Molbio’s official history identifies Dr. Chandrasekhar Nair as the person who established Bigtec Labs in Bengaluru in 2000, with the objective of converting scientific ideas into market-ready diagnostic products.

Who Founded Bigtec Labs?

Bigtec Labs was founded by Dr. Chandrasekhar Nair in Bengaluru in 2000.

His work focused on developing practical molecular-diagnostic technology rather than limiting PCR testing to large centralized laboratories. This approach eventually became important to the development of portable molecular testing systems.

Bigtec’s research expertise and Molbio’s commercialization capabilities subsequently came together around the development of the Truenat platform.

The relationship is particularly significant because Truenat was designed around the idea that molecular testing should not always require a large centralized laboratory. The system was developed to bring PCR-based diagnostic capability closer to patients and primary healthcare facilities.

What Does Bigtec Labs Make?

Bigtec Labs is best understood as a molecular-diagnostics technology and R&D company.

Its technology work has included areas such as:

  • Real-time PCR
  • Nucleic-acid amplification
  • Sample preparation
  • DNA/RNA extraction
  • Microfluidic and lab-on-chip concepts
  • Portable molecular diagnostics
  • Point-of-care testing
  • Automated diagnostic workflows
  • Disease-specific molecular assays
  • Miniaturized PCR systems
  • Diagnostic instrumentation and platform development

Rather than publishing a simple number of individual “products,” it is more accurate to discuss Bigtec’s major technology platforms and R&D contributions.

Its most important commercial connection is the Truenat ecosystem, which combines portable instrumentation with disease-specific molecular tests.

Bigtec Labs and the Truenat Technology

One of the most important achievements associated with Bigtec Labs is its contribution to the technology behind Truenat.

Truenat is a portable, battery-operated, real-time PCR platform designed to perform molecular testing closer to the point of patient care.

The system is designed to work in environments where conventional laboratory infrastructure may not be readily available.

According to Molbio, Truenat is fully automatic, portable and battery operated and is intended for applications ranging from urban hospitals to remote healthcare facilities.

The platform has been designed around several important principles:

1. Portability

Traditional PCR laboratories can require dedicated laboratory space, electrical infrastructure, trained personnel and multiple pieces of equipment.

Truenat was designed to reduce these infrastructure requirements.

2. Battery Operation

Battery operation makes the system useful in healthcare environments where reliable electricity can be a challenge.

3. Real-Time PCR

The platform uses real-time PCR technology to identify specific nucleic-acid targets associated with diseases.

4. Decentralized Testing

Instead of transporting every sample to a large central laboratory, testing can potentially be performed closer to where the patient is receiving care.

5. Disease-Specific Assays

The same underlying platform can support different molecular tests through dedicated assays.

This makes the system more flexible than a diagnostic instrument designed for only one disease.

How PCR Technology Works in Bigtec’s Diagnostic Approach

PCR, or Polymerase Chain Reaction, is a molecular technique used to amplify specific sections of DNA.

For RNA-based pathogens, such as many viruses, the process generally involves converting RNA into complementary DNA before amplification.

A simplified molecular diagnostic workflow can be described as:

Patient Sample → Sample Preparation → Nucleic Acid Extraction → Amplification → Real-Time Detection → Diagnostic Result

The challenge is making every stage reliable while reducing the size, complexity and infrastructure requirements of the overall system.

Bigtec’s technology development has focused on solving exactly this type of engineering and diagnostic problem.

Truenat Product Ecosystem

Truenat is not simply one PCR machine. It is an integrated diagnostic ecosystem containing instruments, sample-processing components and disease-specific tests.

The platform has been used for testing for numerous infectious diseases.

Molbio currently describes applications including:

  • Tuberculosis
  • HIV
  • Malaria
  • Viral hepatitis
  • COVID-19
  • Dengue
  • Chikungunya
  • Influenza
  • HPV
  • Cholera
  • Leprosy
  • HLA-B27 and other markers

Molbio says the Truenat technology is patented in more than 100 countries.

Tuberculosis Diagnostics

Tuberculosis has been one of the most important applications of the Truenat technology.

The system was designed to enable molecular detection of TB closer to the point of care, including settings where conventional laboratory facilities may be limited.

WHO recommendations in 2020 recognized Truenat molecular assays for initial testing for pulmonary tuberculosis and rifampicin resistance.

This represented an important development because molecular testing can provide information that is much more clinically useful than relying exclusively on conventional microscopy.

COVID-19 and Outbreak Response

The technology also became particularly important during the COVID-19 pandemic.

Because Truenat was already designed as a portable molecular testing platform, its underlying technology could be adapted for SARS-CoV-2 testing.

This demonstrated an important advantage of a flexible molecular platform: once the instrument and workflow are established, new assays can potentially be developed for emerging diseases.

Molbio describes Truenat as having been used during multiple outbreaks, including H1N1, chikungunya, COVID-19 and Nipah.

How Many Products Does Bigtec Labs Have?

Bigtec Labs should not be described as having a fixed number of conventional medical devices in the same way as a large hospital-equipment manufacturer.

Its work is better represented through technology platforms, diagnostic instruments, assay systems and R&D technologies.

The principal commercial ecosystem associated with its technology is Truenat, which includes:

  • Molecular diagnostic analyzers
  • Sample preparation systems
  • PCR testing modules
  • Disease-specific diagnostic assays
  • Digital/reporting components
  • Supporting consumables

Molbio’s current Truenat platform has expanded significantly beyond its original applications and is now positioned as a multi-disease molecular diagnostic system.

Where Are Bigtec Labs Products Sold?

Because Bigtec Labs operates within the Molbio ecosystem, its technology reaches markets through Molbio’s commercial and distribution network.

Molbio has reported international deployment of Truenat in more than 85 countries, while other company and industry sources have reported more than 80 countries and more than 10,000 systems deployed.

The technology has therefore moved well beyond the Indian market and is used particularly in settings where decentralized molecular diagnostics can provide a significant healthcare advantage.

International applications include healthcare systems in:

  • Asia
  • Africa
  • Middle East
  • Latin America
  • Other emerging and developed healthcare markets

The exact country list and installed-base figure can change as new markets are added, so these numbers should be treated as reported figures rather than a permanent product count.
