Platelets - blood cells that form a system of its collapse, and have many other important functions in the human body. Platelets are identified in the analysis of blood - PLT.
Where to find the rate in the analysis results
In addition to the hemostatic function of platelets themselves as a unit cell, are involved in vascular nutrition operate antiviral properties, are also involved in maintaining immunity. They are formed in the bone marrow. Compared with leucocytes, in the formula of general blood analysis more of them 50 times.
Platelets - cells are special, they are able to change, adapt, transmit the necessary substances endothelium, and only in severe emergency rescue situation processes - to form clots, thereby closing the affected area for bleeding. Hence their name. Restoration of damaged blood vessels - this is just one of the possibilities of these cells.
Platelets designation assays are PLT. The KLA platelet count ranges from 150 thousand. to 450 thousand. in 1 ml plasma. Small size (2-4 microns) are the smallest blood cells are essential in its own way.
The structure of the cell nucleus is absent, they have the shape of a sphere, simply referred to as blood platelets. With age, any person changing their number, and time has an aging effect, just as in the physical body.
Occurs vasoconstriction, cell movement may be difficult. Therefore it is especially important to get tested at least once every six months, but preferably every 3 months. This is a quick and inexpensive procedure.
As denoted
Patients are asked, what is the designation of platelets in the blood test. Received the form on hand a table with numbers and abbreviations - do not get lost and find peace with the abbreviation in capital letters - the PLT and compare your results with the norm. If the form is in Russian, just move the view of "platelets" line.
What does it mean platelet count
The most important and important rule - to be tested on an empty stomach (wait at least 12 hours after the last meal). Blood sampling is carried out:
- from the vein;
- from the finger.
Reducing the total number of particles - thrombocytopenia. Fluctuations from 50 thousand. to 150 thousand. in humans appear slightly: bruising, hematoma. Pay special attention if the index fell below 50 thousand. An urgent need to take action and seek the cause of the decrease rates.
There are:
- Spontaneous bleeding gums (periodontitis, periodontitis);
- nosebleed;
- internal bleeding;
- disorders of the immune system.
This is facilitated by:
- alcohol abuse;
- a deficiency of vitamin B12;
- bacterial infections;
- lesion spleen cells and liver, etc.
The first symptoms of platelet decline are:
- weakness;
- nausea;
- chronic fatigue.
Thrombocytosis - increasing the total number of platelets, the formation of dangerous blood clots, hyperactivity in their bonding together.
Men and older people figures may be higher than that of women and children.
The first main problem, which is harmful to the body, - dehydration.
Increased blood cells may also be due to the use of fast food, too fatty foods, foods with a large amount of sugar.
Gradually develop such serious diseases as:
- leukemia;
- diabetes;
- renal failure;
- cirrhosis of the liver;
- stroke, etc.
Other platelet indicators
If large deviations from the norm will still have to carry out additional research, but the UAC will help in time to pay medical attention to changes in the patient's body. The therapist guides the patient to a hematologist, a medical specialist, who will help to understand and study the blood abnormalities.
should conduct additional analyzes to better diagnosis:
- Blood coagulation (hemostasiogram) - clotting rate of biomaterial.
- Activated partial tromboplastikovoe time designated APTT - coagulation pathway.
It turns out that not only the number of cells is important, but also the rate of their formation, the state of the blood vessels, which move platelets. More detail in the analysis of blood is necessary to pay attention to such indexes.
MPV
MPV (Latin - mean platelet volume) - determines the mean platelet volume and their age. The normal is - 7-10 femtolitrov, the English abbreviation - fl and fL. The people of retirement age norm may differ upward - 10-12 fl. This indicator is important because it allows you to select the young cells and in the future to make a prediction about the functioning of the blood clotting process. Among the fl it becomes clear whether there is a threat of bleeding or pathologies of various organs.
PCT
PCT (Latin - platelet crit) - the percentage of blood that is occupied by platelets. Using this index can determine the level of calcium metabolism, and overall health. Normally amounts - 0.5-2 ng / ml.
PDW
PDW - relative platelet distribution width by volume, The different parts of the structure, a comparison of cell size and shape. Normally it is 14-18%.
The most important and important rule - to be tested on an empty stomach (wait at least 12 hours after the last meal).
It should also be borne in mind that figures may fluctuate in the rules:
- men and women;
- if a woman is pregnant, or her menstrual cycle;
- all ages of people.
Seek professional help and not risk your health. The doctor will collect history and make the right conclusions, comparing all indicators. Timely patient access to a doctor to prevent serious consequences and does not develop disease.
