How Soon Can I Take A Pregnancy Test
There are a number of early pregnancy tests that claim to give you a result up to 6 days before the day of your missed period . However the earlier you use them, the less reliable they are and the higher the risk of a false negative or false positive. Some of them have just over 50% accuracy when used super early the same as flipping a coin.
We agree with the advice from doctors, midwives and fertility experts to wait until the day after your period is due or at least until the test youre using has 99% accuracy. Though we do understand that it can be tough to hold out that long.

A positive result can bring on a surge of excitement it can also come with its fair share of anxiety. If you want to take a second test for reassurance, go for it just dont feel compelled to buy out the pharmacys entire stock. If one test is positive, the rest will be too, says Pope. Its time to schedule a prenatal appointment with your doctor and follow up for next steps.

If you think you are pregnant, you may want to test yourself at home with a home pregnancy test. You can buy test kits at a drug store without a prescription. Home use kits measure a hormone called human chorionic gonadotropin in your urine. However, these tests are qualitative, and the results are either positive or negative for pregnancy.
The most sensitive test of pregnancy is best performed by a laboratory using a sample of your blood. These tests not only detect human chorionic gonadotropin but also can indicate the amount of the hormone, which doubles every 2-3 days during the first several weeks of pregnancy. These more sensitive tests can tell you approximately how long you have been pregnant and even detect specific problems with the pregnancy. Your doctor can perform this test.
Initially, many women prefer the privacy, convenience, and quick results from home test kits. Home pregnancy tests are not as accurate as blood tests done by your doctor. They also cannot determine if your pregnancy is developing as expected. The hormone hCG may be detected in urine about 2 weeks after conception . With the home test kit, you place a drop of your urine on a prepared chemical strip. It usually takes 1 or 2 minutes for the strip to indicate the result.

Similar to the One Step tests, these are simple test strips without the plastic wand to hold when testing, so its advised you collect a wee sample in a pot first, then dip the test strip in there for 10 seconds. The test takes up to 5 minutes to show a result, so if patience isnt your strong point, this might not be the one for you check out the First Response Rapid Results test instead.
The test strips are able to detect hCG levels of 20mIU, but Firstvue recommends waiting until the first day after your missed period to test for a reliable result of 99% accuracy.

What Should I Do With The Results Of A Pregnancy Test
If you have a positive pregnancy test, you will want to schedule an appointment with the doctor or midwife of your choice. They will guide you further in how to care for your pregnancy. They will also be the person with whom you can share concerns or ask questions, even prior to your appointment.
Many women are surprised at how long it seems to take to get in to see a doctor or midwife in early pregnancy. This is not uncommon. It can be normal to not be seen until after you would normally be eight weeks pregnant or have missed a second period. If this concerns you, speak up. Perhaps you have a medical concern that needs to be addressed sooner. Don’t hesitate to ask for something different. If you aren’t being heard, consider looking elsewhere for your care. Most offices offer, at the very least, a nurse call line.
If your pregnancy test was negative, you will want to wait and repeat it. Most pregnancy test kit instructions recommend waiting at least a week to repeat the test. If the test is still negative, you will want to schedule an appointment for a physical exam. There may be any number of reasons why your pregnancy test is negative and you haven’t started your period.

Whats Inside A Pregnancy Test
Both digital and analog pregnancy tests use the same test strip to measure the pregnancy hormone, hCG , in your urine. If hCG is present at a significant level, then the test will be positive. For regular analog tests, this means two lines will show up in the test window.
In digital pregnancy tests, a small computer is built in that reads the strip and displays the results on a small LCD screen. Thats rightinside your digital pregnancy test is an analog pregnancy test! When buying a digital home pregnancy test, you arent paying for a better test. You’re paying for the battery and electronics required for the pregnancy test to read the lines for you .

How Home Pregnancy Tests Work
Home pregnancy tests measure the small amount of hormones that the body produces when a fertilized egg is implanting and beginning to grow. Specifically, they contain antibodies that can pick up the presence of human chorionic gonadotropin in pee.
Two types of hCG are important in early pregnancy. The first, hCG, is a hormone responsible for forming the mechanism by which the placenta gives nutrients to the fetus. The second, hyperglycosylated hCG , is a whole different, unrelated molecule.
The two hCGs differ in when theyre present in pee during early pregnancy. In very early pregnancy only hCG-h is present, Cole said.1
Regular hCG is not produced until youre about four to five weeks pregnant. Amounts of this hormone double roughly every 72 hours in early pregnancy, reaching their peak around eight to 11 weeks, then level off for the remainder of the pregnancy. Levels of hCG in pee can vary a lot as well. If youre pregnant and its been three weeks since the start of your last period, you can have anywhere from 5 to 50 mIU/mL in your pee. At six weeks past your last menstrual period, this spread is from 1,080 to 56,500 mIU/mL. According to studies and other researchers, hCG is present at low levels in the body even when a person is not pregnant, so the tests cant be too sensitive or they might erroneously register a false positive.
False negatives, where you are pregnant but get a negative reading on a pregnancy test, are much more common than false positives.

