Are you one sneeze away from a health crisis? Just when you thought you had every rapid antigen test in your medicine cabinet, a new hybrid has appeared on the pharmacy shelves: the 3-in-1 self-test kit that can detect not only COVID-19 but also influenza A and B.

Why Know Your Virus? It’s Not Just About Feeling Crummy!

You might wonder why it matters if you have influenza A or B. Isn't it enough to down some paracetamol, call in sick, and hope for the best? Wrong! Understanding whether you're dealing with the flu or COVID-19 can influence your treatment and recovery.

Understanding Influenza: A vs. B vs. COVID-19

Here’s the scoop: there are four types of influenza viruses—A, B, C, and D. However, types C and D are less concerning, primarily causing mild symptoms and affecting cattle, respectively. Professor Paul Tambyah from the National University of Singapore explains that influenza A poses the greater threat, often leading to serious complications like pneumonia and being responsible for flu pandemics.

In Singapore, influenza A is more commonly detected, accounting for 78% of cases in July. But influenza B isn't far behind, constituting 12%. The flu seasons in tropical climates like Singapore are complex, featuring multiple peaks throughout the year, unlike the predictable winter flu seasons in temperate regions.

Why Distinguishing Between the Viruses Matters

Spotting the difference between influenza and COVID-19 is crucial for getting the right treatment. Associate Professor Barnaby Young points out that while Oseltamivir can treat both influenza strains, Paxlovid is specifically for COVID-19. Quick identification can aid recovery and keep vulnerable populations like the elderly safe.

In-Clinic Tests vs. 3-in-1 Self-Test Kits

Why weren’t you tested at your doctor’s office before? In-clinic tests can be costly and time-consuming, often leading to the simple prescription of over-the-counter medications for symptom relief instead. This is where 3-in-1 self-test kits prove invaluable—offering fast results from the comfort of your home.

Decoding the 3-in-1 Self-Test Kits

These hybrid kits operate like traditional rapid antigen tests but cover three viruses. Users can expect a clear line indicating infection if any virus is present. However, be cautious: while a positive result is reliable, a negative one requires careful interpretation as it doesn’t rule out infections from other viruses.

What to Do If You Test Negative

Regardless of your test outcome, maintaining health precautions is essential—avoid crowds, wear masks, and consider taking time off if symptom-ridden. Local options include various brands, and even a unique kit currently under trial by Singapore’s Cellbae.
