False positive test – what do erroneous results cost the healthcare system?
A false positive test is not just an inaccurate measurement – it is a result with consequences. As rapid tests and self‑tests become more widespread, it is crucial that healthcare professionals, pharmacies and NGOs demand quality. Because what is the cost when a test result creates unnecessary anxiety and leads to incorrect treatment?
What is a false positive test?
A false positive test indicates that a patient is infected – even though they are not. This may be due to low test quality, cross-reactions with other infections, or insufficient validation. The result is the same: unnecessary strain on both the individual and the healthcare system.
Why genuine test quality matters for pharmacies and NGOs
False positive test results are particularly problematic in settings where follow-up is not always possible. NGOs, mobile testing clinics and pharmacies are often the first point of contact for citizens. A test with low specificity can create uncertainty, overtreatment and loss of trust.
Example: NGO initiative using low-quality tests
An NGO distributes rapid tests in vulnerable environments. The test shows a high rate of positive results, but many are false. This leads to worried enquiries, unnecessary consultations and loss of credibility. After switching to a test with documented accuracy, the number of false alarms drops significantly.
Pharmacies and their responsibilities
Pharmacies that sell rapid tests for private use are in a special position. When a test shows a positive result, it can trigger severe anxiety. If the quality of the test has not been validated, it can create misunderstandings and extra workload for pharmacists and healthcare staff.
What should you look for when choosing a test?
- CE marking and clear documentation of test performance
- The test’s ability to distinguish between past and active infection
- The manufacturer’s transparency regarding sensitivity and specificity
- Independent clinical studies rather than marketing-based reviews
Debate: Is a cheap test a false economy?
Several test products on the market are promoted with low prices and big promises. But behind these offers there are often tests with incomplete documentation or low clinical accuracy. As syphilis and herpes become more widespread, it is important that purchasers assess the product’s real value – and the consequences of incorrect results.
