How to Properly Collect an Anterior Nasal Specimen

Collecting an anterior nasal specimen, often referred to as a “nasal swab,” is a common medical procedure used to detect various conditions and infections, such as the influenza virus or COVID-19. Proper sample collection is crucial to ensure accurate test results and patient safety. In this blog post, we’ll guide you through the step-by-step process of collecting an anterior nasal specimen.

Preparing for Nasal Swab Collection

Before beginning the sample collection, it’s important to ensure you have all the necessary equipment, including:

• A sterile nasal swab
• Personal protective equipment (PPE), such as gloves, a face mask, and a gown
• A clean, well-lit work area

Collecting the Anterior Nasal Specimen

• Wash your hands: Thoroughly wash your hands with soap and water or use an alcohol-based hand sanitizer.
• Don PPE: Put on your gloves, face mask, and gown.
• Tilt the patient’s head: Gently tilt the patient’s head back and ask them to gently close their eyes.
• Tilt the patient’s head: Gently tilt the patient’s head back and ask them to gently close their eyes.
• Insert the swab: Carefully insert the swab into the nostril, angling it slightly upward and toward the back of the nasal cavity. Gently rotate the swab and leave it in place for 10-15 seconds.
• Repeat on the other side: Repeat the same process in the other nostril using the same swab.
• Remove the swab: Slowly withdraw the swab, taking care not to touch any surfaces or the patient’s skin.

Properly Handling the Specimen

• Place the swab in the transport media: Immediately place the swab in the appropriate transport media or container, as specified by the testing laboratory.
• Label the specimen: Clearly label the specimen with the patient’s information, the date and time of collection, and any other relevant details.
• Store the specimen: Store the specimen at the recommended temperature, usually between 2-8°C (36-46°F), until it can be transported to the laboratory.
