Influenza A+B Test for Sale

The Influenza A+B Test is a rapid diagnostic assay designed to detect and differentiate between Influenza A and Influenza B viruses in respiratory specimens. It is commonly used in clinics, hospitals, emergency rooms, and point-of-care (POC) settings to aid in the timely diagnosis and management of flu infections.


Key Components

Test Device/Cassette: Contains antibodies specific to Influenza A and B antigens.

Nasopharyngeal (NP) or Throat Swab: Used to collect respiratory samples.

Extraction Buffer: Helps release viral antigens from the sample.

Dropper/Applicator: For transferring the sample to the test device.


How It Works

The test utilizes immunochromatographic technology to detect viral nucleoproteins. When a sample is applied, it migrates along the test strip, binding to antibodies that produce visible lines (positive result) for Influenza A, Influenza B, or both. A control line confirms proper test function.


Intended Use

Rapid screening of symptomatic patients (fever, cough, sore throat, fatigue).

Differentiation between Influenza A and B for appropriate treatment decisions.

Infection control in outbreaks (schools, nursing homes, workplaces).


Regulatory Approvals

FDA-Cleared (for specific tests) or CE-Marked (for EU compliance).

Steps for Using a Influenza A+B Test

1. Preparation

Read Instructions: Carefully review the test kit’s package insert before performing the test.

Gather Materials: Ensure you have the test device, nasal/throat swab, extraction buffer, and timer ready.

Room Temperature: Allow the test components to reach room temperature (15-30°C) if stored cold.


2. Sample Collection

Nasal Swab: Insert the sterile swab into the nostril (about 2-3 cm deep) and rotate it gently for 10 seconds to collect secretions.

Throat Swab (if required): Swab the back of the throat (avoid touching the tongue or teeth).

Alternative Samples: Some tests may use nasopharyngeal (NP) aspirates or washes.


3. Sample Preparation

Mix with Buffer: Place the swab into the extraction tube and swirl it for 10-15 seconds.

Press the Swab: Squeeze the tube while removing the swab to release maximum liquid.

Close the Tube: Secure the cap tightly to prevent leaks.


4. Test Execution

Apply Sample: Add 3-4 drops (or as specified) of the extracted sample into the test device’s sample well.

Start Timer: Begin timing immediately after sample application.


5. Reading Results

Wait 10-15 Minutes: Check results within the recommended time (do not read after 20 minutes).


Interpretation:

Positive (A or B): A colored line appears in the control (C) and either the A or B region.

Negative: Only the control line (C) appears.

Invalid: No control line—repeat the test with a new device.


6. Disposal

Discard used swabs, tubes, and test devices in biohazard waste containers.
