PREGNANCY TEST RELIABILITY

KNOW THE RELIABILITY OF A PREGNANCY TEST
Pregnancy tests are they generally reliable? For their reliability rate, here are some indications about the effectiveness of urine pregnancy test and pregnancy test by blood. Every pregnancy test works on the same principle: the detection of human chorionic gonadotrophin (HCG or beta-HCG) hormone secreted when the egg attaches to the uterine cavity, about eight days after fertilization.
1 - Reliability urine pregnancy test

The reliability of a urine pregnancy test is consistent, since the test is considered reliable in 99% of cases. Subject to proper use [cf do when your pregnancy test], a positive urine test is generally considered reliable.
Indeed, it is very rare for a pregnancy test appears to be positive without early pregnancy, a urine test may also be considered infallible if it is positive in 99% of cases. By cons, a urine test may indicate negative results although pregnancy has already begun.
2 - Reliability test for pregnancy blood test

The reliability of a pregnancy test by blood is higher than that of a urine pregnancy test. This is by far the most effective since its reliability rate is 100%. After an appointment with your GP, it may prescribe a blood test at a testing laboratory. The principle is the same as for a urine test: detecting the hormone hCG (human chorionic gonadotropin) with increased reliability since the Beta-HCG hormone is present primarily in the blood before being excreted in urine.

best pregnancy test

The urine pregnancy test measures the presence of a specific hormone of pregnancy urine: human chronics gonadotropin or hCG (Human chorionic gonadotropin or human chorionic gonadotrophin). The amount of hCG in your body doubles every 2-3 days from implantation of the fertilized egg.

How and when to test?

The test can usually be done at any time of day. It need not be done with the first morning urine. However, avoid drinking too much liquid before the test. The tests today are very sensitive; you can start using them 9-10 days after fertilization (that is to say even before the first day of your missed period). If the result is negative, and if you suspect a pregnancy anyway, you must wait at least 2 days before re-testing because it may be that you did the first test too early.

PREGNANCY TEST DEFINITION

DESCRIPTION OF A PREGNANCY TEST
Definition Pregnancy Test A pregnancy test gives precise indications about the presence of a specific hormone: the human chorionic gonadotrophin (HCG or, or beta-HCG). This hormone is detectable about eight days after fertilization. Indeed, once achieved fertilization and the appearance of the egg, it remains free and is floating in the tube until it reaches the uterine cavity and bind via one of its ends. The cells of this end will then begin to secrete a hormonal substance (beta-HCG) to maintain ovarian secretions to the rules of no return: single condition that the egg remains attached to the uterine parodies.
This hormone chorionic gonadotropin (glycoprotein hormone produced during pregnancy, produced by the embryo soon after conception and later by the fibroblast - part of the placenta -), not present in women unmated, which is detected by the pregnancy test.
The amount of HCG double approximately every two days until the twelfth week of pregnancy before falling, it remains detectable in blood and urine throughout the pregnancy period.
