Product Description

Size: 25 Strips

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.

5.0 out of 5 stars Accurate AND Cheap April 18, 2009

By Sarah

Size Name:25 Strips|Amazon Verified Purchase

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.

4.0 out of 5 stars Works but line is fainter and takes longer to appear than on a drugstore test July 24, 2010

By nr danilow

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.

By Jennifer

These are more sensitive and WAY cheaper than the kind you buy at the store... and at about 1.00 a test why not??? most store brands measure hormones at 50 while these measure 20!! the most sensitive you can get! you can start testing way before your period is due... i belive 10dpo?? maybe even 8?? but dont quote me... if you are a pee on a stick addict these are for you!

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.

5.0 out of 5 stars Wondfos are the best value, by far. READ UPDATE about false positives! April 3, 2011

By J. Rosenberg

Size Name:25 Strips|Amazon Verified Purchase

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...."

These, you dip for 3 seconds, lay flat, and they process and clear amazingly quickly, far faster than any of the "major" brands. And you're not left with a giant stick full of pee, either (the midstream tests kind of gross me out, actually, that way.) My expected negatives (i.e. testing after my period started but before it got heavy, to be sure it wasn't implant bleeding) were crystal clear white in the test zone within about a minute. Given that I'm often testing in the rush to get my older kids off to school, saving time that way is a godsend, and I don't end up staring at a pee stick for 10 minutes trying to figure out if I can see a squint of a line. It does take a few minutes for a positive result to show up, but far less time than major store brands like Answer and First Response.

When I first wrote this, I said, "I don't expect these to be the final word: They're cheap, and there there to keep me from blowing $1 or $4 or $8 every time I want to test. If I get a positive on one of these, I'll test again to see if it gets darker, and when it's darker, I'll break out the digitals I have left over from the last round. (Because really, husbands need to see the word PREGNANT spelled out for them, it seems like...)"

Having tested at different levels of hCG for many days now, I can say that these are definitely the final word. The results are darker, stronger and faster than any other brand I've tried. They are more consistent from day to day, showing darkening as my levels of hCG go up. I got a positive digital test at 12 dpo, after these were positive late on 10 dpo, and clearly positive on 11 dpo. And at 17 dpo now, they are far darker than other brands, faster, stronger, better.

These very much satisfy the science geek in me. I used to love the Dollar Tree tests, but heck... 20 cents a test, give or take? Mind boggling.

Edited to add: I got my first visible positives with these, ahead of FRER (at least as far as taking pictures of the tests is concerned!) They are remarkably consistent from tests to test in intensity, which means that it is so easy to compare color of tests from one to the next. I can really see the test getting darker even over the course of one day, and after a chemical pregnancy where the tests never really changed, it is encouraging.

I now have about 20 of these dry and pasted to a sheet of paper in order, and I can tell you that there are ZERO evaporation lines on the negatives (3-4 dpo, too early to expect a positive.) Even the faint lines that showed up after the test time did so in a way that makes clear the progression from no color to some color to definite positives. The first hints of what I would call "evaporation" lines show up at 7 dpo on my chart, and got slowly but consistently darker from 7-10 dpo (lines showing up after the test time), before "true positives" appeared late on 10 dpo, getting darker all day 11dpo.

First Response appears to be about 1-2 days behind in intensity, and is not getting darker in the same way.

I got some "cheap" ($2 per test) strips at a drugstore, Answer strips, and they are much less clear. The test, dipped in the same sample as the Wondfo tests, are fainter, "messier" and the dye is all over the place, even the control lines are a little vague. By contrast, Wondfo strips have very well defined dye areas and the tests look much "cleaner". These are probably the least gross pee sticks I've ever seen... :) Both tests showed "positive" at the same time, but the Wondfo test are cheaper, cleaner, and much faster to give results. And days later, the Answer tests look negative, while the Wondfos are still clearly positive.

Definite will buy again, as I've nearly gotten through the 25 I've had, and after having miscarriages, I know I'll want to test often in the coming weeks, for reassurance.

I have the pink handled tests, and cannot say enough good things about them. Because they are cheap enough that I feel like I can test whenever I want without feeling guilty, I was able to get enough consistent negatives that when the strips started being slightly ambiguous, it was pretty clear something was different, even if it did take a couple days after that for the lines to get really visible. The negatives were clear, clear white. The positives are still faint, but I'm still early, and it is enough to see the progression.

Note: The pink handled tests expire in 2012. I've gotten ones that expire in 2013 from another listing, with pale pink handles that say "hcg" (much like the older blue ones) and they are also very good. Wondfo seems to change the printing and color of their handles frequently, but the rest of the test is identical, and the results are very consistent. Don't worry if your handles look different, if you are buying from this listing, or the other listing I've left reviews (and pictures) for.

I've compared the plain pink and pink hcg handles in the same sample and the results are nearly identical, and both perfectly functional. Don't worry about handle color!

UPDATE: The gals on FertilityFriend and I have been doing some experimenting. Some people may know that dipping a pregnancy test directly in cola or apple juice can create a "positive" test (not just on this brand). What we now have some evidence of is that people who drink large quantities of these beverages may have just enough of whatever chemical creates those positives in their urine to create a faint "false positive". So if you're getting questionable results with these tests, consider checking your diet. Even organic apples, freshly juiced, can turn one of these positive, which means if you eat a lot of apples or drink certain kinds of juice or soda in large quantity, they may make your results less reliable. (One man who drinks a lot of apple juice got a positive result...) If you are testing early, consider sticking to beverages which don't cause these things to turn positive on their own... So far, water, OJ and milk are all just fine. We're testing more things over the next few weeks to see what does and doesn't skew the results. Personally, I drink a ton of Vitamin Water Zero and haven't had any iffy results.

Ultimately I have to say that the false positive results with this brand are probably due to the increased sensitivity to low levels of hormone (or whatever it is in apples that causes pregnancy tests to go positive!) Read more ›

4.0 out of 5 stars Light line, but works! May 29, 2007

By ah

Size Name:25 Strips

Ok, so I bought these tests a little too late! I found out I was pregnant BEFORE they arrived. Still, just for confirmation, I used a couple. Although the line was faint, it was definitely there. They're inexpensive and work just fine!

5.0 out of 5 stars Accurate and fast results! Why spend more? May 1, 2012

By Monkey Momma

Size Name:25 Strips|Amazon Verified Purchase

I've found these tests to be extremely accurate. I just found out last night that I'm expecting baby #4! The positive line appeared immediately and my period just due.

I've used these tests in the past when I was hoping for my third baby. With my last baby, I did receive a positive line 10 days past ovulation. My high-tech digital pregnancy test was unable to detect the hormones, so these actually were more sensitive that the most expensive drugstore test. It was fun seeing a faint line progressively becoming darker with each passing day.

While in the process of trying for my third, I had a few miscarriages. Being a pee-on-the-stick addict, I would take them on a regular basis to see the line darken. These actually tipped me off that a couple of my pregnancies weren't working as I could detect the line becoming increasingly fainter as the days progressed on. As sad as I was, I appreciated knowing this as soon as possible as my clinic has their patients wait for awhile before confirming a miscarriage. I also appreciated that I could see that my levels were dropping and I didn't need to be as concerned about needing a D&C.

With my obsession of using pregnancy tests, I'm quite thankful that there is a resource to obtain these for such a low price. I would have otherwise near bankrupted myself. (Maybe not literally.) I wouldn't ever pay drugstore prices again!
