Analysis of the KLA (complete blood count) is perhaps one of the most common clinical actions. In Russia, the ring finger of the left hand is most often used to take this analysis. This is not a violation if the correct blood sampling technique is followed. Massaging and rubbing your finger before the procedure is not recommended. These actions may affect the accuracy of the analysis. There are other techniques for the KLA. Analysis can be taken from the ulnar vein. In this case, it is better to use special tubes. The vacuum created in them contributes to the most correct procedure.
Patient preparation rules
When a UAC analysis is prescribed, the patient must be warned about some preparatory measures.
- The procedure is performed on an empty stomach. 8 hours before the analysis, you need to refuse food intake. You can not drink sweet drinks, coffee, tea, juices. You can quench your thirst with water. If KLA is taken in children of very young age, and it is difficult to analyze on an empty stomach, then it is permissible to make a fence in 1.5-2
hours after eating. - For 1-2 days, it is recommended not to drink alcohol, refrain from smoking, and also remove all fried and fatty foods from the diet.
- KLA analysis can be affected by physical stress and emotional disturbance. Therefore, 15 minutes before the procedure, you need to sit, relax and calm down.
- Before donating blood, it is recommended that you stop taking the medicine. If this is not possible, then the doctor should be warned about the drugs used. Then he will make a correction in the analysis.
The objectives of the UAC
The main goal of this analysis is to determine the quantitative indicators of the main elements of the blood. Here are some of them:
- erythrocytes - blood cells that transport oxygen to internal organs;
- hemoglobin - a component of red blood cells involved in the delivery of oxygen to organs;
- hematocrit - an indicator of the ratio of red blood cells and blood plasma;
- platelets - cells responsible for blood coagulation ;
- white blood cells - cells responsible for immune function;
- ESR - an indicator that determines the content of plasma proteins (often helps to identify inflammatory processes in the body).
Other types of blood tests
KLA analysis is not the only way to study a vital fluid. In addition to it, there are many methods with which you can examine blood from various angles. We briefly describe some of them.
Biochemical analysis
Such a study reveals enzymatic blood counts. In addition, biochemical analysis allows you to determine the amount of proteins, lipids, nitrogenous substances and vitamins. Also, with the help of it, a diagnosis of various disorders in the body is carried out. For example, malfunctions in the liver, kidneys, and urogenital system are determined.
Hormone test
It helps to identify many diseases of the endocrine system by examining the hormonal background in the body.
Allergen Analysis
Investigates the level of substances that can cause aggressive actions of the immune system and provoke the manifestation of various allergic reactions.
