From the Zoom Baby Archive: This review covers Wilko Pregnancy Test Strips as they were sold by the original Wilko retail business. The former Wilko store network closed after the company entered administration in 2023, although the Wilko brand was subsequently acquired by CDS Superstores and has since returned online and through a smaller number of new stores. The Wilko Pregnancy Test Strips reviewed here are no longer part of Wilko’s current pregnancy-test range. Prices and product specifications below are therefore retained as a historical record. For current fertility and pregnancy guidance, please see our latest articles.
When we originally reviewed this product, Wilko was a familiar British high-street chain selling household goods and homewares at good-value prices. The retailer also offered a limited range of healthcare products, including fertility and pregnancy products. In this review we looked at the pros and cons of using Wilko Pregnancy Test Strips.
Wilko Pregnancy Test Strips
First impressions of this product were good, as the packaging was attractive. One box of Wilko Pregnancy Test Strips contained three individually wrapped pregnancy test strips. There was also a comprehensive instruction leaflet in the box.
2022 Wilko Pregnancy Test Prices
When we last updated the prices in 2022, a box of Wilko Pregnancy Test Strips cost £1.55. This worked out at nearly 52p per strip, which represented good value at the time. The price had increased by 10p per pack from when we first wrote this review in 2019.
For comparison, at the time a pack of five Boots Pregnancy Test Strips cost £4.99, which was nearly £1 per test.
Wilko Pregnancy Test Strips were also available through the Wilko website at the same £1.55 price. These prices and the delivery charges quoted in the original article are now historical, and the Wilko-branded pregnancy test strips are no longer listed in the retailer’s current range.
Wilko also sold Pregnancy Test Sticks, which were the familiar midstream type of pregnancy test. We reviewed those separately.
If you are looking for pregnancy test strips today, Zoom Baby Pregnancy Test Strips are currently available in regular and ultra-early versions and in several different pack sizes.
20 mIU/ml Sensitivity
Pregnancy test strips are designed to detect human chorionic gonadotrophin (hCG) in urine. The Wilko Pregnancy Test Strips we reviewed stated a sensitivity of 20 mIU/ml hCG.
For comparison, Zoom Baby currently offers regular pregnancy test strips designed to detect hCG at 25 mIU/ml and ultra-early pregnancy test strips with a stated sensitivity of 10 mIU/ml. A lower detection threshold means a test is designed to detect a lower concentration of hCG, but this should not be interpreted as a guarantee that pregnancy will be detected a particular number of days earlier.
The NHS advises that most pregnancy tests can be used from the first day of a missed period, although some more sensitive tests can be used earlier. Testing too early can result in a negative result even when you are pregnant, so always follow the instructions supplied with the particular test you are using.
The 2.5 mm Wide Test Strips
One feature of the Wilko Pregnancy Test Strips that we did not particularly like was their width. The strips we examined were only 2.5 mm wide.
In our hands-on assessment, we found the narrow strip less convenient when reading and interpreting the result and preferred the wider 3.5 mm strips that Zoom Baby supplied. This was an ease-of-use judgement rather than an indication that a 2.5 mm strip was inherently inaccurate.
The accuracy of a home pregnancy test depends on factors including the performance of the individual test, following its instructions correctly and when the test is taken. Taking a pregnancy test too early can increase the chance of receiving a negative result when hCG has not yet risen sufficiently to be detected.
In Conclusion
We liked the packaging and instructions supplied with the Wilko Pregnancy Test Strips. The £1.55 price recorded in 2022 was also very competitive compared with many other high-street pregnancy tests available at the time.
Our main reservation was the narrow 2.5 mm strip. During our original hands-on assessment we preferred wider strips because we found them easier to handle and interpret. That remains a reasonable usability preference, but strip width on its own should not be treated as a measure of a pregnancy test’s accuracy or reliability.
The Wilko Pregnancy Test Strips reviewed here are no longer available from Wilko, so this article should not be regarded as a current product recommendation. If you prefer the dip-strip format, Zoom Baby currently offers regular pregnancy test strips with a stated sensitivity of 25 mIU/ml and ultra-early pregnancy test strips with a stated sensitivity of 10 mIU/ml.
