A positive pregnancy test can bring joy or shock. But what if it’s wrong? False positive pregnancy tests do happen. Understanding why helps you get accurate results.
What Is a False Positive?
A false positive means the test shows you’re pregnant when you’re not. It’s rare, but it happens. The test detects a hormone that shouldn’t be there. Or it misreads the result line.
Most pregnancy tests are very accurate. They work about 99 per cent of the time. But nothing is perfect. Knowing the causes helps you trust your result.
Medication Can Cause False Positives
Some medicines contain hormones. These hormones mimic pregnancy hormones. Fertility drugs are the main culprit. If you take these drugs, tell your doctor before testing.
Certain other medications can also affect results. These include some cancer treatments. Always check your medicine packet. Ask your pharmacist if you’re unsure.
Medical Conditions Matter Too
Some health conditions raise hormone levels. Ovarian cysts can do this. So can certain cancers. These aren’t common causes, but they happen.
Menopause can also confuse tests. Hormones change during menopause. This might trigger a false positive. A blood test from your GP gives you the real answer.
Testing Too Early Is Common
Timing is everything with pregnancy tests. Test too early and you might get a false negative. But early testing can sometimes show false positives too.

hCG Levels Tell the Story
Pregnancy tests look for hCG hormone. This hormone only appears when you’re pregnant. But levels matter. Very low levels might cause confusion.
Understanding hCG Levels in Early Pregnancy explains what these levels mean. The hormone doubles every few days early on. A blood test measures exact levels. Your GP can do this test.
User Error Can Happen
How you use the test matters. Reading the result at the wrong time causes mistakes. Most tests have a time window. Check your test after the right time has passed.
Wet tests can give wrong results too. Keep your hands dry. Don’t touch the test tip. Follow the instructions carefully.
How to Read Pregnancy Test Results Correctly guides you through this. Knowing how to read your specific test prevents confusion. Different tests show results differently.
Old Tests Can Be Unreliable
Pregnancy tests expire. Old tests might not work properly. Check the date on the box. Use fresh tests for accuracy.
Store tests correctly too. Keep them dry and cool. Damp or warm storage damages them. A damaged test gives unreliable results.
Getting Better Answers
Digital tests remove the guesswork. They show “Pregnant” or “Not Pregnant” in words. No lines to misinterpret. The Clearblue Digital Pregnancy Test with Weeks Indicator also tells you how many weeks.
Still worried? A blood test is always the answer. Your GP can do this. Blood tests are more precise than home tests. They measure exact hCG levels.
Final Thoughts
False positives are uncommon. But they do happen. Medicines and medical conditions are the usual reasons. Testing at the right time helps. Using tests correctly matters too.
If you’re concerned about your result, see your doctor. A simple blood test confirms pregnancy. That gives you peace of mind. You’ll know the true answer.
