Product Description

Size: 2.5mm

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. Negative (not pregnant): Only one color band appears, in the Control Zone. No apparent band on the Test Zone. This indicates that no pregnancy has been detected. Positive (pregnant): Distinct color bands appear in the Control and Test Zones. It indicates that you are pregnant. The color intensity of the test bands may vary since different stages of pregnancy have different concentrations of HCG hormone.

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! I took a test after having my blood taken by the doctor and doing a urine test at the doctor's office. My HCG level was around 20 and the urine test at the doctor's office came up negative. But this test came up as a positive! It wasn't until my levels were below 20 did this test read negative! That's amazing. So I will be using them as we try again and will feel confident that they will give me a early result. Great product!
The only trick with these is that they are not mid-stream tests. They are simply little test strips (they are the size of dipsticks that you test your urine with at the doctor's office for various things). So you must pee into a cup (I used the tiny throw-away bathroom sized "Solo" cups) and dip the stick up to a line that is marked on the strip. I saw results within minutes. Each strip is individually wrapped.

These strips can detect pregnancy before a missed period but potential buyers should be aware that the line takes longer to appear and is much fainter than the line you will get with one of the packaged drugstore brands. In fact, I took this test before my missed period and thought that the results were "inconclusive" because the line was barely visible so my husband went out to get a drugstore test. That test was much more obvious and results appeared much quicker. Even now, about a week plus after my period, the line is still fainter than the control line and takes a couple of minutes to appear. Hopefully that doesn't indicate a problem. Anyway, the bottom line is that if you plan on taking a lot of pregnancy tests, these are a good option just don't expect them to work the same as the other tests you may be used to taking.

UPDATE: It turned out that the pregnancy for which I originally reviewed these strips miscarried at 6.5 weeks :( This is perhaps why the line was so faint and took so long to appear. I used these again when I became pregnant in January 2011 and the line was strong and appeared quickly. Now I am 23 weeks pregnant.

After a rather depressing whirlwind in March with just about every store brand known to man, where I got faint positives from 8 dpo to 10 dpo on lots of different non-digital tests... the faint lines never got stronger, and went away by 11 dpo. I'd ordered some of these, they showed up at 12 dpo and showed a clear, no-squint negative faster than I've ever seen a pregnancy test "clear"... and I got my period a few hours later.

For me, the negatives being clear and rapid is almost as important as whether the positives are early or not. Early conceptions don't always stick around, they estimate that half of eggs that fertilize never come to term, and most people never know it because they're not insane POAS-aholics.

Since I am, I decided I needed a cheaper "front end" test. With these, I can test every day if I want, or even a couple times a day, and I'm pretty confident in my result. I would never trust a single positive test anyway... because I've lost enough pregnancies to not assume that a positive test means a baby at the other end. So what I need are tests that I can use, and watch to see if they get darker.

The price is unbelievable. Dipsticks are my preference, I tend to pee in a cup even for the midstream tests, it's far tidier. It helps if you've got good control, and can pee a little, pee in the cup, stop before it overflows, then finish your business after you've pulled the cup away. This isn't hard for me at all, and if you're going to be seeing a doctor for pregnancy, you've got to get the hang of peeing in a cup anyway, they make pregnant women do it all the time.

For speed, these cannot be beat. Every other test says, "Dip for 5 (or 10, or 20) seconds, then lay flat, read between 5 and 10 minutes.

So disappointing, I would not purchase these again. After being a week late, I am still getting negatives with these but positives with all other tests. I went several days thinking the negatives were correct and yet I felt pregnant. Both early response and regular tests showed positive right away.

I used the Wondfo tests to detect my pregnancy at 11 DPO. For the first solid minute, the test was completely negative which left me feeling discouraged. It did eventually start show a very faint but visible line by the 3-5 minute mark. I confirmed it on a First Response Early Result test with the same FMU and there was an even lighter test line on that brand. So, when it comes to detecting a very early positive, Wondfo SCORES! When it comes to the speed of detection, it's a very slow reacting test. So, being the test addict that I am and because I had about 20 tests left, I continued testing for the next week with the Wondfo tests. I wanted to see the line get darker and darker to confirm that my beta levels were rising. For the first 2-3 days, the line did get a little bit darker. Not by much, but enough to visually confirm that I was progressing slightly. But after about 3 days, the line never got any darker. Even at it's driest, darkest state, the test line is still much lighter than the control line. It also continued to take over 1 minute for the test line to even begin turning light pink. I was worried that something was wrong with ME, so I bought a FRER test again, and was pleased to see a very fast developing, dark test line at 17 DPO. MUCH darker than that first test I had taken a week ago and it came up instantly. That's what I'm talking about!

Even tonight, at 5 weeks 1 day, I took another Wondfo test for kicks and at 1 minute you would have thought it was completely negative and at the 3 minute mark, it's a real squinter. After the test has completely dried, the line is still much lighter than the control line.

So for those of you wanting to detect a very early pregnancy for very little cost, this test is awesome!
