Platelets are called blood plates - they do not have a nucleus, participate in the clotting process. In the analyzes have the designation PLT.These cells are designed to provide regeneration of damaged tissues, feeding the walls of blood vessels. The number of platelets found in humans has a norm, but in women this indicator may deviate.
What is the norm of platelets for women
The functions of these plates are very important for the proper functioning of the human body. The duration of their lives in women and men is about 7-10 days. If this cycle is broken, and the PLT is not disposed of, they accumulate, this leads to a thickening of the blood, the formation of thrombi. The normal level in a healthy person is in the range of 200-400 thousand / μL.Their volume may decrease due to menstruation, during pregnancy, therefore the female index is slightly lowered - 150-400 thousand / μl.
This decrease in the platelet count in the woman's blood occurs at the time of blood loss, but already at the next analysis the level should come to the previous value. In a healthy female body, the average performance should be as follows:
- up to 1 year - 120-300;
- 1-4 years - 150-300;
- 15-18 years - 180-340;
- 18-69 years - 180-320.
In the general blood test
To calculate the level of platelets, usually a general blood test is performed. In the results, the volume of the blood platelets will be denoted by the abbreviation PLT.During pregnancy, girls usually take a coagulogram. The last analysis has a purpose for determining the PLT level, and the general analysis presents data on all the elements. For a coagulogram, blood is taken from the vein. To hand over both analyzes it is necessary on an empty stomach in the morning.
By Fonio
There are several variants of tests that help to determine the volume of blood platelets. One of them is the Fonio method, which makes it possible to use automatic counters for calculating PLT.It is only necessary to use such reagents:
- dye Romanovsky-Giemsa;
- 14% magnesium sulfate;
- fixation of Main-Grunwald or Leishman.
On a finger, women make a puncture, a drop of blood is mixed with magnesium sulfate. From the resulting mixture, smears are prepared, which are then dried and stained. Then the counter counts 1000 red cells in the smear for a certain period of time and displays a relative amount. Absolute platelet count in women is deduced so - the result is multiplied by 1 μl of erythrocyte count and divided by 1000.
Platelet aggregation rate
These blood cells are the smallest in the human body, but perform one of the most important functions. If platelets are less than normal, this affects clotting, resulting in heavy blood loss. Avoid this helps the process of aggregation( gluing) of cells between them, forming a "stub"( thrombus).However, if there is an increased norm, this leads to a thickening of blood, the formation of blood clots inside the vessels, which provokes negative consequences for human health. In the results, the probability of such a process is called thrombocrit.
The norm in women is measured by the rate of formation of large aggregates by the stopwatch, as a rule, this occurs in 10-60 seconds. This indicator may be different in pregnant women. The state of reduced aggregation is due to the low content of platelets in the blood in a woman, this factor must be taken into account when preparing for childbirth. The indicator can be increased for toxicosis, loss of fluid due to diarrhea, frequent vomiting. With further growth, thrombus formation is possible, which in the early stages leads to miscarriage.
The norm in women with fetal growth is aggregation at the level of 30-60%.The doctor can prescribe a study with:
- infertility treatment;
- before a planned pregnancy;
- reception of contraceptives.
