What is the PDW and its importance for the body
PDW in a blood test - this designation distribution of blood cells in the bloodstream. Such blood tests needed to determine the presence of certain pathogenic processes in humans. Platelets are inherently heterogeneous, there are both small and large cells. There are several similar value - RDW, but it refers to the volume of red blood cells in the bloodstream.
Platelets - is an important part of human blood. When a blood vessel is damaged, they accumulate at the site of damage and thereby stop bleeding.
If they would be a little man in danger of losing large amounts of blood. If the platelet count is more than the other way around, it can cause the formation of blood clots that broke away, can block the vessel. This is dangerous, because the total overlap of blood flow causes the death of tissue, and in some cases death.
Therefore index PDW is very important - it determines what the platelets in the blood - high or low. If the results significantly deviate from the norm, along with others, not enough good analyzes, it may indicate a serious illness.
As conditions under which formed
PDW stands for "platelet volume distribution of blood." These are the smallest blood cells, their value is not more than 3-5 mm. The cells themselves are flat and oval in shape, they are transparent and non-nuclear.
In platelet has a purpose:
- producing reaction, in which the formed thrombus is capable to stop bleeding in the areas of tissue damage (internal and external);
- promote growth and restoration of blood vessels provide nutrition bioactive substances;
- eliminate inflammation delivered together with immune complexes;
- blood purification (filtration) of the antigens.
Platelets are formed in the bone marrow. Most of them are located in the blood vessels, less - in the spleen. In this body (as well as in liver) recycling dead cells occurs, colorless. Life of platelets - 8-11 days. In this case, the synthesis of new cells occurs without interruption. In the blood at the same time can be both young and old.
Total red blood cells in several life stages:
- youth;
- maturity;
- old age;
- irritability;
- degeneracy.
Matter at what stage of platelet depends on its size - the older, the less. The heterogeneity in terms of cells are also determined PDW (heterogeneity). If the rest of the blood cells circulating in their usual volume, slight deviations from the norm does not mean a pathology. PDW analysis is performed immediately with MPV - average volume of red blood cells.
Table PDW-norm
The PDW - Blood analysis - it is a value that has as its deviation and normal.
| A patient | Norma PDW | Features |
| men | 15-17% | |
| Women | 15-17% | During menstruation, blood test does not give up. PDW in this period is reduced (each woman differently). During pregnancy, the values also change - from the norm by 10-20%. |
| Children | 10-14% | During the growth and restructuring of the body values can be changed, but only slightly. |
The predominance of old and new platelets should not be higher than 10%, otherwise the risk of clot formation. While the reduction levels can cause a large loss of blood.
Symptoms of high and low PDW
Symptoms improve or PDW low blood depends on the disease, as a result of which the index has deviated from the norm. This can occur for various reasons, disease, because of which may decrease or increase The PDW, quite a lot.
For example, the increase of the index may indicate the presence of anemia in humans. In this case, it will be expressed in skin paleness, low blood pressure, weakness, enlarged spleen.
Reduction can also mean different reasons, including lack of vitamin B12 and folic acid. Deficiency of these elements are expressed in the nervous system problems, a strong hair loss, prone to depression.
The reasons for increases and decreases
PDW in a blood test - it is, figuratively speaking, a means of detecting the presence of dangerous diseases. Of course, you can not rely only on the value of this indicator, however, if the figure is strongly rejected from the norm, you should think about other assays and a complete inspection in general.
PDW reasons for the increase are the following reasons:
- cancer (they pretty much changed the composition of the blood in general);
- other inflammation;
- anemia;
- bleeding after surgery opened.
It is not always increasing rates means that there are serious problems. Sometimes the cause can become an elementary failure to follow before you get tested. Also, the value may deviate from normal due to reception of drugs, which anyway affect the composition of the blood.
Reduced PDW means small number of cells in the bloodstream.
