It's safe to say that before you proceed with the test, each woman defines one of the most important issues: how accurate are pregnancy tests Pregnancy tests - early diagnosis . The diagnostic value of urinary tests in some cases may reach 92-99%, but this fully depends on whether a study was conducted. To recommend a particular test system needs a specialist who can give practical advice qualified.

The reliability of the test results of urine

The accuracy of the test, its informative value in detecting pregnancy depends on several factors:

• what day of the cycle was made a study, whether the delay was the next menstruation;
• which it was used by test system, its sensitivity;
• We have complied with all the recommendations in accordance with the instructions in the study (such as the necessary time of the test, which should not exceed ten minutes);
• what time of day the woman made the test, since the highest concentration of hormones in the urine is observed only in the morning.

All these factors combine to affect the accuracy, reliability of test results. Since it is based on a reaction to the start of production of the female body hormone hCG, it is important to choose the right time for the test. Its production begins within days after the implantation of the embryo occurred. If a woman has decided to carry out the test before the start of the next menstrual period, it is impossible to calculate accurate results. The result of this test can be misleading name, since it is made too early, when the reagent can still detect the presence of the pregnancy hormone. Because one of the first defining moments that affects the accuracy of the test is its timing. The urinary test should be performed only after a week delay menstruation.

What is better to choose a test system

The most widely used tests in the form of test strips. The validity of the results is high when they are used correctly. The latest generation of tests that differ most accurately be deemed jet test systems. Even when the urine contains a minor amount of hCG test necessarily will result, which is a feature of the variety of tests. It contains the special particles which react with contained in urine pregnancy hormone hCG. Results can be obtained already within one minute after the test. It is an advantage of such a test system.

This type of test is called a jet, since it is sufficient to substitute a test of a urine stream. Women should not omit the test strip into the urine tank, without having to wait for the staining strip to ten minutes. Jet test makes it possible to obtain very quick results, and it will be very accurate. The only significant disadvantage of such a study can be called its value. Not all women can afford to buy the test system at a higher price, so are the most accessible tests. Tests of the latest generation are relatively expensive. It should be noted that their price is largely justified, given that you can expect to receive reliable results.

Such nuances diagnostic test using test systems should explain the woman when it comes to the selection test. The doctor may recommend the most convenient and accurate method for the diagnosis of pregnancy, and women have the choice depends on what will be the result. Accuracy inkjet test is high and is about 99%.

There is another kind of test systems - the diagnostic plates. They have two windows - one for urine enters the study, and another one can see the test result. This test system is also characterized by high accuracy, so experts recommend them for practical use.
