Viral or Bacterial? How At-Home PCR Testing Helps You Choose the Right Treatment

Are You Reaching for Antibiotics – But Not Sure You Need Them?

Many people in the UK reach out to their GP for antibiotics at the first sign of cough, trouble breathing, or a persistent sore throat. But most respiratory illnesses are caused by viruses that antibiotics won’t help.

How Can You Tell If Your Illness is Viral?

• A slow onset (starting with a tickle in the throat, then progressing to congestion, aches, and fatigue).
• Symptoms like cough, runny nose, or fever without thick green mucus are often due to viruses.
• NHS guidance recommends avoiding antibiotics except for bacterial infections.

What is a PCR Test and Why is it Different?

Our At-Home Viral Respiratory PCR Test Kit uses advanced technology to detect viral DNA in your throat and nose:

• Confirms which respiratory virus you’re fighting (flu, RSV, COVID, etc).
• Helps you avoid unnecessary antibiotic treatments.
• Can empower your GP to give you the best advice (or fit note for work).

Action Steps for Symptom Relief (Even Without a Test)

• Rest and avoid contact with vulnerable people.
• Take paracetamol or ibuprofen for fever and aches (if not contraindicated).
• Use salt water gargles to soothe throat irritation.
• Monitor your symptoms. If they worsen, seek help.

When is Testing a Good Idea?

• If you want to stop guessing and have a clear answer.
• If you're worried about transmission at work or home.
• To avoid unnecessary GP appointments for antibiotics.