Divergence from normal may be caused by the following reasons:
- lack of vitamin B12 and vitamin B9;
- dysfunction of liver and blood-forming organs;
- oncology;
- different viruses and infectious diseases;
- receiving such drugs as cytostatics, and others.
Women are not encouraged to be tested during the month, as all the evidence, in principle, be different from the norm, and platelet volume will be lowered.
However, if the reason for the low PDW is not defined, should not be neglected deviations from normal values. Reduced volume may adversely affect the organs, affecting their integrity.
Changes in PDW may occur as a result of malnutrition, bad habits, physiological characteristics of the particular organism.
Indications for study
on blood donation aimed at analyzing issues a therapist. After the inspection, he concludes, whether the person should be concerned about your health or not. Analysis and follow-up examinations or confirm fears or refuted.
The patient is sent to a laboratory where blood sampling is done and carried out a study of the resulting material. It takes time. Then all indicators, including The PDW, are issued. With the results of laboratory studies the person returns to the therapist, and he considers the result.
Issued by the laboratory results may look like a table, in which the written data (rate and the presence of the patient). can also be specifically stated whether a person deviations.
How to determine the PDW
PDW in a blood test - is a value that can change not only as a result of human pathologies, but also because of a lack of good preparation for conducting the analysis. The amount and distribution of platelets determined by the deposit of blood from a finger. To get a more detailed analysis, made a fence out of the vein.
In order for the result to be accurate, the patient should be prepared in advance:
- for 1 h. to surrender not engage in physical activity (red blood cells can result in the rise);
- meal - not less than 8 hours. ago, the blood is best to take on an empty stomach;
- 1 day it is not necessary to eat fatty, salty or spicy;
- Liquid is accepted only in the form of water;
- if possible, the day before the date it is not necessary to take medication.
If medication is required, it will need to be discussed with the doctor, and in the subsequent analyzes will take into account the availability of medicinal substances in the body.
A good time for a blood test is considered to be the morning (before eating). Before the procedure, the patient must sit for a few minutes (10-15) to align the pulse and calm.
This is important as some great hurry, and arrive at the lab in a rather excited state. After putting her blood immediately sent to study. The results can come within 1-3 days, depending on the clinic.
Doctor interprets the results. It defines normal PDW or not, on the table, and if there is any deviation, it is fixed. Only one platelet volume can not be said about the diagnosis - it is necessary to consider the rest of the blood and other tests.
Deciphering the analysis results
Deciphering PDW assumes such designations, as the norm, elevated and lowered.
The norm is the case when old and young cells are found in the blood stream in an almost identical values.
The increase in the index - this increase in the content of the young and old platelets in the blood stream, and indicates the presence of some problems in the body. Sometimes the increase in PDW and the absence of any symptoms suggests the possible presence of genetic diseases. To test this, conduct a full examination.
When the PDW is reduced, which means that in the overwhelming majority of circulation make old cells. This means that bone marrow have a problem, and the new blood cells are not produced by the same.
The analysis may also show that the presence of a person is very large platelets. Abnormally large cells represent immune system problems. Sometimes the size of the cells depends on heredity - some hereditary diseases affect the size of blood cells.
Examination of the material can give such a result - "incomplete." This means that platelets in their counting matted. To continue the research lab adds anticoagulant to split cells.
When the platelets are at odds with its norm, and the reason is not clear deviations, additional research is appointed, where already more detail will be discussed all the material for the presence of malignancies, infections and other pathologies.
At what PDW need to see a doctor
If the results of laboratory studies have shown a high or low value of the PDW - is an occasion to address to the therapist. The doctor will examine the available results, with attendant can ask questions, after which it will write out a direction for the surrender of other tests.
Do not forget that the reason for the increase can be non-compliance with rules for the procedures and taking medication. If the changes in the indices is the case, the person is sent to a second blood sample.
