Blood Taking Procedure For HIV Test?
I want to ask … Why is blood drawn in a lab for HIV testing via veins. Why not on the buttocks or thighs or legs. It is the same as blood … why is it generally in the veins that are .. are all those viruses channeled to the veins in the arms
Hello Mekelichen, thank you for asking on HealthReplies.com.
Basically, blood is only present in blood vessels only, and blood vessels are broadly divided into 2 parts, namely veins and arteries where each of these blood vessels has different characteristics.
Veins are chosen for blood collection because these vessels are anatomically located on the outermost side (very close to the surface of the skin), making it easier to reach when blood is being drawn. In addition, these blood vessels flow towards the heart, so that the blood pressure in these blood vessels will not be as high as those in the arteries, so that if the stabbing is done, the blood that comes out will not radiate fast and can be stopped immediately after the stabbing is complete .
As for why the chosen location is in the arm, because in terms of anatomy too, the location is the safest and easiest location for blood collection, and also taking at that location will cause less pain than the blood collection at the location veins on other parts of the body. However, if the main location of the blood draw is no longer possible to use (for example there are wounds or injection marks), then it can be considered to use veins in other parts of the body for blood collection.
Also note that the virus will circulate in any blood vessel, not only in the vein, and will circulate throughout the body, not only circulating in the arteries of the arm. However, it should also be noted that all examinations or medical actions carried out, especially when dealing with blood vessels, are all carried out on the basis of their anatomy, function and characteristics so that for each action or examination, there are procedures and limitations on the vessels themselves. which blood the action or examination should take.
I hope this helps.
