplinary team worked with one shared goal — to build a solution that would be simple and scalable. They focused on designing a testing method that could be used by anyone, anywhere, without needing large equipment or expert training.
What Was the Main Objective?
The goal of the COVIRAP project was very clear. The team wanted to create:
- A low-cost COVID-19 testing method
- A portable device that could be used outside labs
- A fast testing process with results in under one hour
- A simple system that required minimal training
- An accurate tool that could match the results of RT-PCR tests
They also wanted to address the limitations of the RT-PCR test. RT-PCR is very accurate, but it is costly, time-consuming, and highly dependent on lab infrastructure. The COVIRAP team aimed to design a device that could solve these problems, especially for people in rural and resource-poor settings.
How Did the Team Work?
The development process began with basic research. The team studied the structure of the virus and how it could be detected through its genetic material. They focused on using isothermal nucleic acid amplification, which does not require the temperature cycles used in RT-PCR. This method makes the process faster and cheaper.
They also designed a small machine to maintain a fixed temperature for the reaction. This machine became the temperature control unit. It helped amplify the viral RNA without the need for a big lab thermocycler.
At the same time, the team worked on developing a detection method. This was done using a paper strip — similar to a pregnancy test. The strip would change color to show if the virus was present. Later, they added a smartphone app that could read and interpret the results.
These three elements — the amplification system, the paper strip, and the smartphone app — formed the core of COVIRAP. The device was small, easy to use, and gave results within 45 minutes.
Testing and Improvement
After building the first prototype, the team tested the device in different conditions. They worked with doctors, healthcare workers, and field volunteers to try it out in real-life settings. These field tests helped them improve the design.
The team made sure that people with little or no lab experience could operate the device. They trained non-medical users and tested the device outside hospitals and labs. The results were promising.
The device showed 94% sensitivity and 98% specificity, which means it could correctly detect both positive and negative cases with high accuracy. This was close to the performance of standard RT-PCR tests.
Support and Recognition
The project received strong support from the Ministry of Education and Indian Council of Medical Research (ICMR). The ICMR reviewed the data and approved the test for use. This helped COVIRAP move from the lab to real-world use.
IIT Kharagpur also supported the project through its STEP (Science and Technology Entrepreneurs Park) and Technology Transfer Office. They helped the team connect with companies that could manufacture and distribute the device.
The technology was licensed to Rapid Diagnostic Group in India and Bramerton Holdings LLC in the USA. This allowed COVIRAP to reach both Indian and international markets.
A Proud Moment for Indian Innovation
The development of COVIRAP showed what Indian scientists and engineers can achieve with focus and teamwork. It also showed that real change can start from an idea inside a classroom or lab. The team at IIT Kharagpur built a powerful tool that not only helped during a crisis but also created a path for future health technologies. This success encourages students to think beyond textbooks. It proves that with the right mindset, even a college project can turn into a life-saving innovation.
How Does COVIRAP Work?
COVIRAP is a smart and simple device that helps detect the COVID-19 virus quickly. It does not need a lab or expensive equipment. Users can use it with minimal training. The process is easy, and the results are fast and accurate. Let us understand how COVIRAP works step by step.
Key Components of the COVIRAP System
COVIRAP has three main components:
1) Automated Pre-Programmable Temperature Control Unit: This part of the device keeps the temperature stable during the test. It heats the sample to a fixed temperature that helps the virus’s genetic material (RNA) multiply. Unlike RT-PCR, COVIRAP does not need high and changing temperatures. It uses a process called isothermal amplification. This means the temperature stays the same throughout the test. This makes the machine smaller, cheaper, and easier to use.
2) Genomic Analysis Detection Unit: This part checks if the sample contains the virus. After the viral RNA is copied in the temperature control unit, it is tested using a paper strip. The strip changes color if the virus is present. It works like a pregnancy test strip. You can see the result with your eyes. No lab tools are needed.
3) Smartphone App Integration: A mobile app reads the test result using the phone’s camera. The app gives a clear result — positive or negative. It also stores the result and can send it to doctors or health officials if needed. This digital method helps in fast reporting and better tracking of cases.
Testing Process Step by Step
The COVIRAP testing process includes the following steps:
1) Sample Collection: A swab is used to collect the sample from the nose or throat. This is the same as the method used in RT-PCR tests.
2) Sample Preparation: The sample is mixed with a special liquid that contains pre-mixed reagents. These reagents help break the virus and copy its genetic material.
3) Isothermal Amplification: The sample is placed in the temperature control unit. The machine keeps the heat at a fixed level. This heat helps the viral RNA to multiply. The process is called isothermal amplification. It takes about 30 minutes.
4) Detection of Virus: After amplification, the sample is dropped onto a test strip. If the virus is present, the strip will show a colored line. This line means the result is positive. If there is no line, the result is negative.
5) Result Interpretation: You can read the result directly from the strip. Or you can scan the strip using the COVIRAP smartphone app. The app tells you the result and stores it for recordkeeping.