How to bring back to normal PDW
PDW in a blood test - this is the value at which you can not say for sure about the diagnosis. Before starting cause platelets to normal, you need to understand the reason why they have departed from the normal state. Therefore, you should first know exactly what your diagnosis. Just then the doctor prescribes the appropriate treatment - a course of medication, therapy, and other hardware.
Special attention is paid to oncological diseases. If the patient was diagnosed, the treatment involves a special treatment (chemotherapy, radiotherapy, bone marrow cells).
Before using any means a person should consult a hematologist. If you experience problems in the child, all the necessary tools for the treatment of a pediatrician will prescribe.
Medications
When the PDW in the blood dropped, the doctor may prescribe the following drugs:
- Aspirin;
- clopidogrel;
- Thrombotic ACC.
These medications can thin the blood, as in a short time, and for longer.
When it is necessary, on the contrary, reduce the rate can be assigned to such drugs:
- menadione;
- Dicynone;
- Sedokor.
If a person has gone through a procedure such as chemotherapy, normal PDW restored by receiving hormonal therapy.
should not resort to drugs without consulting a doctor - the effect of the medicines may be unexpected and cause even more problems.
Traditional methods
Traditional medicine is no substitute for full treatment, but may be an additional way to bring health in order.
Good home remedies in the recovery period after surgeries person.
One of the most popular recipes for recovery rules PDW is a ginger-honey mix recipe is very simple:
- Ginger root pounded into mush and mixed with honey in equal proportions.
- The resulting mixture was removed in the refrigerator for 3 days.
- Throughout the course (10 days) is a folk remedy to keep in the cold. You can not heat the honey and - because of this all of its nutritional properties are lost.
- Means taking as follows: 1 tbsp eat on an empty stomach. It is important to monitor the response of the body, since both of these products are potent allergens. To get started is to take 1 tsp
Even before taking people's money you need to consult a doctor as possible deterioration of allergies and other side effects. If the state has become worse, you should immediately stop taking home remedies.
Other methods
Other methods of treatment are quite a few ailments. First, the diet should be noted that a doctor can prescribe for a speedy recovery. Depending on what kind of PDW (decrease or increase), selected products.
So, with a high value should pay attention to:
- berries: blackberries, cranberries, rosehips;
- bitter chocolate;
- lemon, ginger and garlic;
- flax seed oil and seed.
At low rates in a patient can be added to food products such:
- eggs;
- red lean meat;
- sesame;
- cereals (buckwheat, rice);
- beet.
Necessarily in the patient's diet should be present vitamins B12 and C - they help restore the blood composition. Vitamins can be taken as a vitamin complexes, adding them to the diet food. Usually a course of vitamins is 30 days.
The clinics also uses hardware therapy in the form of cleansing the blood separator apparatus. This device retains blood cells, thereby reducing the PDW. Doctors give additional recommendations thanks to which after recovery can maintain normal blood counts.
They are quite simple:
- necessarily sufficient consumption amount of pure water (2 L);
- avoid physical stress for the patient will be sufficient walks and gymnastics classes;
- diet, which saturates the body with all the necessary elements and Uluchay state of the blood;
- reduce the consumption of drugs, especially if they are taken lightly.
These recommendations will help a person to maintain normal levels and to eliminate the re-emergence of pathologies.
possible complications
Ignoring the results of laboratory studies may lead to undesirable consequences. If the cause was a failure to comply with the rules before the surrender or the presence of menstruation, pregnancy, then do not worry.
However, for deviations from the norm PDW may be hiding a serious disease that should not be neglected. Without proper examination and treatment the disease will progress and eventually lead to death or disability.
The indiscriminate use of non-prescription medicines can also cause complications and worsen the situation. If assays something was not normal, it is necessary to consult a physician.
Platelet index PDW (platelet distribution width on their volume) - an important indicator in analysis of blood, and divergence from the normal value may indicate the presence of pathogenic processes body. Such analysis as blood donation, gives a clear idea of the amount of platelets, and makes it clear - whether further evaluation and treatment is necessary.
