Final answer:
A nasopharyngeal swab is not used to directly diagnose RSV. Instead, a viral antigen test or a PCR test is used to detect the presence of respiratory syncytial virus (RSV) in a patient's respiratory sample.
Step-by-step explanation:
The statement 'A nasopharyngeal swab is used to make the diagnosis of RSV' is false. A nasopharyngeal swab is not used to directly diagnose RSV. Instead, a viral antigen test or a PCR test is used to detect the presence of respiratory syncytial virus (RSV) in a patient's respiratory sample, such as nasal or throat swabs. The viral antigen test looks for specific viral proteins, while the PCR test amplifies and detects the viral genetic material.
