RSV Respiratory Syncytial Virus Ag Test

Short Description:

Respiratory Syncytial Virus (RSV) is a highly contagious virus that primarily affects the respiratory tract. It is one of the most common causes of respiratory infections, particularly in infants, young children, and elderly individuals. RSV infections range from mild, cold-like symptoms to severe respiratory illnesses such as bronchiolitis and pneumonia. The virus spreads through respiratory droplets, direct contact, or contaminated surfaces. RSV is most prevalent during the winter and early spring months, making timely and accurate diagnosis crucial for effective management and control of outbreaks.

Types of RSV Tests:
- Rapid RSV Antigen Test:
  - Uses immunochromatographic lateral flow technology to quickly detect RSV antigens in respiratory samples (e.g., nasal swabs, throat swabs).
  - Provides results in 15–20 minutes.
- RSV Molecular Test (PCR):
  - Detects RSV RNA using highly sensitive molecular techniques like reverse transcription-polymerase chain reaction (RT-PCR).
  - Requires laboratory processing but offers high sensitivity and specificity.
- RSV Viral Culture:
  - Involves growing RSV in a controlled lab environment.
  - Rarely used due to longer turnaround times.
Sample Types:
- Nasopharyngeal swab
- Throat swab
- Nasal aspirate
- Bronchoalveolar lavage (for severe cases)
Target Population:
- Infants and young children presenting with severe respiratory symptoms.
- Elderly patients with respiratory distress.
- Immunocompromised individuals with flu-like symptoms.
Common Uses:
- Differentiating RSV from other respiratory infections like the flu, COVID-19, or adenovirus.
- Facilitating timely and appropriate treatment decisions.
- Public health monitoring during RSV outbreaks.

Principle:

The test uses immunochromatographic assay (lateral flow) technology to detect RSV antigens.
RSV antigens in the patient’s respiratory sample bind to specific antibodies conjugated with gold or colored particles on the test strip.
A visible line forms at the test line (T) position if RSV antigens are present.

5.Carefully remove the swab without touching the tip.Insert the entire tip of the swab 2 to 3 cm into the right nostril.Note the breaking point of the nasal swab.You can feel this with your fingers when inserting the nasal swab or check it in the mimnor. Rub the inside of the nostril in circular movements 5 times for at least 15 seconds,Now take the same nasal swab and insert it into the other nostril.Swab the inside of the nostril in a circular motion 5 times for at least 15 seconds. Please perform the test directly with the sample and do not
leave it standing.

6.Place the swab in the extraction tube.Rotate the swab for about 10 seconds,Rotate the swab against the extraction tube,pressing the head of the swab against the inside of the tube while squeezing the sides of the tube to release as much liquid as possible from the swab.


7. Take out the swab from the package without touching the padding.	8.Mix thoroughly by flicking the bottom of the tube.Place 3 drops of the sample vertically into the sample well of the test cassette.Read the result after 15 minutes. Note:Read the result within 20 minutes.Otherwise,are petition of the test is recommended.
