What is laboratory approach towards diagnosis of viral infection?
The traditional approaches to laboratory diagnosis of viral infections have been (1) direct detection in patient material of virions, viral antigens, or viral nucleic acids, (2) isolation of virus in cultured cells, followed by identification of the isolate, and (3) detection and measurement of antibodies in the …
What are the different laboratory techniques methods used in studying viruses?
A few of the most commonly used methods include: Virus neutralization (VN) • Hemagglutination inhibition (HI) • Enzyme linked immunosorbent assay (ELISA) • Indirect fluorescent antibody (IFA) • Complement fixation (CF) • Agar-gel immunodiffusion (AGID) • Agar-gel precipitin (AGP) • Latex agglutination (LA).
What BSL is Nipah virus?
Nipah virus is a biosafety level 4 (BSL-4) pathogen that causes severe respiratory illness and encephalitis in humans.
What is the meaning of laboratory diagnosis?
a. The act or process of identifying or determining the nature and cause of a disease or injury through evaluation of patient history, examination, and review of laboratory data.
What viral diagnostic tests are appropriate for detecting respiratory tract viruses?
PCR testing can detect the most common respiratory viruses and, if identifying the specific pathogen is important for treatment, is typically the recommended methodology.
What blood test indicates viral infection?
Serology testing for the presence of virus-elicited antibodies in blood is one of the methods used commonly for clinical diagnosis of viral infections. However, standard serology-based tests have a significant limitation: they cannot easily distinguish active from past, historical infections.
Is Nipah a biological weapon?
Recently few years back one new brain damaging virus was discovered which although was a natural phenomenon emergence but many scientists considered it as a biological weapon named as Nipah Virus( NiV). It is a form of zoonosis and is a life threatening disease for both animals and human beings.
What type of virus is Nipah?
Nipah (Nee-pa) viral disease is a zoonotic infection caused by Nipah virus (NiV), a paramyxovirus belonging to the genus Henipavirus of the family Paramyxoviridae. It is a biosafety level-4 pathogen, which is transmitted by specific types of fruit bats, mainly Pteropus spp.
What is the purpose of laboratory investigations?
Laboratory tests are often part of a routine checkup to look for changes in your health. They also help doctors diagnose medical conditions, plan or evaluate treatments, and monitor diseases.
How is Covid 19 diagnosed in the laboratory?
The gold standard for the diagnosis of SARS-CoV-2 infection is the identification of viral genetic material by RT-PCR, in different samples, with greater sensitivity in bronchoalveolar lavage and nasopharyngeal swab.
How is Nipah virus (NiV) infection diagnosed?
Nipah virus (NiV) infection can be diagnosed during illness or after recovery. Different tests are available to diagnose NiV infection. During early stages of the illness, laboratory testing can be conducted using real time polymerase chain reaction (RT-PCR) from throat and nasal swabs, cerebrospinal fluid, urine, and blood.
Which immunomodulating proteins determine disease course in Nipah virus (Nipah)?

It is a biosafety level-4 pathogen, which is transmitted by specific types of fruit bats, mainly Pteropusspp. which are natural reservoir host.
