Best Pregnancy Test/Most Sensitive Pregnancy Test

Are you suspecting pregnancy and don’t know which kit to use for accurate results? There is a variety of pregnancy tests in the market today. Even though, how do you determine the best? 

Understanding how over the counter pregnancy tests work, will give you an insight on which test kit to buy.

How do pregnancy tests work?

Home pregnancy test is engineered to test or detect the presence of a pregnancy hormone called Human Chorionic Gonadotropin (hCG) in your urine. This hormone is first released into the bloodstream and later on secreted into urine.

The home pregnancy tests are not able to detect the hCG hormone as soon as it is secreted. Even though some pregnancy tests may claim to give accurate early pregnancy results, you may have a reason to dismiss that, when you understand how to pregnancy tests work.

False-positive results are common with early pregnancy tests. For actual results, you should consider waiting until you have missed your period or noted some early pregnancy signs.

Where can I buy a pregnancy test?

Pregnancy tests are sold over the counter meaning that you do not need a prescription from your doctor for purchase. They are also available on online platforms.

How soon can you take a pregnancy test?

How early should I test for pregnancy? A much early pregnancy test is unlikely to be accurate. If you want accurate test at home, timing is the key.

A fertilized egg takes 6-10 days to implant itself in the uterus after ovulation.

  • The best pregnancy test detects pregnancy hormone 9 days post ovulation, 5 days before your period.

Are all the tests the same?

Pregnancy tests do not work the same. Some can detect hCG in small concentrations than others. This means that you can know that you are pregnant, with the slightest hCG in your body.

Pregnancy tests report hCG concentration in milli-international units (mIU) per milliliter. For example, a pregnancy testing brands with 30mIU/ml can detect pregnancy earlier that of 40 mIU/ml.

Additionally, depending on the brands you choose, you may note blue or red lines on the strip. Some reveal a plus (+) or a minus (-) sign, while the rest change the color of urine sample into the indicated color.

Digital pregnancy tests can show the words `pregnant’ and `not pregnant,’ also some of these can show how long ago you conceived. However, it is important to note that the digital pregnancy test could be more expensive than the manual ones.

  • Whether you choose a manual or digital testing kit, you should be able to get accurate results.

How is pregnancy test sensitivity determined?

The body starts producing the hormone hCG in small amounts after implantation has taken place. The most sensitive tests should test at least 5mIU before showing positive results.

Those that can pick the least amount of pregnancy hormone are said to be more sensitive than the rest. For example, one that can pick 6Miu/ml is more sensitive compared to one that can pick 25MmIU/ml.

This is to say that the lower this unit of measurement is, the more sensitive the pregnancy test is.

How do I know which pregnancy test to buy?

Most pregnancy testing kits in the market have a sensitivity of about 25mIU/ml, meaning that are more accurate 10-15 days after implantation has occurred. This is a day or two after your missed period.

However, for those women who cannot wait until a missed period to take a pregnancy test, there are early pregnancy tests that are sensitive and equally accurate.
