Yes I agree there may be a few invalid sticks in a pack of 50 but that is not such an issue with me, as they do not cost much and I still feel I get my money's worth with 50 sticks for such a low price. I have often had 2 lines show up clearly (not every month) but again I think this is to do with whether ovulation has occurred not whether there is anything wrong with the product. Many women make the mistake of thinking they are guaranteed to ovulate every month, but this is not the case. There are various months some women do not ovulate regularly and if this is the case, the sticks would not show up two lines. Review: The instructions are clear and easy and since NZ only seems to have the very ... - These work really well for me. The instructions are clear and easy and since NZ only seems to have the very expensive OPKs, this is a Godsend. I usually use a small yogurt pot for urine that I washed out before with some soap (no need for it to be sterile), hold the strip in the urine for about 30 sec, wait 10 mins to see the result. I have very unpredictable cycles, so since these are inexpensive I don't have to worry about how many I use. Mine get gradually stronger and when the test line is stronger/darker than the control, it's a positive. Easy! ## Features - PREDICT OVULATION WITH PRECISION: Our One Step Ovulation Test Strip is a fast and accurate way to find out when you're about to ovulate, which is the best time to conceive. It detects hLH surges in your urine, indicating that ovulation will likely happen within the next 24-36 hours. These strips can be an essential part of your ovulation & fertility test kits - EASY-TO-USE, NO HASSLE: This ovulation kit for women is easy to use. Simply dip the ovulation test strips into your urine sample. No complicated steps. It's 2.5mm wide, making it convenient for you to handle at home. This ovulation test kit ensures simplicity and reliability - SEE THE RESULTS CLEARLY: When hLH is present in your urine, a unique red line appears on the ovulation sticks. The line's darkness varies based on the concentration of hLH. This gives you a clear visual signal that ovulation is on the way. These ovulation kits are designed to make interpreting results straightforward - CONFIRMATION FOR PEACE OF MIND: Our fertility test kit for women includes a control line with labelled antibodies. When you see this line, you can be sure you've used the test strip correctly and that it's working as it should - BUILT-IN CONTROL LINE: We use a method called "immunochromatography" to make these ovulation tests reliable. It's a proven way to ensure that you get accurate results when you're trying to predict your ovulation and plan for your family's future ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004EYH8VM | | ASIN | B004EYH8VM | | Best Sellers Rank | 72,314 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 64 in Ovulation & Fertility Test Kits | | Brand | One Step | | Country of origin | China | | Country of origin | China | | Customer Reviews | 3.9 3.9 out of 5 stars (399) | | Customer reviews | 3.9 3.9 out of 5 stars (399) | | Date First Available | 3 Dec. 2010 | | Is discontinued by manufacturer | No | | Manufacturer | AiDe | | Manufacturer reference | OVSTR_T | | Product Dimensions | 16 x 2 x 15 cm; 58.97 g | | Units | 50.00 Count | ## Product Details - **Brand:** One Step - **Number of pieces:** 50 - **Special feature:** Accurate - **Specific uses for product:** Ovulation Test - **Test type:** ["munoass"] ## Images ![One Step: 50 Ovulation Test Strips - Highly Sensitive Fertility Tests - 20miu/ml Testing Kits - Image 1](https://m.media-amazon.com/images/I/710jp3KN5AL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ cheap and cheerful item. *by M***B on 24 January 2014* I've spent a lot of money on clear blue fertility monitors etc and this item does the job just as well.

The instructions are clear and easy and since NZ only seems to have the very expensive OPKs, this is a Godsend. I usually use a small yogurt pot for urine that I washed out before with some soap (no need for it to be sterile), hold the strip in the urine for about 30 sec, wait 10 mins to see the result.

Easy! ### ⭐ PLEASE READ- WARNING DON’T BUY *by A***H on 20 October 2020* WARNING DON’T BUY- PLEASE READ This product deserves absolutely NO stars. As others have pointed out, the lines are incredibly faint and IMPOSSIBLE to read. I am very upset as this has made my trying to conceive journey so much HARDER & STRESSFUL. I have been trying to conceive for more than a year and I buy ovulation tests to track ovulation. But these are useless and you can’t track anything with them. I have attached 2 pictures- one has 2 tests in it from a different seller and shows how these tests should be and how they mostly are from other sellers- very dark lines and easy to read. The other picture with the lot number as shown: 2-L06010-20 are the tests i bought from this seller. I emailed the seller and also attached the two pictures but they were adamant that they have tested this batch and that the batch passes their so called ‘threshold’. So in their opinion it’s fine- even though they’ve seen the other picture from another seller. I doubt these would pass the ‘threshold’ of a U.K. company, I don’t know where these people are based but would not expect this from a U.K. company. They do not want to give me a refund as I asked. If they did this then they would have at least one redeeming feature as a company. They are taking advantage of vulnerable people who may want to start a family or track their ovulation health- by selling worthless products. I want to take this to the small claims court. ## Frequently Bought Together - One Step: 50 Ovulation Test Strips - Highly Sensitive Fertility Tests - 20miu/ml Testing Kits - One Step: 50 x Ultra Early - 10mIU Wide Width Pregnancy Test Strips (Tests up to 6 Days Earlier) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/58362752-one-step-50-ovulation-test-strips-highly-sensitive-fertility-tests](https://www.desertcart.co.uk/products/58362752-one-step-50-ovulation-test-strips-highly-sensitive-fertility-tests) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-23*
