HK 4 in One


Timely and accurate diagnosis of infection from respiratory viruses is essential for managing clinical care and reducing transmission. Lateral flow tests, also referred to as rapid antigen tests, are point of care devices that can identify the presence of an infectious disease by detecting microbial proteins within 30 minutes. These assays leverage the principles of immunochromatography, where specific antibodies react with target antigens, producing a visible result on a test strip.

A recent comprehensive study, led by Professor Benjamin Cowling, the Chair of Epidemiology in University of Hong Kong (HKU), conducted in an outpatient clinic in Hong Kong highlights the exceptional performance of SARS-CoV-2 &Influenza A/B &RSV Antigen Kit (Colloidal Gold) manufactured by Goldsite Diagnostics Inc. (Short as Goldsite 4 in One Combo Rapid Test in the following context), making them an indispensable tool for healthcare professionals worldwide. 

This paper suggests that multiplex rapid antigen tests are effective tools for diagnosing influenza, RSV, and SARS-CoV-2, offering a quick and reliable option for managing respiratory infections in clinical setting.

This study is supported by WHO Collaborating Centre for Infectious Disease Epidemiology and Control and Health and Medical Research Fund of Hong Kong SAR Government. As of 2024/06/25 when the article went public, this HKU study is a preprint and has not been peer reviewed.

Proven Excellence in Real-World Settings

Effective Clinical Management

The ability to rapidly and accurately diagnose multiple respiratory viruses is crucial for effective clinical management. Goldsite 4 in One Combo Rapid Test enable timely isolation and treatment decisions, thereby helping to curb the spread of respiratory virus infections.

Hong Kong Outpatient Clinic Study

The Hong Kong outpatient clinic study underscores the practical benefits of Goldsite 4 in One Combo Rapid Test. The tests were conducted in real-world settings, involving a diverse patient population. The study period was during the seasonal influenza epidemic in Hong Kong, with one epidemic peak in late April dominated by influenza A(H1N1) and a second peak in September dominated by influenza A(H3N2). An epidemic of SARS-CoV-2, dominated by Omicron XBB subvariants also occurred from April to July 2023 and therefore, the researchers expected the resulting PPV and NPV during periods of higher prevalence to be moderate to high.The findings reflect the 4 in One Combo Test Kit's robust performance across different age groups and varying viral loads, reinforcing their reliability in everyday clinical practice.
