Baking Soda Pregnancy Test

Baking soda has been used traditionally to determine pregnancy and is still used by many across the world for a DIY pregnancy test. It is a simple, low-cost, and convenient home-based method to detect the hCG hormone (pregnancy hormone) in the urine. Find out how this simple everyday ingredient can tell you whether or not you have conceived.

How Does It Work?

The human chorionic gonadotropin or hCG is present in the urine during early pregnancy (1). Baking soda can be used to check its presence in the urine. The reaction of baking soda with urine tells you whether or not hCG is present in it. If it is present, you are pregnant.

How To Perform This Test?

For this DIY pregnancy test, you would require:

  • Baking soda
  • Two dry cups, mark them as cup A and cup B
  • A sample of fresh urine

Follow these steps to test for pregnancy:

  1. Collect urine in cup A. You may directly urinate into it
  2. Take cup B and add a spoon of baking soda
  3. Now add the mixture of cup B into cup A
  4. Wait for a few minutes to notice the reaction

Note: hCG is easily detected in the urine when it is fresh. That means, use the urine which has been in the bladder for several hours, preferably the first one in the morning.

Interpreting The DIY Pregnancy Test Results

  • If you find a fizzy or bubbly reaction in the cup, it means the result is positive, which means you are pregnant.
  • If there is no reaction in the cup, then the result is negative, which means you are not pregnant.

Sometimes, doing the test at the wrong time could give you a false-negative result when the actual outcome is positive. Hence, it is essential to know when to perform the test to get the correct results.

When Should You Do The Test?

Your body produces hCG only after implantation, which occurs a week after ovulation. So the best time to perform the baking soda pregnancy test is a week or more after your missed period. Doing the test early might give you a negative result. In that case, you can perform the test again at the right time (2).

Is The Baking Soda Pregnancy Test Accurate?

There is no evidence to prove that the baking soda pregnancy test is accurate. Some women get correct results, while some may not. At times, you may get a negative result the first time, followed by a positive result the second time. So it can be said that baking soda pregnancy test has 50% accuracy.

Nonetheless, it is popularly used by many women in various countries, as it is a cost-effective and harmless way to determine pregnancy. But for 100% accurate results, you may want to go for a pregnancy kit bought at the store or get tested at a doctor’s clinic.
