Name of the Procedure:

Infectious agent detection by nucleic acid (DNA or RNA); Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), Influenza Virus Types A and B, and Respiratory Syncytial Virus (Multiplex Amplified Probe Technique)

Summary

This test uses advanced laboratory techniques to detect genetic material from multiple respiratory viruses, including COVID-19, Influenza A and B, and RSV, in a single sample. It is efficient and accurate at identifying the cause of respiratory infections.

Purpose

Medical Condition:

• Respiratory infections caused by SARS-CoV-2 (COVID-19), Influenza A and B, and Respiratory Syncytial Virus (RSV).

Goals:

• Rapidly identify the specific virus causing symptoms.
• Facilitate timely and appropriate treatment.
• Help prevent the spread of infectious respiratory diseases.

Indications

Symptoms:

• Fever, cough, shortness of breath, sore throat, body aches, fatigue, and other flu-like symptoms.

Patient Criteria:

• Individuals showing respiratory symptoms.
• People in close contact with confirmed cases.
• High-risk groups such as the elderly, immunocompromised, or those with chronic health conditions.

Preparation

Instructions:

• No specific dietary restrictions.
• Inform healthcare provider of current medications.
• Possibly provide a complete medical history and list of symptoms.

Tests and Assessments:

• No advanced testing needed prior to the procedure.

Procedure Description

1. Sample Collection:
   • A healthcare provider collects a sample using a nasal or throat swab.
2. Laboratory Analysis:
   • Samples are sent to a lab where nucleic acid amplification tests (NAAT) are performed.
3. Multiplex Amplified Probe Technique:
   • The technique uses probes to detect specific RNA or DNA sequences unique to SARS-CoV-2, Influenza A and B, and RSV within a single test run.

Tools and Technology:

• Swabs for sample collection.
• Laboratory equipment for NAAT and multiplex analysis.

Anesthesia:

• Not required.

Duration

• Sample collection takes a few minutes.
• Lab results are typically available within 24-48 hours.

Setting

• Outpatient clinic, hospital, or designated testing site.

Personnel

• Trained healthcare providers such as nurses or technicians for sample collection.
• Laboratory technicians and microbiologists for analysis.

Risks and Complications

Common Risks:

• Mild discomfort or gagging from the swab.
• Slight chance of nosebleed.

Rare Complications:

• Minimal risk of infection from the swab collection.

Benefits

• Rapid identification of the specific respiratory virus.
• Informs optimal treatment strategy.
• Assists in outbreak control and prevention measures.

Recovery

Post-Procedure Care:

• No specific aftercare required.
• Monitor for potential symptoms if not previously symptomatic.

Recovery Time:

• Immediate; there is no downtime required.

Follow-Up:

• Based on test results, follow healthcare provider's recommendations for treatment or isolation.

Alternatives

Other Options:

• Individual tests for each virus.

  Pros and Cons:

• Pros of Multiplex Testing:

  • Faster, comprehensive results from a single sample.
  • Reduced need for multiple testing appointments.

• Cons:

  • May not be available in all healthcare settings.

Patient Experience

During the Procedure:

• Feelings:
  • Discomfort but generally well-tolerated.

After the Procedure:

• Experience:

  • Relief in knowing prompt, accurate diagnostic information.

  Pain Management:

• No pain management required.
• Communication with healthcare providers can help soothe discomfort during swab collection.
