Blood analysis
Important! In order to evaluate the result of your studies when observing in dynamics was correct and comparable, it is recommended that repeated studies should be conducted in the same laboratory at the same time, because different research methods and units of measurement can be used in different laboratories.
The reliability of the results of laboratory studies depends on many factors, among which the proper preparation for analysis and method and time of sampling is important
1.Food.
– It is recommended to give blood in the morning, on an empty stomach, from 8 to 11 hours.
– Do not eat greasy food a few hours before the test, preferably not eat for 4 hours – a high concentration of lipids in the blood can interfere with any study.
– To determine the parameters of the lipid profile and glucose, the blood is taken strictly on an empty stomach, after 12-14 hours of starvation.
– Shortly before taking blood, drink 1-2 glasses of ordinary still water, this will reduce the viscosity of the blood, and it will be easier to take a sufficient amount of biomaterial for research, in addition, it will reduce the likelihood of clots in the tube.
2. Therapeutic drugs.
– If you are taking any medications, you should consult your doctor about the advisability of performing the test during treatment and about the possibility of canceling the drug on the eve of the study.
– In connection with this, it is recommended that when passing tests on the background of taking medications, indicate this fact in the form.
– Blood is taken before taking medication !
3.Physical exercises.
In order to exclude the influence of physical exertion and psychoemotional factors on the day of testing, it is recommended:
– Do not have any physical exercises.
– Exclude increasing of emotional stress.
– Refrain from drinking alcohol for 72 hours before taking the test.
– Do not smoke at least for 30 minutes before taking blood.
– A few minutes before taking blood, take a comfortable position (sit down), relax, calm down.
4.The physiological condition of a woman.
For a number of hormonal studies, the phase of the menstrual cycle is important. To obtain the correct results of the tests, it is recommended:
– Specify the optimal days of the menstrual cycle (or gestation period) for the delivery of A-follicle-stimulating hormone (FSH), luteinizing hormone (LH), progesterone, estradiol, androstenedione, 17-hydroxyprogesterone, prolactin, and specific markers: inhibin-B and antimueller hormone.
– When you fill out the form, you must specify the phase of the menstrual cycle or gestational age – this ensures that reliable results of the study are obtained with the correct ranges of normal (reference) values.
