Types of Pregnancy Tests and How Soon You Can Get Accurate Results

For new moms or women who are wondering whether they might be pregnant, taking a pregnancy test is the best way to find out. Relying only on early symptoms may not be enough to confirm pregnancy.

That’s why it’s always a good idea to visit a clinic or healthcare provider for a proper pregnancy check. Not only will you be examined by a medical professional, but the accuracy of the test also depends on the quality of medical equipment used.

However, if you’d like to try a home pregnancy test first, Intouch Medicare has some simple tips to help you do it correctly.

Types and Methods of Pregnancy Testing

Refer to the hCG levels table from: https://americanpregnancy.org/getting-pregnant/hcg-levels

Pregnancy Test Using Blood Sample

A blood pregnancy test measures the level of human chorionic gonadotropin (hCG) in the blood — a hormone produced by the placenta or gestational sac specifically during pregnancy.

The results are interpreted based on the hCG level as follows:

• ≤ 5 mIU/mL: Not pregnant
• 6–24 mIU/mL: Indeterminate – pregnancy cannot be confirmed yet. The test should be repeated after 48 hours. If the hCG level doubles, it can confirm a viable pregnancy.
• ≥ 25 mIU/mL: Pregnancy confirmed

A blood pregnancy test can usually detect pregnancy as early as the 3rd week from the first day of your last menstrual period (LMP), or about 7–12 days after fertilization.

Pregnancy Test Using a Home Test Kit

• A home pregnancy test works by detecting the level of human chorionic gonadotropin (hCG) in urine.
• Most test kits can detect this hormone when the hCG level reaches 20–50 mIU/mL, depending on the sensitivity of each brand.
• It is recommended to take the test on the first day of a missed period, especially for women who have a regular menstrual cycle. If your period is late and you also experience symptoms such as breast tenderness, nausea or vomiting, unusual fatigue, changes in appetite, or frequent urination, it may be a good time to take a pregnancy test.

Pregnancy Test Using Ultrasound

• An ultrasound pregnancy test detects the gestational sac using high-frequency sound waves.
• There are two types of ultrasound: abdominal and transvaginal. Transvaginal ultrasound provides a clearer view of the gestational sac and internal structures, especially in early pregnancy, compared to abdominal ultrasound.
• The gestational sac can usually be seen at around 5–6 weeks of pregnancy (counting from the first day of the last menstrual period, LMP).
• Fetal heartbeat activity can typically be detected at 7–8 weeks of pregnancy (from the first day of LMP).

Ancient Pregnancy Test Methods

In ancient times, women who missed their periods and experienced symptoms such as breast tenderness or nausea would use a unique method to test for pregnancy. They would urinate on wheat and barley seeds for several days.

• If the barley sprouted first, it was believed the baby would be a boy.
• If the wheat sprouted first, it was believed the baby would be a girl.
• If neither sprouted, it indicated that the woman was not pregnant.

Scholars note that high levels of estrogen in the urine of pregnant women may have promoted the growth of the seeds.

Tips for Using a Home Pregnancy Test Correctly

A home pregnancy test detects human chorionic gonadotropin (hCG) in urine, a hormone produced only during pregnancy. When used correctly, home pregnancy tests are highly accurate (up to 99%).

Different brands may offer various testing formats, such as:

• Dip test – dipping the strip into a urine sample
• Drop test – placing a few drops of urine on the test area
• Midstream test – urinating directly on the test stick (the easiest and most popular method)

The sensitivity level of the test also matters. A lower sensitivity number (e.g., 20 mIU/mL) means the test can detect pregnancy earlier compared to a less sensitive one (e.g., 50 mIU/mL).

For the most reliable result, it’s best to follow the instructions carefully and test with the first morning urine, which usually contains the highest hCG concentration.

Conclusion

As you can see, there are many different pregnancy testing methods available, each offering flexibility and convenience for women. However, the most accurate way to confirm pregnancy is through a blood test at a medical clinic or laboratory. If the result confirms pregnancy, you can begin your antenatal care right away.
