Wondfo Pregnancy Test strips are incredibly cheap, but are they accurate? You’ll read it here in our extensive review.
On Amazon, you will immediately note how popular the Wondfo Pregnancy Test Strips are. They come in packs of 25 or 50 strips and are one of the cheapest pregnancy tests available. Is it a smart idea to buy such a cheap test for such an important thing as finding out whether you are pregnant? Or does it really not matter since all tests are based on the same methodology and are other brands just overcharging for their tests? Does Wondfo actually offer a reliable test at a low pricepoint? Let’s find out in this extensive review.
Description of the Wondfo Pregnancy Test Strips
Let’s start out with looking at what the company itself has to say about their test. The information on their website is scarce, but at least they mention:
“Wondfo One Step hCG Pregnancy Urine Test is a rapid pregnancy test. It adopts double antibody sandwich method detects the presence of human chorionic gonadotropin (hCG), which appears in urine very early during pregnancy.”
A rapid test. Sounds good. We want to have our result quickly don’t we? And the double antibody sandwich method definitely sounds like the test is quite sophisticated. Or is it?
Regardless of the technical language, this test works just like most other pregnancy tests out there. It measures the levels of the pregnancy hormone human chorionic gonadotropin (hCG) in your urine. This hormone is produced by the cells of the embryo that will later form the placenta. The level of hCG starts to increase from its basal level of less than 5 mIU/ml directly after implantation, and doubles about each 48 hours during the first weeks of pregnancy.
Now, let’s look at the features of the Wondfo Pregnancy Test Strips, as advertised by the manufacturer:
Early detection of pregnancy as early as 7 days after the fertilized egg implantation.
- Simple to use.
- A variety of design specifications suitable for self-testing use and for professional use.
- Results in 3 to 5 minutes.
- Store in room temperature.
- 24 months shelf life.
- Sensitivity: 25 mIU/ml.
Wondfo claims that pregnancy can be detected as early as 7 days after implantation. However, they do not support this claim by a reference to a clinical study. We just have to take their word for it.
On the other hand, if we assume that the claimed sensitivity (25 mIU/ml) is correct, it means that the test has indeed a reasonably good sensitivity around 7 days after implantation, as the average level of hCG after 7 days is around 100 mUI/ml.
Let’s say that the test can measure pregnancy hormones at such low levels and that it gives a positive result 7 days after implantation. Implantation of a fertilized egg normally takes place 6-12 days after ovulation. So actually, 7 days after implantation can be anywhere between 13-19 days after ovulation. This is roughly at the time of your missed period!
Now, it may be that the test is reasonably reliable a few days earlier, but honestly, based on the information provided by the manufacturer, we have nothing to support this.
Using the test
Unlike some of the other pregnancy tests on the market, such as the First Response Early Pregnancy Test, that can be held in your urine stream, the Wondfo Pregnancy Test requires you to collect your urine in a cup. The test strip can then be immersed and the result should be read after 5 minutes. The image below shows how you do the test.
With so little information from the manufacturer, we can take a look at what user’s say about the test. Given the large number of reviews on Amazon for the Wondfo Pregnancy Test Strips, it is clear that these tests are highly popular. The majority of buyers give the test a 5-star rating. Sarah writes:
“Accurate and Cheap!”
“I wish I had known about these sooner! I have been TTC for a year and have purchased expensive tests at the drug store the entire time. But after suffering a miscarriage and knowing that I would start testing again, I found these! I received them right after my miscarriage and used them to check my beta levels to make sure they were dropping properly. I would rate these tests as extremely sensitive!”
C. Greene from Long Island says:
“Why spend more?”
“These worked great for me – I started testing early (you can waste these as they are so cheap) and the day I finally tested positive I used 5 just to be sure (and double-checked with a more expensive model). Definitely get these.”
That last comment summarizes what may be the best thing about these tests. They are very cheap tests compared to the competitors. The manufacturer claims a sensitivity equal to other early pregnancy tests, such as the First Response Early Pregnancy test. Based on user reviews, this seems to be correct. The majority of women are very happy with the tests. So, because you get many sticks when you buy the Wondfo pregrancy test, you can do several tests if the first gives a negative result and you still think you could be pregnant.
The Wondfo Pregnancy Test strips are available on Amazon for cheap. Because prices vary all the time, I recommend you to check out the current price yourself here. Amazon offers free shipping within the US and delivery is usually within 2 business days.
If you are trying to conceive and are looking for a bunch of cheap pregnancy tests, the Wondfo Pregnancy Test Strips are just right for you. Buyers on Amazon are really happy with the tests and you will save a lot of money compared with when you buy a pregnancy test at your local drug store. You should be aware that these are not mid-stream sticks, so you cannot just hold them in you urine stream but have to use a cup to collect your urine.
You should always consider the possibility that pregnancy test results are incorrect, and this possibility is more likely the earlier you take the test. In the end, you should always consult with your physician to confirm the outcome of a home pregnancy test.
