 5 Ovulation Test Strips and 5 Pregnancy Test Strips: Free Shipping  



Pregnancy Test Strip-FDA Approved

One Step HCG Urine Test is a rapid pregnancy test, which you can easily carry out yourself. It detects the presence of human chorionic gonadotropin (“HCG”), which appears in urine very early during pregnancy.



Human chorionic gonadotropin (hCG) is a hormone, produced by the developing placenta shortly after the conception and secreted into the urine. The pregnancy test contains antibodies which specifically react with this hormone.


To use the test strip, simply fill a container with urine and dip the test strip in the container in a vertical position. Your results appear within five minutes. This test is capable of detecting human chorionic gonadotropin or hCG (a hormone present in women's urine during pregnancy) at levels of just 15 mIU/ml/hCG. That means you can begin testing accurately as early as six to eight days after conception - well before your first missed period!

If you are fertility charting, and you know your ovulation date, you may begin testing as early as 7-10 DPO (days past ovulation) when the hCG level in urine will, on average, reach 15 mIU/ml. We recommend using a first-morning urine sample as this will contain the highest concentration of hCG.

Ovulation Test Strip-FDA Approved

One Step Ovulation Urine Test is a qualitative test used to predict when there is a LH surge, and in turn, when you are likely to ovulate. Experts state that LH testing is a reliable way to detect ovulation. Ovulation will occur after 24-48 hours following a positive test.



The length of the menstrual cycle is the duration from your first menstrual bleeding day to the day before the next bleeding begins. Determine the length of menstrual cycle before test. Please refer to the chart below to determine when you should start testing. If your cycle is shorter than 21 days or longer than 38 days, consult a physician. If you do not know your cycle length, you may begin the test 11 days after your first period since the average cycle length is 28 days. Perform 1 test each day over a 5 days period, or until the LH surge has been detected.


If you're trying to conceive, One StepTest offers low-cost, high sensitivity ovulation predictor strips.  Test strips are placed vertically in a container of urine. Both tests provide accurate results in just minutes, allowing you to predict peak fertility.

Ovulation predictor tests work by allowing you to detect your monthly LH Surge - the sudden and dramatic increase in luteinizing hormone present in your urine just before you ovulate. Lh is the hormone that facilitates ovulation (the release of the egg). When you detect your LH surge with an ovulation test, you know you are fertile!

Since the best time for fertilization of the egg to occur is within 6 to 24 hours after you ovulate, correctly gauging your body's cycle is extremely helpful in increasing your chances of becoming pregnant. Our ovulation tests detect LH with a sensitivity of 10mIU/ml/lh - and all of our tests are brand new, with an expiry date of 2 years!
