Feluda: India's First Paper Based Covid-19 Test Kit

Scientists at CSIR have devised a paper based test kit to diagnose coronavirus in an efficient manner. Read on to know more.

The last few months have been testing times for the world. With slow and steady advancements towards building and implementing measures to fight the Coronavirus, multiple countries are trying to contain the spread of the same.

While India still fights, scientists from CSIR, New Delhi have devised a rather efficient and time sensitive method of diagnosing the virus. Named after a fictional character born out of the mind of Satyajit Ray, Feluda is the newest innovation put forth to fight the virus.


Feluda, an abbreviation for 'FNCAS9 Editor Linked Uniform Detection Array' is a paper based diagnostic test, made for an easier detection of the coronavirus in a suspected patient’s body. Scientists Dr. Debojyoti Chakraborty and Dr. Souvik Maiti have formulated the test in-house, with the seal of approval from Drugs Controller General of India (DCGI).

Bearing a visual resemblance to pregnancy tests available in the market, the indications on the test are quite similar and simple to understand. The test requires the suspected patient to place a blood or saliva sample on the diagnostic kit and in the case of testing positive for the virus, the paper strip displays two lines. The test also uses the CRISPR-cas9 gene editing system to detect the presence of the virus in a sample.


While the working mechanism of the test is fairly simple, the kit will be put to use only in designated pathology labs. The Tata group has come forward to take the responsibility of mass-producing the diagnostic kits and Feluda is expected to hit the market at a fourth of the rates of the current test kit pricing.

The affordable pricing and the reduced wait time to acquire results will prove extremely efficient in spotting and controlling the spread of the virus, eventually helping the country in multiple ways. Stay tuned to this space for all further information.
