Molecular Diagnostics


The Molecular Diagnostic Laboratory uses state-of-the-art methods to detect DNA or RNA for diagnosis of a variety of infectious diseases.

Conventional polymerase chain reaction (PCR) tests Real-time polymerase chain reaction (PCR) tests
  • BK virus in plasma and urine (quantitative)
  • Bordetella pertussis in nasopharyngeal swabs (qualitative)
  • Cytomegalovirus in whole blood (quantitative)
  • Enterovirus in cerebrospinal fluid (qualitative)
  • Epstein-Barr virus in whole blood (quantitative)
  • Herpes simplex virus in cerebrospinal fluid (qualitative)
  • Methicillin-resistant Staphylococcus aureus (MRSA) in nasal/nasopharyngeal swabs (qualitative)
The Molecular Diagnostic Laboratory is undergoing significant expansion and will be adding many more assays for pathogenic microorganisms in the near future. In addition, the laboratory will be introducing a group of multiplex PCR assays and PCR-based microarray assays which will enable the simultaneous detection of dozens of pathogenic microorganisms in a single specimen. They also will allow the laboratory to offer many assays for diagnosis of non-infectious diseases which include molecular red blood cell antigen phenotyping and those for drug metabolism.
