Is the pregnancy test accurate? | NHS

A pregnancy blood test at your doctors office is another way to confirm a pregnancy.

The blood test can detect the pregnancy earlier than an at-home urine test eight days after ovulation is the earliest a blood test could detect a pregnancy, says Dr. Merhi.

Should you receive a positive at-home pregnancy test result, your doctor will often perform an in-office blood test to confirm the presence of HCG. This and additional blood tests also provide additional information about your health and the health of your pregnancy.

Blood tests are also needed to check for complications of pregnancyfor instance, if you are at risk for ectopic pregnancy , miscarriage or an abnormally progressing pregnancy, says Dr. Culwell. because they can measure whether your pregnancy hormone levels are progressing normally or decreasing.

Should you experience a miscarriage, HCG can remain in your body for a few weeks, and additional tests taken in the weeks following can lead to a false-positive result, says Dr. Merhi.

Is It Possible To Get A False Negative Pregnancy Test Result

Yes. The most common cause of a false negative result is performing the test too soon after conception, when hCG levels are too low to be detected. If your ovulation happens later than usual, this means that the first day of a missed period can be too early to get an accurate result .

Waiting a week or two after a missed period before performing a urine pregnancy test will minimize the chance of getting a false negative.

Rarely, false negative results can be caused by very high hCG levels associated with pregnancy-related tumors.

When Is The Best Time To Take A Pregnancy Test

You can take a pregnancy test any time of the day. But if theres a chance youre early in pregnancy, take it in the morning when your urine is most concentrated so the test can more easily detect the HCG hormone, says Dr. Culwell.

The best time in the cycle to take a test would be after you have missed a period, says Dr. Culwell. This will make it less likely that you might miss an early pregnancy if the HCG levels are too low to be picked up by the test.

You Were Pregnant: Early Pregnancy Loss

A faint positive line can also be a sign of a very early miscarriage, sometimes called a chemical pregnancy, which occurs within the first 12 weeks of a pregnancy, often much earlier.

If you take a home pregnancy test after a miscarriage, your test may reveal a faint positive line. This is because your body may have residual pregnancy hormone in its system, although youre no longer expecting.

You may experience bleeding that resembles your menstrual cycle and light cramping. Bleeding can occur around the time when you expect your next period, so you may never know of the early miscarriage.

But if you take a home pregnancy test while bleeding and the results show a faint positive line, you may have had a pregnancy loss.

Theres no specific treatment, but you can talk with your doctor if you suspect a miscarriage.

Early pregnancy losses are not uncommon and occur in about 50 to 75 percent of all miscarriages. These miscarriages are often due to abnormalities in a fertilized egg.

The good news is that women who have had a very early pregnancy loss dont necessarily have problems conceiving at a later time. Many women eventually have healthy babies.

What you can also do is take blood pregnancy tests, especially if you have been getting a lot of negatives on your home pregnancy tests but have reason to believe that you are pregnant.

Again, a good time to take a test would be several days late.

Blood pregnancy tests can also be a good option to consider for women who have experienced miscarriage, pregnancy complications or health risks in the past. This way, the most crucial first weeks of your pregnancy will be closely observed.

Sperm exposure poses the highest risk of pregnancy from around the middle of the cycle to about 2 weeks before your anticipated period, because this is when most people ovulate. This is only true in general, and it might not be reflective of any given cycle, so you shouldnât rely on this rough estimate for pregnancy prevention.

Sperm exposure towards the beginning or the end of the cycle in general poses less risk of pregnancy, because itâs less likely that a person ovulated close to or during those times.

You should take a pregnancy test or contact your healthcare provider if your period is more than 9 days late.

To avoid a false negative, itâs best to wait a few days after your expected period. Itâs up to you if you want to take it sooner.

What Happens If You Take A Pregnancy Test Too Early

Remember that hCG levels increase rapidly after implantation, which is when a fertilized egg attaches to the uterine lining. Completed implantation is a slow process that can take up to two weeks.

