Blood examination: All that is known

Generally, the blood test is performed when the examined arm is stretched and reversed on a flat flat or table. The investigator draws a rubber strap around the upper part of the arm, to impede blood flow as much as possible, and to limit the blood in the area from which the sample is taken with injection. Thereafter, the person subjected to the investigation is as much as possible, a movement that helps the person who examines the best blood vessel to take the monster from him. It is usually in the elbow or forearm. In some cases, the sample of the rear area of ​​the palm of the hand is taken. If a suitable vein occurs in size, the place is disinfected and sterilized with alcohol, then an accurate needle is placed. This needle is linked to a special test or injection tube. This process may not be nice and comfortable because it causes mild pain if you tingle. Later, the person investigating the investigation is needed, based on the number of test tubes (the number of test tubes required, is related to the amount and type of tests the laboratory needs to be performed). Upon completion of the blood withdrawal process, the needle is quickly removed from the vein, and then you must immediately press on the tingling place to prevent the blood flow from there and the test tubes to the laboratory for the investigation. In some cases, there is a need to make two or three attempts to tingle, when the vein cannot penetrate, or when the investigation cannot take the necessary blood for the first time. The patient should be patient, as this process is not always simple, but it takes between 5-10 minutes after the blood test can cease to squeeze the tingle place after two or three minutes, or if the bleeding stops. In most cases, very simple internal bleeding occurs in place of the investigation, and it does not require any treatment because it automatically disappears within a few days. In some rare cases, a painful painful bleeding can occur and cause swelling at the place of the examination, which requires the doctor to inform the doctor immediately to ensure that there is no pollution in the intravenous area (venous inflammation – phlebitis). Treatment may require treatment by applying hot bandages several times a day. The major risk associated with blood tests is related to the investigation by a polluted needle. Therefore, it is necessary to withhold as much as possible to perform blood tests in the Third World countries, and in other regions of the world where the rules of hygiene and sterilization are not fully emphasized.
