In the diagnosis of various diseases, an extensive blood test is of great importance. You will be sent to this procedure if symptoms are not enough to make a correct diagnosis. Do not be afraid, a blood test is the easiest way to determine exactly what condition your body is in. A general clinical blood test, deployed, or compressed, will be ready within a few hours of sampling. How to understand the received data and whether it is necessary for the patient? Let's discuss.
Why do we need a detailed clinical blood test?
The clinical analysis of a blood is and is the general developed or unwrapped analysis of a blood. With his help, the doctor will be able to track three main areas:
- hemoglobin level;
- the number of red and white blood cells (erythrocytes and leukocytes), as well as their percentage;
- leukocyte formula and erythrocyte sedimentation rate (ESR).
In addition, the results of a blood test include:
- thrombocytes;
- the level of blood coagulation, that is, the rate of its coagulation;
- hematocrit;
- color index of blood.
Analyzing the data, the expert will make his conclusion. But if you are concerned about anxiety, and you want to personally make sure that there are no errors in the diagnosis, we will tell you what the main indicators mean.
An expanded blood test - transcript
The hemogram fully illustrates the quantitative and qualitative composition of your blood. Because it uses Latin terms in abbreviated form, it will be enough to know this or that notation in order to understand what it is about.
One of the main indicators is HGB. This is the level of hemoglobin, an iron-dependent protein, which is responsible for saturation of the organs with oxygen. For men, the normal content is 14.5 g% hemoglobin in the blood, and for women - 13.0 g%.
What else shows a detailed blood test?
Here is a short list of notations and their decoding:
- WBC - the number of leukocytes;
- RBC - the number of red blood cells;
- HCT - hematocrit;
- MCV is the average volume of red blood cells in the blood;
- MCH is the mean hemoglobin in the erythrocyte and its concentration (MCHC);
- RDW-CV - the width of distribution of red blood cells;
- PLT - the number of platelets;
- PCT - thrombocrit;
- MPV is the mean number of platelets and the width of their distribution by volume (PDW);
- NEUT - neutrophilic granulocytes;
- LYMPH, MONO, EO, BASO - the number of lymphocytes, monocytes, eosinophils and basophils, respectively.
How to take a detailed blood test?
A general detailed blood test can be taken without preparation, if the case is severe, and the solution of the problem is urgent. In this case, most likely, the blood will be taken from the vein so that the laboratory can work quickly and not save materials. If you have the opportunity to prepare for the analysis, use the recommendations of doctors, this will help to obtain the most objective data:
- On the eve of a trip to the laboratory, you should completely eliminate the use of alcohol and coffee. For dinner, eat the usual dish for you in an amount sufficient to not be hungry, refusing breakfast the next day. However, do not particularly lean on spicy, salty and fatty foods. It is not advisable to eat exotic fruits, chocolate and a large amount of sweet.
In the morning do not forget that you need to pass the test on an empty stomach. In order not to experience weakness, you can drink a cup of weak unsweetened tea and eat one small bread crumb of bread. But it's better if you manage without it.
The planned detailed analysis of the blood passes as follows: capillary blood from an anonymous finger is taken with the help of sterile needles (scarifiers) and pipettes. These tools are one-off and will be used for you individually. If you need a biochemical blood test - you will have to sacrifice a little venous blood for the study. For routine clinical analysis, this is usually not required.
