How to draw blood from veins by vacuum tube

Objective assessment of patient status based on laboratory data, gives more accurate results than subjective data obtained from the patient. The results of laboratory tests allow not only timely and accurate diagnosis, but also to assess the quality of the therapy. That's why medical staff need to ensure a high degree of reliability of the results.

The degree of credibility can be affected by several factors:

• pre-prepare a person for blood sampling;
• the time of day, which was held to take the material for laboratory tests;
• tools used for sampling and a technique of obtaining material;
• adherence to the algorithm of sampling.

• to completely eliminate the contact between medical staff during the collection of material with the patient's blood;
• to standardize the process of blood sampling and sample preparation, to create a simple sequence of actions;
• to reduce the number of operations spent on sample preparation to study in the laboratory;
• primary tubes that are included in the systems with negative pressure, can be used directly in many automated analyzers. This saves money on the purchase of recycled plastic tubes and the time to transfer them samples;
• to make transport and centrifugation of biomaterial more secure because the tube is sealed, made of unbreakable material;
• to facilitate the identification and labeling of samples according to types of research by color coding the caps system with negative pressure;
• to reduce material costs of the laboratory for the purchase and handling of the additional secondary tubes;
• to simplify the technique of training of the personnel;
• to reduce occupational risk of infection;
• to reduce the time spent on taking venous blood by way of the article.

At the preparation stage in the process of taking of biological material from the vein, the medical personnel should:

1. To handle arms, using the scheme provided by the who.
2. When working with blood, everyone is treated as a potential carrier of blood-contact infection. Therefore, before beginning the procedure of blood sampling is necessary to change into protective clothing.
3. To register in the register on the direction of the blood. This is necessary for marking the instruments and filling of documents related to one person. In the direction you specify passport data of the patient, date and time of blood sampling, the registration data analysis in the lab, the doctor who ordered the analysis.
4. Compare the information in the direction data of the particular patient.
5. To check whether the patient informed consent forthe procedure in detail to explain the purpose and consistency of its implementation.
6. To clarify compliance with the rules sick of the limitations in food taken before testing.
7. It is convenient to arrange the patient.
8. To prepare the workplace: arrange all the supplies needed for taking blood, pre-convinced of the integrity and fitness for purpose (the preservation of seals, sterility, shelf life, etc.). Choose a tube with desired color-coded the required amount. Take an appropriate sized needle.
9. Wear a mask, goggles, rubber gloves.
