The doctor may perform a pregnancy test on your blood or urine. Alternatively, you could buy a home pregnancy test kit, which is available from pharmacists. However, always see your doctor for confirmation of pregnancy if you use a home kit.
Your doctor can give you a blood pregnancy test as early as 11—14 days after ovulation. To perform a blood pregnancy test, the doctor draws blood from a vein in your arm. This blood is sent to a laboratory for testing. The results of most blood pregnancy tests take at least a couple of days.
The laboratory then advises the doctor of the result. Blood test results are about 99 per cent accurate and can detect lower amounts of hCG than urine pregnancy tests.
The two main types of blood pregnancy test include:. The doctor can give you a urine pregnancy test. You are asked to urinate into a plastic cup or something similar. The doctor then tests the urine using a kit that may look similar to a home pregnancy test kit. Home pregnancy test kits are available from pharmacists. However, many women who use home pregnancy test kits get inaccurate results.
The most common mistake is to test for pregnancy too soon after the missed period. Home pregnancy test kits vary in their sensitivity to hCG. Most test kits are best used about one to two weeks after your period was due. Generally speaking, most home pregnancy tests follow the same basic principles:. These tests are more sensitive than standard tests but getting accurate results that early is more difficult simply because ovulation and implantation times can vary.
If you have irregular periods, it can be even more difficult to know when might be an accurate time to try an early test. If you're having fertility treatments , be aware that this may result in a false positive pregnancy test, especially those performed early.
That's because pregnancy tests may detect the remains of fertility medications like Ovidrel, Pregnyl, or Novarel. If you expect your period on Wednesday, Thursday would be the day of your missed period.
The accuracy of a test can depend on several variables:. Are you considering taking a test before your period is late?
Consider the pros and cons before you do. Let's say you want to take an early test, despite the possible downsides.
Which test should you use? According to the research, the best early pregnancy test on the market now is the First Response Early Result, or, as it's sometimes abbreviated on fertility forums, the FRER.
This is a manual test. However, according to a FDA comparison between the two, the results show the same accuracy. This pregnancy test has clearance from the FDA to say it can detect pregnancy hormones six days before your missed period.
That is five days before your period is due. There are plenty of early pregnancy tests on the market from which to choose. Which one is right for you may depend on factors like cost, result speed, and whether you prefer digital or paper tests.
It is something to consider if you get a positive or negative result. Your doctor may order a test, or you may be thinking about ordering one yourself. Many labs now allow people to order and pay out of pocket for their blood work.
Before you do that, there are a few things you should know. First of all, there are two types of pregnancy blood tests: qualitative and quantitative. Blood tests are able to detect a smaller amount of hCG and they can detect it slightly earlier than standard at-home pregnancy tests, usually nine to 12 days after conception.
Blood test results are usually available the same day or within a day. Blood tests aren't often done to detect pregnancy because they are expensive and at-home urine tests are quite accurate and sensitive. However, people who are undergoing fertility treatments may have blood tests as part of their care. While rare, it is possible to get a negative test result on an at-home test but still be pregnant.
There are other reasons besides pregnancy that your period may be late. That said, your doctor might still order one, especially if you request it. The best time to take a pregnancy test is the day after your expected period and in the morning hours, with your first urine of the day. HCG indicates pregnancy. A pregnancy blood test also shows the amount of HCG.
If your blood tests show a very low amount of HCG, it could mean you have an ectopic pregnancy , a pregnancy that grows outside the uterus.
A developing baby can't survive an ectopic pregnancy. Without treatment, the condition can be life-threatening for a woman.

The interaction causes the testing kit to signal that hCG levels are higher than they are. In these instances, a test is unlikely to be accurate if carried out at this time. Not using the test as advised or checking the results later than the recommended time can lead to false-positive results.
