Molecular methods allow a rapid and accurate identifying of microorganisms. Molecular microbiology includes methods of diagnosing bacteria, viruses and parasites on which cultures cannot be obtained or if they can these would take much too long. Polymerase chain reaction (PCR) is used in microbiology to amplify (replicate many times) a single DNA sequence. DNA based methods allow for identification of the disease factor directly from the sample. This technique is used in molecular microbiology to detect the presence of pathogens in a sample. It is also used to determine the genetic differences between two microbial strains.
These methods thus allow for a disease to be diagnosed rapidly and assist in treatment to be provided as soon as possible. Many tests using quantitative and qualitative analysis methods can be carried out at Inci Laboratories.
