Currently the most accurate non invasive test for detecting a risk of Downs syndrome during pregnancy is the measurement of the nuchal translucency with an ultrasound between 11 to 14 weeks of pregnancy. I combined a few recipes I found online. How many dates during pregnancy should I eat each day?

And I mean VERY minimal! She is my first and I would say there is certainly a concern for having a labor that went too quickly. Epub 2015 Mar 19.

However, we do think you should verify your results with our top pick, the. Show less The answer that a pregnancy test gives is a life-changing one, so you need an accurate, clear result. In our research, manual tests handily beat the digital tests in terms of how fast they could provide an accurate reading. Digital tests were prone to erroneous readings. After taking a few apart, we also learned that the digital tests actually use the exact same strips you find in manual tests, only the digital test has a sensor to detect the darkened line for you—often about a minute after you would be able to eyeball it yourself. This is a strip test—literally just a thin strip that you dip in a cup of your pee. But out of the strip type tests we tried, ClinicalGuard was by far the cheapest. It costs about half as much as the other strip tests, and less than a tenth of the cost of a single manual test. I also have 10-plus years of lab experience, so I can accurately make solutions and test them although I am not really used to doing it with my own pee. That also means that I was able to give a practically endless supply of positive pregnancy pee for testing. Additionally, I interviewed , an ob-gyn at in Los Angeles. How to count pregnancy in weeks A quick interjection about pregnancy terminology—ever heard someone say that they are x weeks pregnant? Because ovulation happens roughly two weeks after this date, you basically get two weeks worth of pregnancy free, as far as the terminology goes. I will use this terminology for the whole of this guide. To learn why some tests can give earlier results than others, read. How we picked Pregnancy tests should be four things: sensitive enough to pick up on pregnancy early on, easy to use, easy to read, and relatively cheap. Is this combo too much to ask for? There are a number of best pregnancy test lists out there. However, the ones from and are not very rigorous. The reviews from Preconception Weekly now defunct and both list inaccurate numbers for how sensitive certain tests are and that last one seems to only be trying to sell its own tests. Consumer Reports looked at pregnancy tests in 2003, although the results are not online anymore , and the tests have changed slightly since then. So a new guide was definitely needed. We lucked out in terms of testing, because there is a wealth of scientific data on the accuracy of home pregnancy tests. That being the case, we did not run our own accuracy tests, but instead relied on the experts. And the most expert-y of experts we could find was biochemist Laurence Cole, who runs the. First Response digital and manual tests are the most sensitive, and can detect hCG-h, the kind of hCG that women produce only very early on in pregnancy, to determine pregnancy sooner. Clearblue Easy and EPT are both less sensitive than First Response, but more sensitive than other tests on the market. They also detect the early kind of hCG, but not as well as First Response. So we decided to test these tests for usability and readability. In other words, we peed on these to determine which ones were the best to use. The digital tests tend to be a bit more expensive than the manual versions. On further evaluation, the First Response manual and digital tests both detected 97% of 120 pregnancies on the day of missed menstrual bleeding. The EPT manual and digital devices detected 54% and 67% of pregnancies, respectively, and the Clearblue manual and digital devices detected 64% and 54% of pregnancies, respectively. However, readers have been asking us about cheap, strip-type tests you can buy online. For more information, check out our assessment of. How we tested All the pregnancy tests I took for the first round of testing. Photo: Leigh Krietsch Boerner I took six of each of our contenders and put them through the paces. I tested them multiple times using both the midstream and pee-in-a-cup-and-dip methods. I pried the digital ones apart to see what was going on behind the curtain. Since I was nine months pregnant at the time of testing, I dipped them in water and, in one case, had my husband pee on one to get negatives. I diluted my own urine down by 1,000 times in water to see what a barely positive looked like. I held them upside down while waiting for the results a big no-no, according to the packaging , just to see what happened. In short: I totally abused these things. Two of our female editors, both not pregnant at the time of testing, also tested each of these in both the midstream and dip methods, and added their feedback. I also tested the strip tests while not pregnant, and compared how easy they were to dip and read. None of these tests gave what are known as , which are lines that your pee sometimes makes on manual tests that can be mistaken for a positive pregnancy line. Results came in quickly, taking only 40 to 45 seconds. What the manual tests looked like with a positive result. Not much chance of a mistake there. However, my hCG levels when I took these were much higher than in early pregnancy, so it would have been a red flag if they had been hard to read. Note that this includes the older model of the First Response test. The three manual tests after dipping in the second dilution