From where is d blood taken for diagnostics in humans?

Answers:
In adults, phlebotomists usually draw blood from the antecubital vein. That vessel is located on the inside of the elbow. Some tests can be done with no more than a drop of blood, in which case a lancet can be used to make a small puncture of the finger tip or heal.

Usually a blood sample is taken from the vein in the arm on the inside of the elbow. I think it might be the cephalic vein.

There are two main sources of blood for lab testing--veins and arteries. Veins are the most common source of blood. Arteries are usually only targeted to get an ABG (Arterial Blood Gas) reading.Also, finger sticks are often used to collect very small samples of blood to check a person's blood glucose levels.Hope this helps!

Blood is normally taken from the veins for most kind of diagnosis. But, blood is also taken from the arteries on rare occasions when one probably needs to test the oxygen levels in blood, before it reaches the tissues. Also fingure pricks for tests like blood group test, blood count, hb%, and now-a-days even glucose.

For the routine blood investigations like complete blood count(which shows ur hemoglobin level, total white blood cell count, platelets n etc), liver function test, renal function test, blood grouping and cross matching they use the venous blood. But for tests like arterial blood gases they use the arterial blood.
