Does blood analysis for pregnancy need fasting?

A blood test for pregnancy does not require fasting. Fasting for pregnant women is generally considered safe and does not have any negative impact on the fetus or pregnancy, as we find that when the woman confirms that pregnancy has occurred and during follow-up with the specialist doctor, some necessary medical tests must be performed during pregnancy to check on the health of The mother, as well as the fetus, and that the pregnancy is proceeding in a normal way, and within the same scope, we find that the blood test for pregnancy is one of the tests that do not require fasting in advance, as well as the lack of preparation or preparation in any way to perform this analysis, and here it should be noted that there are some special tests that are required by the doctor and are performed Her work for a pregnant woman needs fasting, but this is what the doctor determines according to the need of the situation.

What is the period of fasting required before blood tests?

Medical examinations, as well as the period of fasting required for each type, differ, which requires pre-fasting before them, but in general, we find that most of these tests require fasting from food and drink before them, at least 8 hours, with the exception of drinking water. To come to mind and get confused, are they among the things that are allowed to be eaten prior to the examination or not, including the following:

Drinking water

Drinking coffee

Drinking coffee of all kinds and forms before performing any medical examination is strictly prohibited, for several reasons, the most important of which is the effect on the accuracy of the results.

• HCG Hormone Quality Assay: It is known as the human gonadotropin hormone, and this analysis is done in the laboratory after the menstrual period is ten days late by drawing a sample of blood and examining it. Therefore, it can be said that this type of analysis is the best option for those who want to know whether a pregnancy has occurred or not.
• Quantitative or digital HCG examination: This type of test is more accurate than the previous one, as it is based on measuring and tracking the level of pregnancy hormone secretion in the blood, even no matter how small its percentage, which leads to the doctor’s assistance in a more comprehensive way by determining the age of pregnancy as well as its health and whether it is proceeding in a natural way or not, as it increases The percentage of this hormone doubles every day from the previous one until it reaches its peak ten weeks after conception, and then begins to decrease gradually, and if it disappears, this may indicate a loss of pregnancy.

Other analyses

After the blood tests and their types were identified, we find that there are other types of tests, which are as follows:

• Urinalysis: It is considered one of the easiest types of analyzes that are performed to confirm pregnancy, as it is done at home a week after the missed period by buying it from the pharmacy and following the steps listed on the package, and its result is one of the documented results by 97%, so we find that when the appearance of The result is positive, for surely there is pregnancy, but if it is negative, it can be performed after several other days, because it may not appear at the beginning of pregnancy and because the percentage of this hormone increases with the passage of days, it is also recommended to do it in the morning and not drink a lot of water before doing this examination.

Urine examination and its relationship to the menstrual cycle

A urine test is done at home to confirm whether pregnancy is present or not, by relying on the appearance of the hormone HCG that is secreted in the urine, and this analysis can also be done two or three days after menopause, but there are two cases to choose the most appropriate time for analysis after absence Menstruation can be listed as follows:

• In case Regular menstruation: We may find that the best time to conduct this examination is after a full week of delayed menstruation.
• In the case of irregular menstruation: A woman has to delay doing a pregnancy analysis, as the delay could be due to irregularity and not due to pregnancy, so we find that the most appropriate time for her in this case is after a month and a half has passed from the date of her last menstruation prior to that, and then this special hormone will appear pregnancy in urine.

Blood test and its relationship to the menstrual cycle

The blood test differs from urine, as we find that the blood analysis is done by drawing a sample of blood and examining it, in order to ensure the appearance of the hormone HCG and measure its proportion in the blood of the pregnant woman, and in order to achieve this, the best time for this analysis can be presented in one of the two cases after the delay of the menstrual cycle in the following :

• In case Regular menstruation: Pregnancy can appear in the blood analysis from the first day on which pregnancy occurred, but in the case of regular menstruation, we find that the best time to do this analysis is one day after the missed period for the scheduled time.
  
• In the case of irregular menstruation: In this case, the most appropriate time to take a blood test for pregnancy is about a week after the expected date of the menstrual cycle, and it should be noted here that making a blood test for pregnancy in the laboratory is more accurate and gives reliable and confirmed results more than other home urine tests .

Factors affecting pregnancy test

We also talked in the past that one of the ways by which one can know whether or not pregnancy is a home test, and since this type of doubt and uncertainty in the results is due to the lack of sufficient knowledge of some women about the correct method of use, but it was found that there are other factors that may affect the accuracy of the pregnancy. As a result of pregnancy, and in this regard, these factors will be presented in the following lines:

• The right time to do the analysis: Which is the best time to do this examination, as we find that the best choice is in the morning, as a result of the fact that the pregnancy hormone has the highest concentration and concentration in the blood in the morning, which leads to more certain results.
• Previous miscarriage: Where we find that having a prior history of recent miscarriages may cause misleading test results, because the miscarriage may leave a trace of the presence of a percentage of the pregnancy hormone in the blood.
• Take medicines: There are some regular medications that we do not find any effect on the pregnancy hormone analysis such as Advil, but there are also other types of treatments that greatly affect the pregnancy hormone such as taking fertility drugs, of which we find HCG injections.
  
• Presence of cancers: When a pregnant woman is exposed to some cancers, and the reason for this is that there are some types of cancer that secrete the pregnancy hormone in the blood, which in turn will affect the result of the pregnancy hormone and give improper results.
  
• Hurry up to take the test: We may find that when you use a pregnancy analysis early, it may lead to incorrect results, as the pregnancy may be in its early stages and the HCG hormone has not yet reached the blood, which results in the absence of a positive pregnancy result.
  
• Rare medical conditions: There are some medical cases that can show adverse results of pregnancy, and the reason for this is that some of these cases work on the secretion of the pregnancy hormone in the blood, among which we find a pituitary disorder.
  
• molar pregnancy: We may find that it is among the cases of pregnancy, in which the fetus grows inside the mother’s womb in the form of a grape cluster and becomes deformed, and surgical intervention and abortion are required.