of positive pregnancy pee. It was really hard to get a picture of this, but you can see the the bottom test, the First Response manual again, this is the old version , was clearly positive. For the EPT and Clearblue Easy, it was difficult to determine if they were giving a negative or a positive. Photo: Leigh Krietsch Boerner To mimic the earliest days of pregnancy, I prepared a very dilute solution of positive urine. As you can see in the photo, the First Response manual test showed a very clear positive response with a strong fuchsia line, while the other pregnancy tests barely registered. The old First Response manual test top next to the new, redesigned test bottom. Note larger tip and curved handle on the new one. Nothing about the hCG-measuring materials has changed, but the tip and stick were given a new ergonomic, user-friendly shape. It has a nice wide tip, so hitting that target over the toilet is a little bit easier. It also has a curved handle with grippy texture on the back that makes it easy to both hold onto and pick up from a table. Plus the handle is big enough to wrap your whole hand around, not just pinch between thumb and forefinger. That made me feel that I was less likely to drop the whole dang thing in the toilet bowl. The First Response test is easy to read in my opinion, although the varying darkness of the two lines can be a little confusing. In one test, with full-strength, positive urine, the line on the right was much, much lighter than the positive line. It does say in the brochure that this can happen. This changed when I tested the diluted solutions of urine. In this case, the line on the right was much brighter than the positive line. However, there was no mistaking the positive line. Some people have complained that the curved window in the redesigned test makes it harder to read. And, yes, depending on how the light hits that plastic window, there can be a reflection that some people might mistake for a second line. But considering that this goes away if you pick the test up and move it slightly, this is a pretty minor flaw. While it was not as sensitive as the First Response manual test, the did come in second due to its simple design. It has a thin, grip-friendly handle, making it better to hold than the EPT test. Like the First Response test, it has a fat tip, making it a generous target for a stream of pee. The absorbent pad on the Clearblue Easy manual test also turns pink when it gets wet, so you can see when it starts working. I got a positive from the Clearblue Plus test in as little as 10 seconds on one occasion, but the average was more like 45 to 50 seconds, for either positive or negative. The Clearblue digital tests took anywhere from 1. For both of the Clearblue tests, the box says it takes 3 minutes for the result. Of the three strip tests we looked at, ClinicalGuard was the cheapest. Everything else—the size, the time to result, ease of use—was Exactly. But the ClinicalGuard strips were about half the cost of the other two strip tests we assessed: Wondfo and Easy Home. But if the price changes in the future, just go for the cheapest test. For more information, see below. I was pretty surprised by this; the two times I took pregnancy tests, I made a beeline for the digital tests. I did not want any ambiguity about a positive or a negative test. I wanted the thing to tell me a clear yes or no. But I found that the manual tests did give a clear yes or no. Also, the manual tests are much less likely to go poof on you. I did have a couple of problems with the digital tests, but none with the manual tests. They are also much faster at giving a result: 40 seconds versus 3 minutes? In the grand scheme of things, 3 minutes is not long to wait at all. Digital tests are really just manual tests with a battery and a sensor that reads the lines for you. The funny thing is that digital tests are really just manual tests with a battery and a sensor that reads the lines for you. I cracked open all three brands of digital tests, and they look just like the manual ones on the inside. The strip inside a cracked-open Clearblue Easy digital test. Photo: Leigh Krietsch See that strip in there? But it takes longer to do this than you would. Digital tests also tend to be less sensitive than manual tests. According to the boxes of all these tests, these are the stats: First Response: The manual test picks up on 76 percent of pregnancies five days out, while the digital test says yes to only 60 percent of women who are actually pregnant. Clearblue Easy: The manual tests give a positive to 56 percent of women who are actually pregnant four days before a missed period, and the digital gives a positive to 51 percent of pregnant women. These numbers are 98 percent and 95 percent respectively, for the day of a missed period. EPT says that its manual tests give a pregnant result to pregnant women 53 percent of the time four days before a missed period, and the digital test 53 percent of the time. On the day of a missed period, these numbers jump to 99 percent. But to get even more sensitive within each brand, go for the manual version. A word about strip tests Strip tests are super, super pared-down pregnancy tests. The strip tests cost less than a tenth of this price. The accuracy information we used for manual and digital tests came from a paper written by Larry Cole at the. So the strip tests may not work for you early in your pregnancy. The strip pregnancy tests that we tried. From left: Wondfo, Easy Home, and ClinicalGuard. We also think the strips should be a supplement to the top pick. If you do get a positive, verify that result with either our top pick or