The correct pregnancy test is not the concern of many women when trying to get home pregnancy test. This is a measure that is used quite widely and commonly, so are there any reasons that might affect the results?

What is a pregnancy test?

The pregnancy test works on the principle of detecting the concentration of hCG (Human Chorionic Gonadotropin) present in the urine sample. HCG levels are released only and increase gradually when an egg is fertilized and attached to the lining of your uterus - the beginning of pregnancy. Therefore, the hormone HCG is also known as the pregnancy hormone.

Therefore, the pregnancy test or blood test is based on detection of this concentration to determine whether you are pregnant or not.

When the hCG level is 25 mIU / ml or higher, the pregnancy test will be positive, meaning you are pregnant. If negative, not pregnant, the hCG level is less than 5 mIU / ml.

With the activity based on hCG concentration development, are pregnancy test results accurate? And should women have absolute confidence in this result? Let's find out in the next section.

The time of pregnancy test is too early or too late

Usually, hCG levels can appear in the blood and urine about 10 to 14 days after sexual intercourse and conception  is successful. These concentrations are usually highest by 8 to 11 weeks of age.

Therefore, if you take a pregnancy test earlier than this time, the hCG level is still low now, so the pregnancy test will not detect it, leading to inaccurate results.

If the pregnancy test is quite late, the amount of HCG in urine that is too large is likely to inhibit the test and reverse the results.
