Topic: qPCR Infectious Disease Diagnostics
Many new words have entered the collective consciousness in 2020. Among them are COVID, Coronavirus, R0 (or R naught) number, and PCR or qPCR.
Since qPCR is near and dear to us at CUUR Diagnostics, let’s take a closer look at what it is and why it is important that your COVID-19 (and other infectious disease) testing is done using this method.
Polymerase Chain Reaction

Polymerase Chain Reaction, sometimes called Molecular Photocopying,” and is a fast and inexpensive way to amplify small segments of a persons DNA. Amplification is important to help in detecting very small amounts of viral material.

Kary B. Mullis was awarded the Nobel Prize for Chemistry in 1993 for the important discovery of this technique.

Going a step (or two steps) further, quantitative PCR or qPCR adds two important elements to the standard PCR process.

• Florescent dye

• Fluorometer (a device used to measure parameters of visible spectrum fluorescence)

In combination with appropriate standard curves and reference values, this real-time information about reaction rates and times translates into information about relative and absolute amounts of DNA present.

These two elements turn qPCR from a processing step in another procedure – to a measurement technique in its own right. 

Thermal cyclers meant for use with qPCR include a fluorometer to detect that fluorescence.

The fluorometer detects that fluorescence in real time as the thermal cycler runs, giving readings throughout the amplification process of the PCR.

As a result, quantitative PCR is also called real-time PCR or RT-PCR.

This technology and process makes it possible to “multiplex” qPCR and measure multiple DNA targets, as long as each target’s corresponding probe fluoresces at a different frequency.

The Infectious Disease Diagnostic Gold Standard

Due to its extreme accuracy and a quick results, qPCR is considered the gold standard of infectious disease diagnostic testing.

CUUR Diagnostics uses qPCR exclusively in the testing of all our infectious disease panels

  • Respiratory with COVID-19 Panel
  • UTI Panel
  • Skin and Wound Panel
  • Vaginal Microbiota Panel
  • Nail Panel
  • STI Panel
  • Antimicrobial Resistance Panel
  • and our Custom Panels

COVID-19 is primarily a blood born virus mainly effecting the upper respiratory tract. Acute respiratory infection is a leading cause of death in children and contributes to a substantial amount of mortality in geriatric and immunocompromised patients worldwide. Co-infection with multiple organisms is also common within these patient populations and making clinical decisions more complex. To be effective, providers require access to advanced technologies that can detect multiple pathogens at once reducing the chance of false negative test results that can lead to a delayed or incorrect diagnosis and poor clinical outcomes.

It is important that a patient know what type  of test or diagnostic tools their provider use. The qPCR gold standard ensures the infectious disease sample is tested with extreme sensitivity to the target virus – in this example SAR-CoV-2 or COVID-19. 

It is possible for some test types to render less accuracy.
