What does elevated fibrinogen mean? The rate of fibrinogen in pregnancy
Fibrinogen is a special protein in the blood serum,which participates in the process of coagulation. If necessary (any bleeding), it breaks up into separate strands (this happens under the influence of another protein - fibrin). With the help of these threads, the blood coagulates and the bleeding stops. Reduced or elevated fibrinogen can speak about some deviations. Its norm in the blood varies in the range from 2 to 4 g / l. In some physiological processes, the rate of this indicator may increase. For example, fibrinogen is elevated in pregnancy to 6 g / l.
What else can evidence increased fibrinogen? A sharp increase in this indicator in the blood can speak of the following pathological conditions:
- myocardial infarction;
- various oncological diseases;
- acute infections and inflammatory processes;
In any case, the exact reason for the increasefibrinogen in the blood will set the doctor. To clarify the diagnosis will need some more surveys. Also, elevated fibrinogen can be observed after recent injuries, burns, surgery and as a result of taking certain drugs. For example, this figure is increased when taking estrogens.
- insufficient amount of vitamin B12 or C;
- severe toxicosis in late pregnancy.
Norms of fibrinogen in the blood:
1.25-3 g / l
2-4 g / l
Pregnancy 3rd trimester
up to 6 g / l
Blood for fibrinogen is surrendered from the vein in the morningon an empty stomach, as a last resort, from the moment of reception of food to delivery of the given analysis it is necessary to sustain not less than two hours. Blood is taken into a specially treated test tube with the addition of a reagent. After this, several times it is carefully turned over to better mix the reagent with the blood. Only in this case it is possible to obtain a reliable analysis, and it must be done no later than two hours after the blood donation.
