hCG levels in the blood

Pregnancy tests detect a hormone called human chorionic gonadotropin or hCG. hCG begins to show up in the urine ten days from the day the woman conceives.

"How soon can I take a pregnancy test?"

If you've ever had that thought after having unprotected sexual intercourse, you know how important it is to understand how hCG levels rise during pregnancy.

Pregnancy tests detect a hormone called human chorionic gonadotropin or hCG. The hormone is only present in pregnant women. The hCG can be detected in the blood or urine.

A lot of changes take place in a woman's body when she becomes pregnant. One of the quickest changes in the production of hCG. The hormone begins to show up in the urine ten days from the day the woman conceives. At-home pregnancy tests check for the presence of hCG in urine. If you use this test correctly, it can be accurate.

Urine tests don't indicate how much hCG is present in your body. They only determine pregnancy if hCG levels are high enough to support a chemical reaction that can confirm fertilization. The test doesn't measure "how much" it measures "enough."

The hCG levels in a pregnant woman's body are highest at the end of the first trimester. The hCG levels decrease after that. In the first three weeks of pregnancy, a pregnant woman's body has 6 IU/L to 70 IU/L of hCG. The concentration increases from 160 IU/L to 32,000 IU/L during the sixth week of pregnancy.

When should you take a pregnancy test?

Ovulation is the process in a woman's menstrual cycle when the egg is ready for fertilization. It occurs around the 15th day of the menstrual cycle. When a sperm fertilizes a mature egg, the fertilized egg then travels to the uterus through the fallopian tubes.

The egg implants in the uterine wall. Implantation triggers hCG production in the woman's body. The hormone is produced from the placenta's cells. A pregnancy test can detect trace hCG levels from the urine eight days following ovulation.

As more days pass, the amount of hCG increases in the blood and urine. Therefore, you're likely to get more accurate results if you take a test later with more hCG in the urine. It's recommended that you take an at-home pregnancy test on the day you expect to get your period.

Take the pregnancy test early in the morning as the urine is more concentrated during this time of the day.

How accurate is the pregnancy test?

An at-home pregnancy test can be very accurate if you follow the instructions on the packaging and interpret your results properly. If you do not understand or handle the test kit correctly, you'll get poor results.

Typically, all pregnancy tests have the same ability for hCG detection. However, their ability to determine if you're pregnant or not depends on the hCG levels in your body.

If you take a pregnancy test too close to the day of conception, the hCG levels in the body may be too low to support the chemical response. The pregnancy test won't detect the hCG, or the chemical reaction will be weak. Even if the test detects trace hCG levels, it might not clearly show that you're pregnant.

Some women also have irregular periods, while others do not calculate the date of their period correctly. Due to this, 10 to 20 women per 100 women are unable to detect the pregnancy on the first day of a missed period.

Many doctors also conduct a pregnancy test to confirm pregnancy in their patients. It is the same test as the one you would take at home. However, since doctors are usually more experienced, they are likely to get accurate results and interpret them correctly.

Your doctor may also conduct a blood test to confirm the pregnancy. They may also have reports from other tests or findings of the physical exam to determine if you're pregnant or not.
