What About Early Pregnancy Tests

Home Pregnancy Test With Grains Of Salt Are Effective? ð¤ð¤ð¤

Early pregnancy test manufacturers market to your desire to get answers as early as possible. It is not hard to see the advertising on the box and read the claims of 99% accuracy along with the ability to detect pregnancy six days before your missed period.

But let us take a closer look, so you do not test too early for pregnancy. The first thing to consider is that the percentage provided on the front of the package is only accurate when you take the test on the day of your expected period and in a laboratory setting by professionals. The same goes for the the instructions printed inside the pregnancy test kit the claims of accuracy are elevated because they do not reflect real-life testing in real-life situations. The results from a University of New Mexico study reveal the chances you can anticipate getting the right answer from an early home pregnancy test:

  • One day past your expected period: 100% of pregnancies detected
  • On the day of your expected period: 96% of pregnancies detected
  • On the day before your expected period: 93% of pregnancies detected
  • Two days before your expected period: 81% of pregnancies detected
  • Three days before your expected period: 68% of pregnancies detected
  • Four days before your expected period: 42% of pregnancies detected
  • Five days before your expected period: 33% of pregnancies detected
  • Six days before your expected period: 25% of pregnancies detected

How Accurate Are Pregnancy Tests

Pregnancy tests are super accurate when you use them correctly. The pregnancy tests you get at the drugstore work 99 out of 100 times. Theyre just as accurate as a urine pregnancy test that youd get at a doctors office.

Pregnancy tests work by checking your urine for a hormone called human chorionic gonadotropin . Your body only makes this hormone if youre pregnant. HCG is released when a fertilized egg attaches to the lining of your uterus when pregnancy begins. If your pregnancy test results are positive, it means you’re pregnant. If theyre negative, it means youre not pregnant.

Pregnancy tests are most accurate when you take them after youve already missed your period.

A pregnancy test will be less accurate if its expired or if you dont use it the right way. So always check the expiration date on the package, and carefully read the directions that come with your pregnancy test.

Can You Get A False Negative Or False Positive Test

Your hCG levels are very low early in pregnancy and ramp up as your pregnancy progresses. Because of this, it’s possible to get a negative test result if you test too early. This can also happen if you don’t follow the instructions properly.

If you suspect that you’ve done the test too early, before there’s enough hCG in your urine, wait a few days and repeat the test. If it’s still negative and you haven’t gotten your period, something else may be happening in your body. “Irregular menses can and should be evaluated with blood tests to determine the cause,” says Marra Francis, M.D., a board-certified obstetrician and gynecologist. Certain medications and illnesses can cause you to skip a periodand so can excessive exercise, low body weight, early menopause, birth control pills, or stress.

False positives are very rare for women not taking fertility drugs. Nonetheless, they can happen if your pregnancy ended shortly after conception , you have ovarian tumors, you had a recent miscarriage or abortion, or your pregnancy test was expired.

How Early Can Home Pregnancy Tests Show Positive Results

In the Aerosmith song Sweet Emotion, Steven Tylers lyric the rabbit done died refers to the original way a pregnancy test was performed one that literally killed rabbits. Urine from a woman who thought she might be pregnant was injected into a rabbit, which would then be surgically opened so its ovaries could be inspected. If the woman was pregnant, the rabbits ovaries would undergo noticeable changes due to the hormone human chorionic gonadotropin that develops early in gestation. The rabbit unfortunately didnt survive.

Thankfully, pregnancy tests have evolved substantially since the 20th century. Women now have access to advanced tests that can detect a pregnancy days before a missed period. In fact, a CBS News article outlined the best home pregnancy tests according to research from Consumer Reports, based on ease of use, ease of reading results, and effectiveness. Many tests today are marketed as simple and effective, but getting accurate results comes down to when the test is taken.

How Do Home Pregnancy Tests Work Differently From A Pregnancy Test At The Doctor

The short answer to this question is that for urine tests, the home pregnancy test is not very different than the one you get at your doctor or midwife’s office. A test kit that you buy may come with more packaging and more detailed instructions, like how to collect urine, but it is essentially the same kit that you will find in any medical office.

Now, there are also blood pregnancy tests. A blood pregnancy test is also looking for the hormone hCG, though it is screening your blood. These are ordered by your doctor or midwife. It can be ordered in two varieties: quantitative or qualitative . A qualitative blood test is basically the same as a urine testit determines whether or not there is hCG. Though a blood test can usually find slightly smaller levels of hCG, so it can usually help you find out a day or two sooner.

A quantitative blood pregnancy test will actually give a number, a measurement of how much hCG is found. This number is given typically in mIU/ml . This number can be used in a number of ways. One way is that a certain number can correlate to the length of your pregnancy. This may be helpful in dating a pregnancy.

Blood pregnancy tests are generally only done for women who are having problems in their pregnancy or require special testing.1 Even if you go to your doctor’s office for a pregnancy test, the vast majority of them will offer you a urine test.
