Pregnancy tests can generally be done at home, making it the easiest and quickest method. However, there are many questions that arise when using it in real-life situations. Some of the most frequently asked questions are: How many types of pregnancy tests are there? Which one is the best? When is the best time to test for accurate results? And how do you read the pregnancy test results? In this article, we will answer all these questions.

Am I pregnant? How can I know for sure?

Which pregnancy test gives the most accurate results? The most accurate method is a blood test to check the Beta-hCG hormone levels. The results can be obtained in about 1-2 hours, making it ideal for those who want fast and accurate results.

When is the best time to take a home pregnancy test? It is recommended to test in the morning right after waking up, as the urine is fresh and most concentrated. However, testing at other times of the day can still yield accurate results, as the key factor is fresh urine.

What should you do after confirming pregnancy? After confirming the pregnancy, it is important to visit a doctor for prenatal care, undergo a physical examination to prevent any complications for both the mother and the fetus, and to receive expert advice on how to take care of yourself during pregnancy.

Pregnancy Test

A pregnancy test or pregnancy test kit is a device that allows you to check for pregnancy on your own and can be purchased at most pharmacies. The principle behind the pregnancy test is to detect the hormone HCG (Human Chorionic Gonadotropin), which is produced by the placenta after fertilization occurs, typically about 6 days later. The level of this hormone is highest during the first 8-12 weeks of pregnancy.

Pregnancy tests can be used for both natural pregnancies and pregnancies resulting from assisted reproductive technologies, such as IVF (in vitro fertilization), ICSI (intracytoplasmic sperm injection), and IUI (intrauterine insemination)

When should I take a pregnancy test?

A frequently asked question is when is the best time to take a pregnancy test for the most accurate results?

For those trying to conceive naturally or undergoing assisted reproductive procedures, it is recommended to take a pregnancy test at least 14 days after intercourse.
For individuals undergoing IVF (in vitro fertilization) or ICSI (intracytoplasmic sperm injection), the test should be taken 14 days after embryo transfer.
For those undergoing IUI (intrauterine insemination), the test should be taken 21 days after the insemination.

Pregnancy tests can be purchased at convenience stores or pharmacies. It is important not to test too early because if the result is negative, it can cause disappointment and stress. In some cases, the result may take longer to show. Therefore, it is best to take the pregnancy test at the time advised by your doctor.

Signs that indicate pregnancy

Missed period: If your period is usually regular and suddenly stops, it may indicate that you are pregnant.

Nausea and vomiting: These symptoms typically occur about a month after conception, but some people may be pregnant without experiencing nausea or vomiting.

Breast tenderness: Due to increased blood flow to the breast area, causing swelling, tenderness, and heightened sensitivity, similar to what happens before menstruation.

Frequent urination: As the body increases blood flow to various areas, the kidneys expel more waste from the body.

Constipation: Hormonal changes slow down the digestive system, and the growing uterus may put pressure on the intestines.

Mood swings: Feelings of irritability or anger may occur as the body adjusts to hormonal changes.

Many wonder how to distinguish between pre-menstrual symptoms and pregnancy symptoms. You can read more in the article 'What are the symptoms of PMS, and how do they differ from pregnancy symptoms?

Methods of pregnancy tests: How many types are there?

How to perform a pregnancy test by yourself

  • Test Strip

The pregnancy test strip type comes in the form of a strip that you dip into urine. Some brands may include a small cup for collecting urine. To use the dip test method, collect urine in a container and then dip the test strip into the urine for about 3 seconds. After removing the strip, set it aside and wait for the result after approximately 5 minutes. It's important to read the instructions on the product label for proper use of the dip test.

  • Pregnancy Test Cassette
  • Digital Pregnancy Test

The recommendation for using a home pregnancy test is:

The most convenient and popular type of pregnancy test is the midstream pregnancy test, also known as a pregnancy test pen. It is easy to use and requires minimal equipment. On the other hand, the dipstick pregnancy test has the advantage of being more affordable than other types. Regardless of the type, the results are quite accurate, with an accuracy rate of around 98%. For the best results, it is recommended to use morning urine for the pregnancy test. However, this does not mean that urine from other times of the day will yield poor results. The most important factor is that the urine used should be fresh.

