Respiratory Infectious Diseases respiratory viruses like influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 (COVID-19). 2. Antigen Detection Tests: Antigen tests detect specific proteins or antigens present on the surface of pathogens. These tests are rapid and provide quick results. Antigen tests are commonly used for diagnosing respiratory viruses such as influenza and RSV. 3. Antibody Testing: Serological tests detect antibodies produced by the immune system in response to an infection. Blood samples are collected to check for the presence of specific antibodies, indicating past or recent respiratory infections. Antibody tests are commonly used for respiratory diseases like COVID-19 or Mycoplasma pneumoniae infections. 4. Susceptibility Testing: In cases of bacterial respiratory infections, susceptibility testing is performed to 2. 3.
I n a laboratory setting, various tests can be performed to diagnose respiratory infectious diseases. These tests are typically conducted on samples collected from the respiratory system, such as nasal swabs, throat swabs, sputum, or bronchoalveolar lavage (BAL) fluid. Here are some common laboratory tests used for respiratory infectious disease testing: Microbiological Culture: Samples, such as swabs or sputum, are cultured on specific growth media to identify and grow bacteria or fungi causing respiratory infections. The cultured organisms are then analyzed for their characteristics and sensitivity to antimicrobial agents. 1. Molecular Testing: Polymerase Chain Reaction (PCR) and other molecular techniques can detect the genetic material (DNA or RNA) of pathogens. These tests are highly sensitive and specific, allowing for the identification of viruses, bacteria, and fungi causing respiratory infections. PCR-based tests are commonly used for diagnosing 1.
