Human Parainfluenza Virus 4

The Human Parainfluenza Virus 4 test measures the presence of genetic material (RNA) of the Human Parainfluenza Virus (HMPV) 4. Although HPIV-4 infections are generally less common and less severe compared to other parainfluenza viruses, they can still contribute to upper and lower respiratory tract infections, particularly in young children, the elderly, or individuals with compromised immune systems. The test requires a nasopharyngeal swab sample and uses Real-time PCR technology to detect the presence of the virus. A positive result indicates an active HPIV-4 infection, while a negative result shows no virus was detected at the time of testing. This test helps distinguish HPIV-4 infections from other viral respiratory illnesses, ensuring proper diagnosis and timely treatment to reduce the risk of complications.