Things to know before using a pregnancy test:

A pregnancy test kit can be stored at room temperature, up to 30°C, and should be kept away from direct sunlight and moisture. Once the test kit is removed from its packaging, it should be used immediately for the most accurate results. If not used immediately after opening, it can be kept for up to 1 hour. If exposed to moisture, the kit's effectiveness can be reduced, which may lead to inaccurate results. When retesting, it's recommended to wait at least 2-3 days between tests.

Here are some tips for using a pregnancy test:

  • Read the instructions: Before using the test, carefully read the user manual to ensure you're following the correct procedure, which helps minimize errors.

  • Check the expiration date: Always check the test's expiration date before use. Using an expired test may lead to inaccurate results because the chemicals used in the test may have degraded.

  • Wait for a missed period: It is best to use the test at least 7 days after a missed period. This is because your period may be delayed due to stress, so testing too early might give unreliable results.

Interpreting pregnancy test results

Interpretation of Pregnancy Test Results One line appears on the pregnancy test If one line appears at the "C" section only after using a urine pregnancy test, it indicates a negative result, meaning "likely not pregnant". This could either mean the woman is not pregnant, or she may be pregnant but the test was not sensitive enough to detect it yet. Two lines appear on the pregnancy test If two lines appear, or if two faint lines appear at both the "C" and "T" sections, it indicates a positive result, meaning "likely pregnant". If the line at the "T" section is faint, it's recommended to wait another 2-3 days and test again. No lines appear on the pregnancy test If no color appears, or if no lines appear at all, or if one line only appears at the "T" section, the result is invalid. This indicates that the "pregnancy test kit is faulty" or that there was an error in the production process, or the test kit has expired. If no line appears, the test result cannot be used, and it’s necessary to retake the test.


How accurate is the pregnancy test result?

"Each brand of pregnancy test claims a high level of accuracy. However, there are several factors that can cause discrepancies in the results, such as:

  • Timing of the test: Testing too early may result in inaccurate results because the level of hCG (human chorionic gonadotropin) in the urine may not be high enough to detect pregnancy.

  • Sensitivity of the test: Different brands of pregnancy tests have varying levels of sensitivity to hCG. Tests with lower sensitivity may produce a negative result even if pregnancy has occurred.

  • Concentration of urine: If the urine is diluted due to drinking too much water before the test, it may affect the concentration of hCG in the urine and reduce the accuracy of the test.

  • Use of certain medications: Some medications, such as diuretics or antihistamines, may contain hCG or affect hormone levels, potentially influencing the test result.

How many days does it take to get the result from a pregnancy test?

There are various methods for pregnancy testing, and the results may vary depending on the method used:

  • Pregnancy test using an over-the-counter test kit: This method provides the fastest results, typically within 5-10 minutes. It is convenient and easy to use.

  • Pregnancy test through a blood test at a healthcare facility: Results are available within 1-2 hours, and the results must be read and interpreted by a medical professional.

  • Pregnancy test using a transvaginal ultrasound: The results are available immediately after the test, and the doctor will analyze the images produced.

It is recommended that if you want to find out if you are pregnant, you can start with the simplest and most accessible method, which is purchasing a pregnancy test kit. However, if you have concerns or doubts about unclear results, it is best to visit a nearby healthcare facility to consult with a doctor.

Conclusion

In conclusion, when pregnant, we can test for pregnancy by ourselves. There are four types of pregnancy tests: dip tests, cassette or drop tests, pen-type or urine-stream tests, and digital tests. All four types are similarly accurate. Some women may experience symptoms or signs that resemble early pregnancy, such as missed periods, breast enlargement, fatigue, or lower abdominal pain.

If you have these symptoms, you can use a pregnancy test to check for pregnancy. However, if you are still unsure, you can visit a healthcare facility for a blood test to confirm the pregnancy.

Body Mass Index calculator

Being overweight or underweight can reduce fertility, so it is important to keep your body weight within the normal healthy range.

Body Mass Index (BMI) is an indication of your body weight and can be calculated by dividing weight by height. You should aim for a BMI of between 20 and 25, as this will optimise your chances of conception.

Woman’s BMI below 19

Even in these modern times, nature knows best. If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

Being underweight

If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

BMI’s greater than 30

This can reduce fertility by 50%. Pregnancy for women with a 30+ BMI is often associated with problems such as maternal diabetes, high blood pressure, big babies and increased risk of caesarean section.
