Molecular Diagnostics - a rapidmicrobiology Special Focus


Molecular diagnostic tests can include techniques such as Polymerase Chain Reaction (PCR), real-time PCR, Whole-Genome Sequencing (WGS), Next Generation Sequencing (NGS), and Nucleic Acid Hybridization among others. Here we summarise the many advantages and some disadvantages of using these techniques in routine laboratories.

Advantages of Molecular Diagnostics in Clinical and Food Laboratories:

  • High Sensitivity and Specificity: Tests offer high sensitivity and specificity, delivering accurate detection of pathogens even when present at low concentrations.
  • Rapid Results: Molecular-based tests deliver faster results enabling more timely diagnosis and treatment in clinical settings and quicker identification of foodborne pathogens in food laboratories.
  • Multiplexing Capability: Many techniques allow for multiplexing, where multiple targets can be detected in a single test, saving time and resources.
  • Automation: Tests are often designed to be run on automated instruments, helping to address skilled staff shortages, reducing human error, and increasing efficiency.

 

Limitations of Molecular Diagnostics in Clinical and Food Laboratories:

  • Cost: Tests can be expensive, with kits tied into use only on instruments from a specific manufacturer, limiting choice.
  • Complexity: Specialized equipment and trained personnel can make them heavy on maintenance and training costs.
  • Interference: Factors like inhibitors in samples or contamination can affect the accuracy of molecular diagnostic results.
  • Limited Detection Range: Some MDx tests may have a limited detection range, missing certain pathogens or genetic variations.
  • Validation and Standardization: Ensuring the accuracy and reliability of molecular diagnostic tests requires rigorous validation and standardization processes.

In this rapidmicrobiology special focus, we showcase some options for laboratory-based molecular testing, including MWE's and Puritan's swab specimen collection and transport options ideally suited to molecular diagnostics, Himedia's HiGenoMB® range is a complete portfolio of accurate and sensitive Real-time PCR Kits for clinical diagnostics and their AMR panel includes CE/IVD approved kits for the most prevalent drug resistance observed clinically in both gram-negative as well as gram-positive bacteria.

Tianlong’s Human Papillomavirus (HPV) Nucleic Acid Detection Kit is a qualitative in vitro test for detection of 18 high-risk HPV types. As an aid in diagnosing HBV infection and as a screening test for blood and plasma donors. Recently introduced, the BioPerfectus Survival motor neuron 1(SMN1) Gene Detection Real-Time PCR Kit is intended for the in-vitro qualitative detection of Survival motor neuron 1 (SMN1) exon 7 and(or) exon 8 deletions and the copy number of SMN1 at the 7th exon and (or) the 8th exon in human EDTA anticoagulated blood samples. Beckman Coulter’s validated HBsAg High Positive algorithm eliminates the need for repeat and confirmatory testing for samples ≥ 100.00 S/CO.

For food safety laboratories there is fully automated Suretect from Thermo Fisher, GENE-Up from bioMerieux and the more portable RiboFlow® - Listeria Twin Detection Kit from SY-LAB.

For any approach, using the right standards and quality control protocols are key, Andrew Zenger, the Global Product Manager at ZeptoMetrix discusses why not relying on manufacturers-supplied QC standards are essential to achieving accurate results.
