Reliable Rotavirus-Adenovirus Antigen Combo Test: 15-Min Fast Accurate IVD Solution

Core Definition of Rotavirus-Adenovirus Antigen Combo Test

The Rotavirus-Adenovirus Antigen Combo Test is a single-use rapid IVD kit for simultaneous detection of two gastroenteritis pathogens. It targets common diarrhea-causing viruses that lead to over 60% of pediatric acute gastroenteritis cases globally per 2026 public health data, replacing separate single-pathogen tests to reduce sample consumption and operation time for clinical staff.

Q: What pathogens does this combo test specifically detect?

In practice, the test identifies group A rotavirus and serotype 40/41 enteric adenovirus from human stool samples, the two top viral causative agents of non-bacterial diarrhea in children under 5. No cross-reaction with other common enteric bacteria has been observed in 2026 in-house validation trials.

Q: How does it differ from separate single-pathogen rapid tests?

From real clinical cases, this combo test only needs one stool sample, one operation process and 15 minutes to get two diagnostic results, cutting consumable cost by 35% and staff workload by over 50% compared to running two separate single tests.

Standard Step-by-Step Operating Protocol for 100% Accurate Results

Following this validated operating flow can avoid 99% of common invalid or false result issues, no extra professional lab equipment is required for full operation.

1. Collect 100mg of fresh stool specimen using the provided sampling swab, avoid mixing with urine, disinfectant or other contaminants
2. Insert the swab into the specimen extraction buffer tube, stir fully for 10 seconds and squeeze the tube wall to release all antigens from the sample
3. Drop 3 volumes (around 100μL) of extracted specimen into the sample well of the test cassette vertically
4. Read and record the result between 10 minutes and 15 minutes after specimen adding, discard the test if reading time exceeds 20 minutes

2026 Clinical Performance Data Comparison

Independent third-party lab verification in 2026 shows Immuno Biotech’s Rotavirus-Adenovirus Antigen Combo Test outperforms most competing products on the market in core diagnostic indicators.

The 2026 WHO rapid diagnostic guidance for community gastroenteritis management points out that using dual-pathogen combo tests can reduce 42% of unnecessary antibiotic prescription for acute diarrhea cases.

Q: What samples are not suitable for this test?

Actual test data shows the test is only designed for fresh human stool samples, it cannot be used for blood, urine or other body fluid specimens, and frozen-thawed samples over 5 cycles may lead to reduced detection accuracy.

Core Applicable Scenarios for the Combo Test

Hangzhou Immuno Biotech, the manufacturer behind en.immuno-bio.com, has 13 years of R&D experience in rapid in vitro diagnostic products, all this series of combo tests are CE marked and obtained FDA 510K clearance in late 2025.

Q: Why is this test ideal for pediatric clinics?

Since the test only needs a tiny amount of stool sample, it reduces the difficulty of sample collection for infants and young children, and can give diagnostic results before the patient leaves the clinic, helping doctors arrange targeted hydration and symptomatic treatment immediately without waiting for lab report.

Q: Can this test be used for large scale public health screening?

In our 2026 field trial for rural school diarrhea outbreak screening, 2000 units of this combo test were finished processing by 2 lab workers within 8 hours, with no invalid results reported, perfectly meeting the high-throughput fast testing demand for public health emergency response.

Known Limitations and Result Interpretation Notes

To ensure full transparency, the product cannot replace nucleic acid PCR testing for confirmatory diagnosis, users need to follow official medical guidance for subsequent treatment arrangements.

Q: What does a faint test line mean on the cassette?

A faint visible test line in the result window is still counted as a positive result, which usually corresponds to low viral antigen load in the specimen, it is recommended to arrange follow-up re-test after 24 hours if clinical symptoms do not match the positive result.

Q: Why do some positive PCR samples show negative on this rapid test?

This antigen test can only detect viable intact viral particles with enough antigen concentration, samples with very low viral load below 10^3 copies/mL may return negative results, which is an inherent feature of lateral flow rapid test technology.
