INFLUENZA • It is commonly known as FLU. • An infectious disease which is caused by an influenza virus. • This is a viral infection that attacks the respiratory system. • There are two main types of influenza virus : Types A and B. • These viruses that routinely spread in people are responsible for seasonal flu epidemics each year.
SYMPTOMS OF INFLUENZA • High Fever • Runny nose • Sore throat • Muscle Pains • Headache • Coughing • Feeling tired.
INFLUENZA TESTING METHODS The diagnostic tests available for influenza include • Viral Culture • Serology • Rapid Antigen Testing • RT-PCR • Rapid Molecular Assays • Immunofluorescence Assays
Viral Culture • The samples are placed with a cell type that the virus being tested for is able to infect. • The collection of some respiratory samples for viral culture is essential for determining te influenza A virus subtypes. • Influenza A and B virus strains causing illness. • Traditional viral culture has been generally superseded by shell vial culture. • The viral growth is measured by antigen detection methods.
Serology • It is the scientific study of serum and other bodily fluids. • The term usually refers to the diagnostic identification of antibodies in the serum. • They are typically formed in response to an infection against other foreign proteins. • This blood test help to diagnose patients with certain immune deficiencies associated with the lack of antibodies. • These methods are used to identify antibodies and antigens in patients sample which is serum and plasma.
RIDT • RIDT- Rapid Influenza Diagnostic Test • These are immunoassays that can identify the presence of influenza A and B viral nucleoprotein antigens in respiratory specimens • It displays the result in a qualitative way. • It produces quick result.
Immunofluorescence Assays • It is a technique which is used for light microscopy with a fluorescence microscope. • It is used primarily on microbiological samples. • It uses the specificity of antibodies to their antigen to target fluorescent dyes to specific biomolecule target within the cell. • It allows the visualisation of the distribution of the target molecule through the sample.
RTPCR • Real Time Polymerase Chain Reaction. • It is also known as QPCR - Quantitative Polymerase Chain Reaction. • This is a laboratory technique of molecular biology based on the polymerase chain reaction. • It monitors the amplification of a targeted DNA molecule during the PCR • It can be used quantitatively and semiquantitatively
Conclusion • Early detection helps to protect us from the influenza virus. • Freiburg Medical Laboratory in Dubai offers influenza test to counter the spread of influenza rapidly.
