Debunking Misconceptions in Molecular Diagnostics | ANCHOR Diagnostics
PCR (Polymerase Chain Reaction) testing has long become a cornerstone of modern infectious disease diagnostics. However, in today’s fast-paced healthcare environment, a number of persistent myths continue to shape lab decisions sometimes with unintended consequences. At ANCHOR Diagnostics, we believe clarity is key to clinical confidence. So, in this edition of our Myth vs Fact series, we’re tackling five common misconceptions about PCR diagnostics - and setting the record straight.
Myth 1: PCR testing always takes several hours to complete.
Fact: Modern PCR workflows, like those at ANCHOR Diagnostics, are optimized to deliver accurate, high-quality results in just 30 minutes - without compromising sensitivity or precision.
For years, PCR has been associated with long processing times and lab bottlenecks. But science has moved forward. At ANCHOR, we’ve designed our assays with standardized pipetting schemes and thermal profiles, so labs can move faster without losing reliability.
Thanks to workflow simplification and improved PCR chemistry, diagnostics can now deliver timely results even in time-critical scenarios, bridging the gap between urgency and accuracy.
Myth 2: All commercial PCR kits are essentially the same.
Fact: Assay design, primer specificity, and validation protocols vary significantly.
While the PCR principle is universal, the quality of a diagnostic test lies in its components: primer design, gene targets, reagent composition, and internal controls. Poorly designed assays can result in cross-reactivity or reduced sensitivity for emerging variants.
ANCHOR Diagnostics ensures highest sensitivity in all assays and subjects each design to rigorous ongoing surveillance to maintain top-tier specificity and sensitivity, even as new pathogen variants emerge.
Myth 3: Skilled technicians can overcome any PCR workflow challenge.
Fact: Applying PCR tests without error requires skill and experience. While solid PCR experience is valuable, even skilled technicians can encounter inconsistencies due to variations in pipetting, sample handling, or protocol differences between kits.
That’s why all ANCHOR PCR kits follow a harmonized workflow, with identical pipetting schemes and unified PCR temperature profiles. This standardization reduces training time, minimizes variability, and supports consistent performance.
Myth 4: Routine diagnostic workflows can’t be flexible
Fact: In reality, workflow flexibility is essential for efficient lab operations. It enables better adaptation to fluctuating sample volumes, staffing constraints, and urgent testing demands.
By offering high-speed PCR protocols and standardized workflows, ANCHOR PCR kits support more agile resource planning and improved resource management - without compromising reliability.
Myth 5: Accuracy Isn’t Absolute – Even with PCR
Fact: No diagnostic method is infallible - but PCR offers the highest sensitivity when performed correctly.
While PCR is among the most sensitive methods available, pre-analytical errors or sample collection issues can still affect outcomes. Recognizing these limitations is essential for appropriate result interpretation. Therefore, any diagnostic result must be interpreted in conjunction with other clinical and/or laboratory findings.
With ANCHOR Diagnostics PCR kits, we ensure clear instructions for use (IFU) and supportive documentation that help labs achieve consistent testing performance
Understanding the science behind molecular testing helps labs make better decisions for clinicians, patients and their daily practice. At ANCHOR Diagnostics, we don’t just sell PCR kits - we partner with laboratories to promote precision, trust, and diagnostic excellence.
