if pregnant the earliest way to find out if you suspect you are pregnancy test pass through. For 4 days, the fertilized egg begins to secrete a hormone called human chorionic ganodotropin (hCG). This hCG hormone spreads to the body's tissues in body water. It can be found in the blood at first and can be diagnosed in the urine after a very short time.

Pregnancy tests most are made with a urine sample because it is easier to collect from a blood sample. The presence of the hormone hCG is detected by many urine assay type methods. Most are based on a reaction between the hCG and the hCG antibody. A second reaction is absolutely necessary to ensure that the first reaction takes place. This reaction is often a color change. Some women prefer pregnancy tests at home. These are packages that can be purchased at the pharmacy.

Usually, these test tubes contain a urine-miscible solution. The results will vary from a few minutes to several hours, depending on the test. The result is a dark ring in the test tube if you are pregnant. The color may vary depending on the brand of the test.

If the results of pregnancy tests at the pharmacy are performed 10 days after the menstrual delay, the margin of error is only 5%. The most commonly used tests are urine-based. However, in some cases, blood tests are preferred to be more accurate and to be diagnosed earlier.
