Lateral Flow Tests

When to book a lateral flow test

Come in for a rapid test if:

• You have symptoms of COVID-19, flu or a throat infection and want a quick answer
• You need a result for international travel or an event
• You have been in close contact with someone who tested positive
• Your workplace or school requires regular testing
• You want to check your status before visiting someone vulnerable
• You need a test certificate for official or professional purposes

Tests available

• COVID-19 lateral flow tests - rapid antigen tests detecting active infection
• Flu lateral flow tests - detect influenza A and B, guiding antiviral treatment decisions
• Strep A tests - for streptococcal throat infection, helping decide whether antibiotics are needed
• Combined COVID-19 and flu tests - both viruses from a single sample

What are lateral flow tests?

Lateral flow tests, also called rapid antigen tests, detect proteins associated with an infection. A nasal or throat swab is applied to a test strip containing antibodies that react with the target substance, and a visible line appears within 15 to 30 minutes if the result is positive.

They are less sensitive than laboratory PCR tests but far faster. Accuracy is highest in people with symptoms, and specificity is high, so a positive result is very likely to be genuine. A negative result with ongoing symptoms may need further testing, and our pharmacists can advise.

Understanding your result

• Positive (two lines) - infection detected. We advise on treatment, isolation and next steps
• Negative (one line) - no infection detected at this time. If symptoms persist, further testing or a GP consultation may be recommended
• Invalid (no lines or unclear) - the test has not worked and must be repeated with a new kit

Testing for travel and the workplace

Some countries still require proof of a negative COVID-19 test. We provide supervised tests with official certificates that meet international travel requirements, so check your destination's rules in advance and book within the required testing window.

Supervised testing also carries more weight than self-administered kits for employers and travel authorities. Incorrect swabbing is one of the most common causes of a false negative at home, and a pharmacist-taken swab significantly improves accuracy. We can also support workplace testing programmes with bulk kit supply and guidance on protocols.
