A trained healthcare professional typically performs the nasal swab. Here’s a step-by-step overview: 1. The child is asked to sit still, often with the help of a parent or guardian. 2. A sterile swab is gently inserted into one nostril, reaching the designated area for sample collection. 3. The swab is rotated to collect the sample and then carefully removed. 4. The process is sometimes repeated in the other nostril to ensure adequate sample collection.