You can buy a pregnancy test at your local pharmacy, drugstore, grocery store, and some convenience or dollar stores. Pregnancy tests are usually inexpensive they can cost as little as a dollar. Sometimes you can get a free pregnancy test at certain health centers.

You can also get a pregnancy test from your nurse or doctor, community clinic, or local Planned Parenthood Health Center.

Crisis Pregnancy Centers give free pregnancy tests and claim to offer information and help. But theyre run by people who may not be medical professionals, and dont believe in giving you honest facts about pregnancy and all of your options.

The Best Time Of Day To Take A Pregnancy Test

How soon can I take a pregnancy test?

The time of day you take a pregnancy test does matter to a certain extent. Youre more likely to get an accurate result if you take the test in the morning. This is especially true if your period is not yet late, or if your period is only a couple days late.

At-home pregnancy tests work by detecting the hormone human chorionic gonadotropin in your urine. Unless you get up in the night to pee often , your urine is more concentrated when you first wake up. This usually means that the amount of hCG is a bit higher, and youre more likely to get a positive result if youre pregnant.

However, you can still take a pregnancy test in the middle of the day, or even at night. Youre just more likely to get a false negative, especially if your period isnt that late, and especially if youve been drinking a lot of water and your urine is diluted.

Can Any Medication Or Medical Conditions Affect The Result

Testing too soon after using fertility drugs that contain hCG can give misleading results. If you have recently stopped taking hormonal contraception or are using fertility treatments such as clomiphene citrate, your periods may be irregular leading you to test too early.

If you have recently been pregnant you may get a false pregnant result. Ectopic pregnancy, ovarian cysts, menopause and some very rare medical conditions may give misleading results.

If you have a pregnant result it is possible that you later find that you are not pregnant due to loss of the pregnancy in the early stages. Some women who are more than 6 weeks pregnant may get misleading results due to high hCG levels .

If you get unexpected results you should talk about them with your doctor.

The most surefire way to confirm a pregnancy is through a blood test or ultrasound done at a doctors office. But before visiting the clinic, at-home pregnancy tests can give you answers with about 99% accuracy .

How exactly do these tiny sticks detect a pregnancy? It has everything to do with the level of hCG in your urine.

Here’s what you need to know about hCG:

  • When a fertilized egg implants into the uterine lining, the body starts ramping up production of hCG increasing by roughly 50% every day during the early stages of pregnancy in order to nourish the developing embryo.
  • Urine-based pregnancy tests compare the levels of hCG in your urine to a predetermined hCG threshold that indicates pregnancy.
  • For a positive result, urine generally needs to have about 20 mIU/mL of hCG. Urine that contains anything less than 5 mIU/mL of hCG will show as negative.

You might be wondering if you should also have a blood test to check if you are pregnant. 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, there are two types of pregnancy blood tests: qualitative and quantitative.

  • Qualitative tests measure whether hCG is present in your blood or urine. They pretty much give a yes or no answer as to whether youre pregnant. Or, more accurately, whether you have enough pregnancy hormone to get a positive result. Home pregnancy tests are qualitative.
  • Quantitative pregnancy tests measure the amount of pregnancy hormone in your blood. This is sometimes called a beta hCG test. These are usually done to see how a pregnancy is progressing. For example, your doctor may order two beta hCG tests a few days apart to see whether the level of hCG is increasing as expected or not. This might be important if you had trouble conceiving, have a history of early miscarriage, or an ectopic pregnancy is suspected.

Pregnancy Test How Long To Wait

A pregnancy test measures the amount of a hormone called human chorionic gonadotropin in your urine. hCG is produced when a fertilized egg attaches to the wall of the uterus. The amount of hCG in your urine doubles every two to three days in early pregnancy. Most pregnancy tests can detect hCG levels as low as 25 mIU/ml.

To ensure the accuracy of your pregnancy test, you should wait until at least the first day of your missed period to take the test. If you test too early, you may get a false negative result because not enough of the hCG hormone has been produced yet. If you test too late, you may get a false positive result because the hCG level may start to decline after the eighth week of pregnancy.
