What is PCR System? Types & Why PCR is Becoming Popular
In today’s world of modern healthcare and molecular biology, the PCR system has become one of the most powerful diagnostic and research tools. Whether in hospitals, laboratories, or research centers, PCR (Polymerase Chain Reaction) is now considered an essential system for detecting infectious diseases, genetic disorders, and conducting scientific studies.
🔬 What is PCR System?
PCR (Polymerase Chain Reaction) system is a laboratory technique used to amplify small fragments of DNA or RNA. In simple words, it can create millions of copies of a specific DNA/RNA sequence, making it easier for scientists and doctors to study or detect the presence of certain diseases.
PCR machines (also known as thermal cyclers) use repeated heating and cooling cycles to replicate DNA/RNA. This method is highly accurate, sensitive, and fast compared to traditional diagnostic tests.
⚙️ Types of PCR Systems
Over time, PCR technology has advanced into different forms to meet various medical and research needs. The most common types of PCR systems include:
1. Conventional PCR
-
The original form of PCR.
-
Used mainly for DNA amplification in research.
-
Requires gel electrophoresis to view results.
2. Real-Time PCR (qPCR)
-
Also known as quantitative PCR.
-
Detects and measures DNA/RNA in real time.
-
Widely used in hospitals for disease diagnosis (e.g., COVID-19, tuberculosis, hepatitis).
3. Reverse Transcription PCR (RT-PCR)
-
Used to detect RNA viruses (like SARS-CoV-2, HIV, influenza).
-
Converts RNA into DNA before amplification.
-
Gold standard for infectious disease detection.
4. Multiplex PCR
-
Can detect multiple pathogens in a single test.
-
Saves time and reduces costs in clinical diagnostics.
5. Digital PCR (dPCR)
-
The most advanced type.
-
Provides high sensitivity and precise quantification of DNA/RNA.
-
Useful in cancer research, prenatal testing, and detecting rare mutations.
📈 Why PCR System is Becoming Popular?
The PCR system is gaining popularity worldwide, especially in Bangladesh and other developing countries, due to several reasons:
-
Accurate & Reliable Results – PCR can detect even the smallest amounts of pathogens.
-
Early Disease Detection – Helps identify infections at an early stage, improving patient outcomes.
-
Fast Turnaround Time – Results can be available within hours, compared to traditional culture-based tests that take days.
-
Wide Application – Used in healthcare, agriculture, food safety, forensics, and genetic research.
-
COVID-19 Pandemic Awareness – The global demand for RT-PCR testing during COVID-19 made this system a household name.
-
Growing Investment in Diagnostics – Hospitals and diagnostic centers are increasingly installing PCR systems to meet rising demand.
🌍 PCR System in Bangladesh
In Bangladesh, the demand for PCR machines has grown rapidly, especially after COVID-19. Many diagnostic centers and hospitals are now adopting real-time PCR and RT-PCR systems to provide reliable diagnostic services. With healthcare modernization, PCR systems are expected to become standard equipment in most advanced diagnostic labs.
✅ Conclusion
The PCR system is more than just a laboratory machine—it is the backbone of modern diagnostics and research. From detecting infectious diseases to advancing genetic research, PCR has revolutionized healthcare. With its accuracy, speed, and versatility, it’s no surprise that the PCR system is becoming increasingly popular worldwide.
If you are planning to set up a diagnostic center in Bangladesh, investing in a PCR system can ensure long-term growth and credibility in the healthcare sector.
