Study Notes
Viral Nucleic Acid Detection
- PCR (Polymerase Chain Reaction) or Nucleic Acid Amplification Test (NAAT) is feasible for detecting viral nucleic acids in acute infection
Specimen of Choice for Serological Diagnosis
- Serum is the specimen of choice for serological diagnosis
Cell Culture Systems
- Virus Isolation detects the viral agent in the clinical specimen using cell culture systems
Production of Detectable Antibody
- Production of detectable antibody for serological diagnosis is feasible in acute infection around 7-10 days after symptom onset or 10-14 days after infection
