How Accurate Are Pregnancy Tests?

When you take a pregnancy test, you should look for signs of pregnancy. Some of these signs may not be so obvious, however. For example, you might not experience bloating or cramping, but you might notice your breasts are sore or your back is aching. If you think that you have these symptoms, you should consult a doctor. He or she can help you make a plan to deal with them.

Symptoms of pregnancy

Other signs of pregnancy include tender or swollen breasts and a missed period. If you’ve missed your period, chances are your pregnancy test will be positive. In early pregnancy, you might experience fatigue, mood swings, and peeing more than usual. You may also notice tender breasts, but these symptoms can be mistaken. These changes will subside as your body adjusts to the new hormones.

Types of tests

There are several different types of ovulation test. The first is a urine test, which can be done at home or at a healthcare provider’s office. The second is a blood test, which requires a small sample of blood.


The Accuracy of a pregnancy test varies depending on several factors. First, you should always repeat the test if the result is not positive or negative. For instance, a negative test can be caused by taking the test too early. Another factor is that the accuracy varies by the percentage of pregnant women in your area. The accuracy of pregnancy tests will always be less than 100%, however.

Another factor affecting the accuracy of a pregnancy test is the presence of certain medications. Many of these medications can elevate hCG levels, which can cause a false positive. This is why it’s important to wait at least 3 weeks after sex before taking a pregnancy test. Other factors that can affect pregnancy test accuracy include irregular menstrual cycles, miscalculating the ovulation date, and misinterpreting test results. Some doctors may recommend a blood test to confirm pregnancy or to rule out pregnancy complications.

False-positive results

False-positive pregnancy test results can happen for a variety of reasons. Patients who are taking certain medications and those who are suffering from chronic kidney disease are at higher risk for false-positive pregnancy test results. Other conditions such as tropho-blastic tumors and malignancy can also cause false-positive results.

A chemical pregnancy is another possible cause of false-positive pregnancy test results. In this type of pregnancy, the fertilized egg implantes outside the uterus. This causes bleeding, and it can cause a false-positive test result. This type of pregnancy can be painful and dangerous.

Before taking a test, check the expiration date. Some tests are not reliable if the date is past. Also, a pregnant woman taking some fertility medication might produce false-positive pregnancy test results. In such a case, she should check with her doctor or an obstetrician.

When to get a test

The most reliable way to check whether you’re pregnant is to get a pregnancy test. There are several different types of tests available, and some of them are much more sensitive than others. Generally, it’s best to get a pregnancy test at least 3 to 6 days before your period is due. The test is less accurate if you take it too early, and it can result in a false negative.


A pregnancy test can tell you whether or not you are pregnant by showing a line, color, or symbol. The digital variety shows the words “pregnant” or “not pregnant.” If the test shows that you’re pregnant, the next step is to schedule an ultrasound to confirm your results.
