10 Most Sensitive Pregnancy Tests in the UK

Accurate and sensitive Pregnancy tests are necessary for early and accurate diagnosis. For precise results, it is advised to test for pregnancy roughly ten days after conception or 1-4 days before the expected period. By this time, the level of human chorionic gonadotropin (hCG), the hormone in the urine that most pregnancy tests measure, is close to 25 mIU/mL. 

It is the threshold level for most pregnancy tests. This hormone is highly concentrated in the urine early in the morning, so taking the test early in the morning is necessary. There is a risk of false negative results if there is early pregnancy or if the test is taken in the evening. 

We analysed the pregnancy tests on the market and selected the top 17 tests. We then narrowed our choice to 10 easy-to-read, sensitive, and accurate tests that work well before the expected period. The gynaecologist/ obstetrician on our team reviewed this article for scientific and medical accuracy and focused on the early timing, accuracy, and other requirements of effective pregnancy tests. 

Here are our top 10 most sensitive pregnancy tests, which are needed by all concerned people and are top-ranked by our professionals.

Frequently Asked Questions 

What is the sensitivity of most of the pregnancy tests in the first response? 

Most first-response pregnancy tests have an analytical threshold of 6.3 mIU/mL and can accurately detect more than 95% of pregnancies. Some tests go as low as 5.5 mIU/mL. Levels less than five mIU/mL are considered negative. 

Which is the most accurate hCG test? 

Blood tests are much more sensitive than urine tests and can accurately detect more than 99% of pregnancies. For example, the Clearblue Pregnancy Test is over 99% accurate, and it can detect the pregnancy well over time and earlier than many other tests.

What is the sensitivity of the cheap pregnancy tests? 

Although cheap tests are sometimes much less sensitive than many other expensive tests, the results of many cheap pregnancy tests are still 99% if used according to the manufacturer's recommendations. 

What is the maximum possible delay in the pregnancy in case of non-pregnancy? 

If no other condition affects pregnancy, periods typically start within 24-38 days of the last period, depending upon the length of the usual cycle. Late or missed periods are considered if they are at least seven days past the expected date. 

What are the pregnancy tests that are recommended by most of the doctors? 

The doctors recommend both urine and blood pregnancy tests. The urine tests are far quicker than the blood tests, but both are over 99% accurate. 

Which pregnancy tests are useful for detecting pregnancy at the earliest time? 

Many pregnancy tests, such as the Clearblue Pregnancy Test and FIRST RESPONSE pregnancy tests, help detect the pregnancy much earlier than the other tests. The FIRST RESPONSE pregnancy tests help detect the pregnancy almost six days earlier than the day of the missed period.
