Pregnancy test with soda
A pregnancy test with soda is a very affordable home method for determining a possible pregnancy. Talking about the early diagnosis of pregnancy when it is impossible to determine it by more informative methods, alternative methods are also widely used. It can be not only soda, but also the use of iodine, as an identifier of a possible pregnancy. Therefore, in order to talk about the effectiveness of the method, one must know the basic principle of its operation.
Basic principles of the test with soda
Speaking about the principle of the action of this method, it is necessary to understand first of all the chemical and physical properties of urine. Normally, urine has a relative density higher than water and has a slightly acid reaction. When a woman is pregnant, chorionic gonadotropin begins to appear in the urine, which changes the properties of urine, as well as other substances that have an alkaline reaction. This breaks the process of excretion of ammonia by the kidneys and the urine reaction becomes slightly alkaline. But a change in the urine reaction is possible with other kidney pathologies. It can be an inflammatory disease of the kidneys - pyelonephritis, as well as cystitis, urethritis, glomerulonephritis. Changing the reaction of urine is also possible with the consumption of products with alkaline containing, which include carbonated drinks, coca-cola, fried foods. Therefore, when carrying out the test with soda, it is necessary that the above factors do not affect the state of the woman in any way, since in this case the test will be uninformative.
What is the principle of the test? Soda is an alkaline component, which when reacted with an acid forms a reaction in the form of hiss. If soda is added to the urine of a healthy person, then it will hiss because of the acid reaction of urine. In pregnancy, the reaction changes and interaction will not occur, so soda will simply precipitate. This is the main diagnostic feature, which is taken into account when carrying out the test with soda.
Also there is use as an additional component of iodine. If iodine is added to such a solution with soda, then it must spread over the surface of the liquid, since it has a high surface tension coefficient. In pregnancy, the relative density of urine can change, which contributes to a change in the surface tension of the fluid. Such changes will have a characteristic picture - if you drip iodine in your urine, then a drop of iodine will not spread as normal, but will look like a single drop placed above, like a drop of oil in the water. This is the main principles of the change in urine during pregnancy, which allow for the diagnosis of pregnancy at home.
Methods of testing with soda during pregnancy
For a higher degree of reliability of the test with soda, the correct technique of sampling urine is necessary. To do this, you need to collect only the morning portion of urine, which contains the maximum amount of hormones and biological substances that contribute to changing the properties of urine during pregnancy. You need to take half a glass of urine and pour in a teaspoon of soda, then you can not stir, if the solution hiss, then you are not pregnant. A home pregnancy test with soda is exactly what is convenient in that it can be done at home. A pregnancy test with soda and iodine should also be done with the morning portion of urine. You can take as a basis a slightly different modification - with a drop of soda you need to drip onto a sheet of paper moistened in urine and if iodine changes color, then there is no pregnancy, and if it remained orange, then chances are there is an embryo.
The reliability of the pregnancy test with soda is difficult to assess, because there are many subjective factors that can affect the deviation of the result. But speaking about this, taking into account also the responses, we can say that its reliability is less than 50%, that is, in the presence of pregnancy, it can give a false result with probability one to one. Therefore, it is better to confirm such a test with a pharmacological pharmacy test that reveals the level of chorionic gonadotropin.
Reviews of the test with soda for pregnancy indicate that its effectiveness is doubtful. There are many women who have tried this test without pregnancy, and soda hissed, but when ovulated she did not hiss. There is also confirmation, when the soda sediment was confirmed by two strips of the present test. Therefore, it is difficult to judge the effectiveness of this method of diagnosing pregnancy
A pregnancy test with soda is a very simple and affordable home test. But its effectiveness is very low, which is explained by many subjective factors that can affect the properties of urine. But in any case, in emergency situations, you need to remember about this method, and believe it or not - decide for yourself.
