As the COVID-19 virus continues to morph into various forms — including the XBB.1.5 variant or the "Kraken" as some are calling it — staying on top of testing strategies is more essential than ever. At General Biologicals Corporation (GBC), we understand the importance of continuous research and timely updates for our COVID-19 Ag Rapid Test. So, let's delve into the latest updates.


Update 1: GB COVID-19 Ag Rapid Test Efficacy on the Latest Variant

Good news for the future: our research scientists have confirmed the efficacy of the GB COVID-19 Ag Rapid Test in detecting the OMICRON variant and its sub-variants, including the XBB.1.5 or “Kraken” variant.

The success of our test is anchored in its design. Our Ag Rapid Test primarily targets the N-protein of the virus, not the S-protein, also known as the spike gene. This distinction is key as OMICRON and its sub-variants contain mutations primarily in the spike protein, leaving the N-protein intact. Therefore, our test remains effective, even with the new strain changes.

Update 2: The Importance of Regular Testing
One of the major perks of the GB COVID-19 Ag Rapid Test is its ease of use, as it has been designed with the at-home user in mind. As the virus continues to evolve and variants surge, it is recommended to test frequently — ideally once, and then again in 48 hours. This two-step approach is a solid strategy in combating the spread of the virus, particularly with the constantly evolving variants.

The process is straightforward. If the test returns a positive result, it is confirmed — you're considered positive. However, if the initial test is negative, we recommend retesting within 48 hours. If the second test is also negative, continue testing every 48 hours.

The frequent testing approach helps increase the accuracy of results, ensuring that infections are caught in their early stages. The faster we detect, the quicker we can isolate and prevent further spread. This proactive approach is an integral part of managing the ongoing pandemic.

The CDC also recommends self-testing for people with signs and symptoms of COVID-19, as well as for those who have had a recent known or suspected exposure to the virus.

Recognizing Symptoms of the 'Kraken' Variant
As we continue to learn about the COVID-19 virus, it's essential to be aware of the symptoms associated with each new variant that emerges. The Kraken variant, or XBB.1.5, is no exception.

● Fever and Chills
● Persistent Cough
● Fatigue
● Loss of Taste and Smell
● Breathing Difficulties
● Gastrointestinal Issues
● Headaches and Body Aches

Please note, these symptoms are similar to those of other variants and even other illnesses. If you experience any of these symptoms, it doesn't necessarily mean you have the Kraken variant. However, given the prevalence of COVID-19, it is crucial to get tested if you exhibit any of these symptoms, particularly if you've been in contact with someone who has tested positive.

The World Health Organization (WHO) also provides a comprehensive list of symptoms associated with COVID-19 and recommends that anyone experiencing severe symptoms, such as difficulty breathing, seek medical attention immediately.

Living with COVID-19: A Look into the Future
It's become clear that COVID-19 and its variants will be part of our lives for the foreseeable future. While we can't predict the exact impact of future variants on fatality trends, we can prepare ourselves by following best practices. Regular testing is a significant part of that plan.

We recommend having a stock of GB COVID-19 Ag Rapid Tests at home for frequent testing as needed. It's always better to have tests readily available, especially in situations where prompt testing is crucial. It's about staying prepared, vigilant, and proactive in the face of this ongoing pandemic.

Continuous Research and Development
At GB, we remain committed to our goal of fighting the COVID-19 pandemic effectively. We're investing continuously in our research and development to ensure our tests are up-to-date and relevant. Our team of scientists is always monitoring new strains of the virus to confirm the effectiveness of our test kits.

As more information about the virus and its variants become available, we will continue to provide updates about our COVID-19 Ag Rapid Test. We're in this together, navigating through the complexities of the pandemic, and adapting as needed.

The Future: Staying One Step Ahead
Looking forward, our goal is to stay ahead of the curve. The rapid evolution of the virus makes the future uncertain. However, one thing is clear: the need for dependable, easy-to-use testing will remain. As the virus continues to change, our testing strategies and technologies must also adapt.

That’s why we're dedicated to continuous research and improvement. We're committed to maintaining the GB COVID-19 Ag Rapid Test as a reliable, user-friendly solution that keeps up with the ever-evolving nature of the COVID-19 virus.

As we face the realities of living with COVID-19 and its variants, the GB COVID-19 Ag Rapid Test will continue to be a vital tool in our shared fight against the pandemic. We're here to keep you informed, equipped, and prepared in these challenging times.
