Pregnancy Test Buyer’s Guide

How do I know which pregnancy test is right for me?

Pregnancy Tests Buyer's GuideWhen it’s time to shop for pregnancy tests, you will notice that there are a number of factors to consider. How early is the test able to detect a pregnancy? How much does it cost? Is it easy to use? Should I buy the test strip or midstream format? The list goes on…
So, how do you know which pregnancy test is right for you? As with many things related to conception and pregnancy, we can learn from other women. We conducted a poll on our website to determine which features women value mostin a pregnancy test. Here are the results from the 8,848 responses we have received so far:

  • Earliest Possible Detection: 72%
  • Affordability: 24%
  • Ease of Use: 4%

As you can see, an overwhelming majority of participants in the poll (72% of respondents) consider the ability of a pregnancy test to detect to pregnancy early to be the most important factor when purchasing a test. Affordability was cited as the most important factor by 24% of respondents, while only 4% of respondents base their purchasing decision on ease of use. Below is some information to help you decide which type of pregnancy test is right for you.

Early Detection of Pregnancy: It is not surprising that early detection of pregnancy is forefront in the minds of trying to conceive women. If you suspect that you might be pregnant, you don’t want to wait around any longer than absolutely necessary to confirm it! Most pregnancy tests work by detecting the presence of the hormone called human chorionic gonadotropin (hCG) in urine. HCG is a hormone secreted by the developing placenta upon implantation of the fertilized egg into the uterine wall. Implantation typically occurs 6-10 days after conception. As the embryo grows, the amount of hCG increases rapidly. How quickly after conception a pregnancy test can detect a pregnancy is a function of its sensitivity to hCG, which is measured in thousandths of International Units and notated by the abbreviation mIU. The more sensitive the test is to hCG, the quicker it will be able to accurately test for pregnancy. A newly pregnant woman will have around 25 mIU of hCG at 10 days past ovulation, 50 mIU at 12 days past ovulation and 100 mIU at around two weeks past ovulation.
Many of the pregnancy tests that are available in drug stores detect hCG at the 50 mIU/ml or 100 mIU/ml level. Tests calibrated to the 50 mIU level can detect pregnancy as early as 12 days past ovulation, while those calibrated to 100 mIU will be able to detect pregnancy approximately two weeks past ovulation. At, we offer pregnancy tests (in test strip and midstream format, see below) that are calibrated to detect hCG at the 20 mIU/ml level. These tests can provide an accurate result as early as seven to 10 days after ovulation, well before you have missed your period.

Affordability: If you head for the corner drugstore to purchase a pregnancy test, you will likely spend between $6 and $10 for a midstream format pregnancy test calibrated to the 50 mIU/ml or 100 mIU/ml level. At, our pregnancy test strips are offered at less than a dollar each, and our midstream tests cost $2.25 each. The earliest detection test strips (10 mIU/ml) cost just over $1.00 each. Purchase your pregnancy tests online at and get the benefit of early detection at a fraction of the cost of drugstore prices.

Test Strip or Midstream Format: Pregnancy tests come in two formats: test strip or midstream. Determining which format is better is really just a matter of personal preference. Both types of tests are easy to use and to interpret, and both types are accurate at 99.9%. At, all of our tests come individually packaged in foil wrap to protect the test from damage or contamination. While both types of tests are popular among our customers, the test strip format tests are less expensive than the midstream format tests.

Ease of Use: Both the test strip format and midstream format tests are easy to use and produce quick results. The test strip format is the type of urine test you will most likely take at your doctor’s office. To use the test strip format, you collect a sample of urine in a small cup and dip the test strip vertically into the urine for a few seconds. Remove the test strip from the sample, lay it down flat on a dry, non-absorbent surface, and in 5 minutes your test results will appear. The appearance of one line indicates a negative result, while two lines indicate a positive result for pregnancy

To use the midstream format, remove the cap from the test, hold the test stick in your stream of urine for 7 seconds and then replace the cap. The results of the test will appear in 2 to 5 minutes. One line in the result window indicates a negative result; two lines indicate a positive result for pregnancy.

Width of Test Strip: If you decide to purchase the test strip format, it is important to note the width of the test strip. Thin test strips make interpretation of the test results difficult (and even more so when testing for early detection), as there is simply less of the test line to see. At, all of our pregnancy test strips are 5 mm wide (the maximum width available), which makes interpretation easier.

User Feedback: Perhaps the best way gauge the quality of a test is to read actual consumer feedback. We’ve received thousands of comments from customers over the years regarding our products. While not all of the feedback we receive is positive, the vast majority of our customers indicate that they’re pleased with the quality of our pregnancy testing products and would “definitely shop with again” for their preconception product needs.