6) Time Taken: The whole process takes about 45 minutes. This includes sample preparation, amplification, and result interpretation. In comparison, RT-PCR tests take about 3 to 4 hours or more. COVIRAP saves time and can test more people in a day.
Advantages of COVIRAP Over Existing Tests
COVIRAP has many advantages over other COVID-19 tests like RT-PCR and FELUDA. The team at IIT Kharagpur designed it to be affordable, fast, and easy to use. This makes it a good option for large-scale testing, especially in rural and low-resource areas. Below is a simple comparison of COVIRAP with RT-PCR and FELUDA tests:
| Feature | COVIRAP | RT-PCR | FELUDA Test |
| Cost per test | ₹500 | ₹1,500–₹3,000 | Higher than COVIRAP |
| Time taken | ~45 minutes | 3–4 hours or more | ~1 hour |
| Portability | Yes (can be used anywhere) | No (lab-dependent) | No (lab-dependent) |
| Skill needed | Minimal training | Skilled technicians | Skilled technicians |
| Accuracy | 94% sensitivity, 98% specificity | Very high (Gold standard) | High, but lab-dependent |
1) Low Cost: COVIRAP is much cheaper than other testing methods. A single test costs around â‚ą500. This makes it suitable for testing large groups of people. The reusable nature of the device also helps save money over time.
2) Fast Results: COVIRAP gives results in about 45 minutes. RT-PCR tests take 3 to 4 hours, and sometimes longer if the lab is busy. FELUDA also takes about an hour but still needs special handling. COVIRAP is much quicker and easier to manage in the field.
3) Portable and Easy to Use Anywhere: COVIRAP is small and lightweight. You can carry it to villages, schools, or offices. You don’t need a full lab to run the test. RT-PCR and FELUDA require proper lab space and equipment, which limits their use in remote areas.
4) No Need for Expert Skills: RT-PCR and FELUDA tests need trained technicians to perform. COVIRAP, however, can be used after simple training. Even a basic health worker can handle the process. This helps when there are not enough skilled people in rural or emergency settings.
5) High Accuracy: In clinical tests, COVIRAP showed 94% sensitivity and 98% specificity. This means it correctly identifies most people who are infected, as well as those who are not. It comes close to the accuracy of RT-PCR.
Extra Benefits
- Reusable Machine: You can reuse the main COVIRAP device. Only the sample cartridge needs to be changed.
- Early Detection: It can detect even small amounts of the virus. This helps find cases early, even before symptoms appear.
- Ready for Future Use: COVIRAP can be adapted to test for other diseases like tuberculosis, malaria, influenza, and dengue. This makes it a smart long-term solution.
Commercialization & Global Reach of COVIRAP by IIT Kharagpur
After developing and testing COVIRAP, IIT Kharagpur focused on making it available to the public. The goal was to reach both Indian and global markets. The team wanted people in all regions, especially in rural areas, to access quick and low-cost testing. To do this, IIT Kharagpur partnered with companies in India and abroad. These partnerships helped in mass production, distribution, and further development.
Licensing Partners
IIT Kharagpur gave licenses to two major companies to produce and distribute COVIRAP:
1) Rapid Diagnostic Group (India): This company is responsible for manufacturing and distributing COVIRAP kits and devices in India. It supports the Make in India initiative.

2) Bramerton Holdings LLC (USA): This company focuses on taking COVIRAP to global markets, especially in the USA, Europe, and Southeast Asia. Bramerton helps with global approvals, marketing, and partnerships with health agencies. With their help, IIT Kharagpur’s innovation can benefit people outside India too.
Make in India Initiative
COVIRAP is an example of a fully indigenous technology. This means everything is made in India—from the hardware to the software and reagents. No imported components are needed. This keeps the cost of the device under ₹5,000, and each test costs about ₹500. The Make in India model has many benefits:
- It reduces import costs.
- It creates jobs for Indian workers.
- It builds local capacity for future healthcare tools.
- It ensures fast production without waiting for foreign supplies.
Affordable and Scalable
Since the device is reusable, and only the cartridge needs to be replaced, the testing cost stays low. Mass production also allows kits to be sent in bulk to cities, towns, and villages. Health workers can use them in mobile vans, small clinics, or even schools and offices.
COVIRAP is also suitable for emergency situations. During a virus outbreak or pandemic wave, quick and portable testing becomes important. COVIRAP allows fast testing in crowded or hard-to-reach areas.
Future Applications
IIT Kharagpur has plans to expand COVIRAP to test for more diseases. These include:
- Tuberculosis (TB)
- Malaria
- Dengue
- Influenza
All of these diseases affect millions of people, especially in developing countries. A single, easy-to-use device that can test for many infections will be very helpful.
Global Approval Process
COVIRAP has already been approved by the Indian Council of Medical Research (ICMR). For international use, the team is working on getting Emergency Use Authorization (EUA) in the USA and other regions. Once approved, the device can be used in hospitals, airports, and public health programs across the globe.
