The analysis of blood on hCG (human chorionic gonadotropin) at the moment is one of the most reliable methods of diagnosing and determining pregnancy. This hormone is produced by the embryonic coat during the entire period of gestation, and the level of its concentration varies depending on the term. The highest figures are observed for a period of 10-12 weeks.When a woman receives a referral for this study, the most common question is how to donate blood to HCG. After all, this is one of the most exciting moments, so you want to prepare for it, as expected. Indeed, such a diagnosis requires special conditions, which significantly increase the reliability of the results. The main rule that should be remembered for every woman going to the laboratory is that the blood is given for hCG on an empty stomach and only! Why is it so important? The fact is that hormones are subject to absolutely any factor from the outside, as a result of which the figures can vary in one direction or another. Accordingly, such an analysis can not be considered reliable, and the consequences can lead to an incorrect diagnosis. That's why every pregnant woman needs to come fully to the matter and get all the details about how the blood is given to HCG.
What else does the chorionic gonadotropin say?
The definition of the level of this indicator can provide information about some other circumstances concerning the future child, namely:
- Presence of an ectopic pregnancy.
- Lack of placental nutrition.
- The presence of risks that contribute to miscarriage.
- Mature pregnancy.
- Presence of defects in the fetus.
In addition, excessively elevated rates may indicate toxicosis, diabetes, multiple pregnancy and late gestosis. These circumstances once again underscore the fact that it is necessary to know how the blood is delivered to HCG.
What is the difference between a normal pregnancy test?
Strange as it may seem, urine testing is conducted with the determination of the same index, i.e., HCG, but their effectiveness is not so high as in blood. More accurate results they can show at later stages of pregnancy. This is due to the fact that in the blood the concentration of hormones is several times higher than in the urine.
Even if you learned how to donate blood to HCG, and did everything right, sometimes there are errors. Most often it happens when a woman does not wait for a delay in menstruation. It is ideal to conduct such a study on the 10th-12th day from the moment of conception.
If the blood on HCG is negative?
Sometimes, with obvious signs of pregnancy, the analysis shows a low level of the indicator, which may indicate an ectopic location of the embryo. If the results after high figures suddenly began to show negative, then you can suspect a beginning miscarriage or fading of the fetus. In both cases, an immediate hospitalization of a woman in a hospital is required.