What The Pros Said
The consensus from healthcare professionals across the board was that it doesnt really matter what home pregnancy test you use they all work more or less the same way, it just depends on your preferences.
If thats the case, what does matter when taking a home pregnancy test? They had a few key suggestions:
- Make sure the test isnt expired.
- Wait until after youve missed your period to test .
- Follow the instructions on the box exactly.
Additionally, there are some key differences that can make one test a better choice for you than another. Weve selected our top home pregnancy test options based on sensitivity, convenience, speed, and cost to help you pick the best pregnancy test for you.
Surprising Details About The Most Sensitive Urine Pregnancy Tests
Heres a multiple-choice question to consider:
Which type of qualitative urine hCG test devices are capable of detecting the lowest concentrations of hCG?
A. The devices that can be purchased at a local pharmacy for use at home tests).
B. The devices used in hospitals, clinics, and doctors offices tests).
C. Both types of devices are equivalent.
The correct answer is A.
Surprised? I was too. Logic suggests that the urine hCG tests that are frequently used in healthcare settings would probably do best at detecting the hormone at lower concentrations.
There have been two studies that have investigated the analytical sensitivities of urine hCG tests. One study used samples prepared by adding hCG to male urine to achieve hCG concentrations of 6.3, 13, 25, and 50 IU/L. Fifteen different OTC pregnancy tests were evaluated, twelve of which claimed an hCG detection limit of 50-100 IU/L . All but one of the fifteen devices produced positive results at an hCG concentration of 25 IU/L. Curiously, the one device that did not claimed a detection limit of 25 IU/L.
We suspect that home pregnancy tests have greater analytical sensitivity than their POC counterparts because of differences in the amount of urine the devices require. OTC devices absorb urine from the urine stream during voiding and, as such, they use a much larger volume of urine than the tests used in healthcare settings .

Are Analog Pregnancy Tests As Accurate As Digital Pregnancy Tests
Yes. Most analog tests are as accurate as digital tests, including the Natalist Pregnancy Test which is 99%+ accurate in predicting pregnancy at three days before your expected period.
To test early, youll want to look at the sensitivity of the test. A pregnancy tests sensitivity is based on what levels of hCG it can detect, so a highly sensitive test will be able to detect lower amounts of hCG, meaning you can test several days before your missed period.
Early in pregnancy, hCG levels rise rapidly, doubling every two days. The closer you are to your missed period, the more reliable your early pregnancy test results will be.
Dollar Store Pregnancy Tests Do They Really Work
When looking for the best pregnancy testing kit to buy, you will come across $1 pregnancy tests. So, you may be wondering, do dollar store pregnancy tests work just as well as their more expensive counterparts?
All home pregnancy testing kits expensive ones and $1 pregnancy tests work on the same principle: they need to be sensitive enough to detect levels of hCG. Dollar store pregnancy tests can accurately detect if you are pregnant, but usually, the sensitivity of Dollar Tree pregnancy tests or other hCG testing kits that cost $1 is not as high as the brand leaders.
However, you will find that most testing strips that cost $1 are sensitive at 20 mIU/mL or 25 mIU/mL. According to research already mentioned in this article, 25 mIU/mL hCG should be enough to accurately detect pregnancy a day after your missed period.
The difference with the sensitivity of Dollar Store pregnancy testing kits is that you have to wait until the first day of your missed period to get an accurate result. However, because of the cheap pregnancy test price, you can afford to buy a few strips and test every second day.

How Many Pregnancy Tests Should I Take
Unless you made a mistake and didnt follow the test instructions correctly, dont take multiple tests on the same day, or the next. The results will be the same.
If your pregnancy test is positive, there is little value in taking additional tests in the hope they will be negative. Instead, make an appointment with a medical practitioner and discuss what happens next.
If your result is negative, wait a week before taking another test. This is especially true if you take the first test before the day your period is due. At this stage, theres still a good chance these tests will provide a false negative.
If you cant wait that long and Ive been there do wait at the very least two days, preferably four. On average your hCG levels double every two days, so even waiting one day is unlikely to change the result.
If you continue to get negative results and you are still late, visit a doctor as there are many other medical reasons why your period can be late.

What Are The Criteria For The Most Sensitive Pregnancy Test
The most sensitive pregnancy test is the one that can detect lowest levels of hCG. A pregnancy test for early pregnancy detection is the most sensitive pregnancy test.
The most sensitive pregnancy test can detect traces of hCG present in urine. Unlike a sensitive pregnancy test, others require the hCG levels to rise high for detection by them.
The Best Pregnancy Tests
“Is it possible that I’m pregnant?” can be one of the most nerve-wracking questions for a woman to deal with. But with so many pregnancy tests and ovulation kits on the market today, how can you tell which is relaiable?
Consumer Reports senior editor Nancy Metcalf talks about the best pregnancy tests and ovulation kits available. Get the recommendations on Tuesday’s The Early Show.
Method:All home pregnancy test kits use monoclonal antibodies to detect a hormone known as human chorionic gonadotropin , which is produced by the developing placenta beginning on the day on which the embryo implants in the uterine wall. Concentrations of this pregnancy hormone vary widely from woman to woman, but the more sensitive tests can measure lower levels of hCG.
All 18 brands tested by “Consumer Reports” employ similar technology – most use sticks with absorbent wicks that are held directly in the urine stream, and most allow women to collect urine in a cup and then dip the stick. Regardless of collection method, reading the results is the same for every kit: if a line appears in the window after a specified number of minutes, the test is positive.
Working with an independent laboratory that specializes in hCG studies, CR spiked hCG-free urine with varying concentrations of the hormone “to mimic the range found in normal early pregnancies.”
They tested each product at increasing levels of hCG concentration until a positive result was attained.

When Should I Take A Pregnancy Test
If youve been trying to conceive, youre probably anxious to take a testand stat. But youll want to plan your fateful potty-trip wisely. The truth is: Home pregnancy tests are most accurate when you take them after you have already missed your period, explains , MD, reproductive endocrinologist and medical director of HRC Fertility in Orange County, California.
Early-result pregnancy tests are designed to detect the hormone as early as six days before your missed period. Still, the odds of getting a false reading narrows as you approach the date of your expected period. You should also try to take your home pregnancy test when you wake up, as first morning urine is most concentrated, meaning a test is more likely to detect hCG levels, explains Pope.
