Tests – already the act itself is unpleasant, and here and at 7 in the morning to get up, trudge to the clinic. Sometimes even for Breakfast impossible. And all for what? To a month the doctor sent for re-study, which again show the same thing. Is it really so necessary? Is there any way you can simplify your life? Let’s deal.
1. Why tests take only in the morning?
It’s more convenient. During the day, changes in the blood level of erythrocytes, leukocytes, platelets, and certain hormones. Therefore, the results of the same analysis, taken morning and evening, will be different. The doctor will be difficult to compare them.
And some studies can only be performed on fresh biological material. For example, if you need to determine the clotting factors, the blood should be stored for no longer than 4-6 hours. Therefore, when the analysis comes in the morning, the laboratory knows that the sample is not deteriorated.
If you do not want to come to the clinic in the morning, you can go to a private lab – they see patients throughout the day. But if one analysis will be required to surrender several times, come to the lab at the same time.
2. Do I have to be hungry?
In General, it all depends on the type of analysis. Some food has no effect: recent studies show that the level of cholesterol and lipids does not change after a meal. But better not to eat fats – they make blood turbid for a few hours.
British and American scientists believe that before the clinical analysis of blood do not have to starve – on the results will reflect only sweet food and, again, greasy.
But for now, in most clinics is the rule tests may only be on an empty stomach. It’s easier and more convenient than to deal separately in each type of research.
3. What else not to do?
To smoke, drink anything except water, chew gum, exercise, taking certain medications and Supplements (here it is necessary to consult with your doctor). All of this can affect the results. From alcohol , refrain the day before delivery.
4. I have had blood tests and they showed that everything is normal. Why do it again?
If the survey did not reveal abnormalities, it is also an important result. Sometimes, the doctor may find the disease just a process of elimination. In other cases, negative results allow to make a prediction: if a pregnant woman did not find urogenital infections, so it’s likely that the pregnancy will proceed smoothly. And it so happens that they need to control. For example, if you compare the same tests, commissioned at different times, we can calculate the duration of the disease. And finally, sometimes you need to pass the examination several times in order to obtain reliable results: the accuracy of the first research on parasites is only 50%, and the third is already 99%.
5. And can anything get infected when giving blood?
No, it is possible. If the clinic uses disposable or sterilized according to the standards of the tools she will take away the license.
