Common pregnancy test mistakes to avoid
Pregnancy tests are among the most commonly used diagnostic tools, offering a quick and reliable way to detect early pregnancy. Whether you are using a test strip, cassette, or midstream test, understanding how to interpret the results accurately is essential for peace of mind and informed next steps.
At Access Diagnostics we supply high-quality pregnancy tests trusted by healthcare professionals and individuals across the UK. This guide is designed to help you read and understand your pregnancy test results with confidence.
How Do Pregnancy Tests Work?
Pregnancy tests detect the hormone hCG (human chorionic gonadotropin), which begins to be produced shortly after a fertilised egg implants in the uterus. Most tests can detect hCG from the first day of a missed period, though some highly sensitive tests can work a few days earlier.
Types of Pregnancy Tests
At ADTUK, we supply a range of pregnancy testing options, including:
- Midstream Pregnancy Tests – Simple to use with no additional equipment required.
- Cassette Tests – Require a dropper and urine sample; commonly used in clinical settings.
- Strip Tests – A cost-effective option, ideal for bulk testing and professional use.
Each test includes a control line (C) to confirm the test is working and a test line (T) to indicate pregnancy.
How to Interpret the Results
Positive Result
Two lines appear: one in the control (C) region and one in the test (T) region.
Even if the test line is faint, it is usually an indication of a positive result. A line in the test area should be considered positive if it appears within the timeframe specified in the instructions (typically 3–5 minutes).
Negative Result
Only the control (C) line appears, and there is no visible line in the test (T) region.
This result indicates that hCG has not been detected. If testing before your missed period, consider retesting in a few days, as hormone levels may still be too low to detect.
Invalid Result
No lines appear, or only the test (T) line is visible without a control (C) line.
This result means the test has not worked correctly and should be repeated with a new test kit. Causes may include insufficient urine, incorrect usage, or a faulty test.
When Is the Best Time to Test?
The first urine of the morning usually contains the highest concentration of hCG and is the most reliable for early testing. Testing too early can result in a false negative, so it is advisable to wait until at least the first day of your missed period for the most accurate results.
Common Mistakes to Avoid
- Reading the result too early or too late – always check within the recommended time window.
- Using diluted urine – avoid excessive fluid intake before testing.
- Not following the instructions – ensure all steps are followed carefully for accurate results.
Next Steps After a Positive Result
If you receive a positive result, it is important to confirm it with a healthcare professional. Contact your GP or midwife to schedule a prenatal appointment. Begin following appropriate health guidance, including taking prenatal vitamins and avoiding alcohol or tobacco.
