Rapid Flu Test: How It Works and When to Use It

Flu is one of the viral forms that anyone can grasp during seasonal change. Even the healthiest person can experience mild to moderate symptoms, needing a confirmation test. In fact, in India, 19,872 cases were reported as of 30th October’24, and out of that, 324 resulted in an unfortunate demise. This shows how unpredictable and uncertain this minor flu, scientifically known as influenza, can be.

Here, diagnostic tests play a crucial role in confirming such infections. While some of you may think that a test for such a little thing is not worth it, it is. The unprecedented escalation of a general flu can also lead to fatality. Hence, top health insurance companies offer coverage even for such small tests.

Let's explore one of the quickest ways to detect influenza and understand the importance of timely treatment.

What is a Rapid Flu Test (RFT)?

A rapid flu test is one of the quickest diagnostic procedures that detects the presence of influenza A and B viruses. It is conducted using a nasal or throat swab. Once done with the test, you may expect the results to be available in a general timeframe of 15 to 30 minutes. This scientific advancement is one of the most valuable ones, as it supports swift detection and early treatment.

The rapid flu diagnostic test is available in the following two types:

1. Rapid Influenza Diagnostic Test (RIDT)

   This type of diagnosis is done to confirm the presence of flu antigens in about 15 minutes. While convenient for quick results, RIDTs may have lower sensitivity. What this means is that they might miss some flu cases. However, a negative RIDT result doesn't always rule out rapid influenza, especially during peak flu season.

2. Rapid Molecular Assays (RMA)

   The RMA test is another popular flu virus rapid molecular assays detection test. It has higher accuracy, meaning that the results can be expected within minutes. These tests are comparatively more sensitive and accurate than RIDTs. As a result, you may even consider them a better option if you are seeking a more reliable diagnosis. They are particularly useful when a highly accurate result is crucial for patient management or public health surveillance.

What are the Signs to Consider a Flu Test?

Every time you sneeze, feel cold, feverish, or have a runny nose, it does not necessarily mean that it is the flu. With seasonal changes, it may also occur that due to a poor immune system, you fall sick.

However, the importance of diagnosis cannot be overlooked every time. Therefore, the following are the situations when you must get yourself tested:

• Persistent Flu Symptoms: If your symptoms, including high fever, body ache, sore throat, and fatigue, last more than a couple of days, get tested immediately. Generally, the incubation period of influenza carries on from one to four days.
• High-risk Groups: Based on age, a classification of high and low-risk groups has been made. Infants, elderly individuals, pregnant women, and those with chronic illnesses fall under the high-risk group. It is suggested to get tested even during slight hints of influenza or flu.
• Outbreak Situations: Situations like a pandemic or epidemic are caused by outbreaks. If there's one at your workplace, neighbourhood, or at large, getting tested becomes necessary.

How Does an RFT or Influenza Test Work?

Diagnostic tests are generally simple in nature, and talking about this one, it hardly takes much time. Following are the steps in which this test is conducted:

1. Sample Collection: Whether you book a test at the nearest hospital or get a home-stop test, a healthcare professional will only collect your sample. The professional will use a swab to collect it from the nose or throat.
2. Testing Process: The sample afterward undergoes analysis using a testing kit that detects the presence of any flu or viral RNA antigens.
3. Results: Depending on the type of test, results are determined within minutes.
4. Next Steps: A positive result confirms the presence of the flu, so you must explore treatment options under a specialist doctor's guidance.