the runner-up. The competition gave me some problems, mainly a false negative. I also had technical problems with a second, which eventually gave me a positive, but only after waiting for 6. For reference, the other tests gave results in 3 to 3. The box says it should take 3 minutes. The is a bit clunkier and heavier than the manual test. Both were really easy to read, but the manual test gave faster results. The manual tests took a speedy 20 to 30 seconds, although it usually took up to 40 seconds for the test line to appear. EPT suggests not reading the test before 2 minutes. The was the speediest of the lot and gave me results in less than 2 minutes. The digital tests are supposed to be read after 3 minutes, although the brochure says some results show up in as little as 1 minute. The first digital EPT test I took was a dud, although I did nothing wrong. The and strip tests are pretty much identical. The strips look exactly the same, and the included directions are exactly the same, except that the Easy Home directions have their logo at the top, and some parts are slightly larger than the Wondfo directions. How pregnancy tests work Getting pregnant is not as easy as your eighth-grade health teacher led you to believe. Besides having to have sex at the right time of the month, the egg has to get where the sperm can access it, the sperm has to randomly hit the egg within the 12- to 24-hour fertilization window, it has to get inside, then this fertilized egg has to travel back up to implant itself in the uterus. Getting pregnant is hard. What pregnancy tests do is measure the small amount of hormones that your body produces when the fertilized egg is implanting and beginning to grow. Specifically, they contain antibodies that can pick up the presence of human chorionic gonadotropin hCG in your pee. According to Cole, there are two types of hCG that are important in early pregnancy. The first, hCG, is a hormone responsible for forming the mechanism where the placenta gives nutrients to the fetus. The second, called hyperglycosylated hCG or hCG-h , is a whole different, unrelated molecule. In very early pregnancy, weeks three and four, only hCG-h is present, Cole said. This makes sense, as this is the molecule that drives implantation of the egg. Levels of hCG in pee can vary a lot as well. According to studies and others, premenopausal women have low levels of hCG present in their bodies at all times. This amount peaks at about 1. Fortunately, pregnancy tests currently available over the counter are nowhere near this sensitive. Women who are menopausal do have a higher amount of hCG in their bodies, and in some circumstances might get a positive reading on a pregnancy test. Another way you might get a false positive is if you have a chemical pregnancy, which is relatively rare. Eventually, hCG levels will return back to normal. False negatives, where you are pregnant but get a negative reading on a pregnancy test, are much more common. False negatives, where you are pregnant but get a negative reading on a pregnancy test, are much more common. The most accurate time to take a test is after you miss your period, and the longer you wait after you miss your period, the more accurate the test becomes. How to take a pregnancy test First of all, read the dang directions. While they do tend to be similar, not all of them are the same. There are two ways to take a test: Either urinate on the absorbent strip for around 5 seconds the midstream method , or pee in a cup and dip the absorbent strip in there, from anywhere from 5 to 20 seconds. For our testing, we used both methods. And personally, I recommend the pee in the cup and dip method for a couple of reasons. This did not happen to me, but I had a couple of close calls. The pee-and-dip method does require that you find a clean cup first. But it is nice in that if you screw up a test, or it goes flop on you, you can try another test right away most tests come with two or three in a box. It also works well if you want to test with first-thing-in-the-morning pee. This method also gives you a bit more control, and again you can retest right away if you wish. The directions for the models we tested all said about the same thing: Keep the tip pointing downward, then lay the whole thing flat while you wait for the tests to develop. This takes anywhere from 30 seconds to 3. The manual ones are faster, the digital slower. For the manual tests we tested, the directions all said not to read the result after 10 minutes. But looking at the ones I did, they still had the same result days after testing. For the digital tests, all of the First Response ones were dead after two days, as were the negative Clearblue tests. For some reason, if you have a positive Clearblue test, it holds its battery life for up to six months? I guess this is in case someone wants to keep the test to show people? Whatever floats your boat. This dilutes the hCG in your urine and makes a false negative more likely. This dilutes the hCG in your urine and makes a false negative more likely. I then took 5 mL of this solution and added it to 95 mL of water for dilution 2. Unfortunately, I did not know the hCG concentration of my pee at this point. And so it is. So that would be about 0.

The Custodes Indicator is 93% accurate in detecting when you conceived. The First Response test is easy to read in my opinion, although the varying darkness of the two lines can be a little confusing. Sometimes a pregnancy test is able to find pregnancy hormones in your urine as early as 10 too after unprotected sex. The lower the sensitivity, the earlier a pregnancy test dating pregnancy test positive.
