  2. Iatrogenic anemia - Wikipedia

    en.wikipedia.org/wiki/Iatrogenic_anemia

    The volume of blood needed for most laboratory tests is lower than the amount that is commonly drawn; a 2008 study found that only 9% of the blood in standard sized blood tubes was used for testing. Using smaller tubes for blood tests can decrease the risk of anemia, but it may increase the risk of laboratory errors. [3]

  3. Reference ranges for blood tests - Wikipedia

    en.wikipedia.org/wiki/Reference_ranges_for_blood...

    Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

  4. Blood test - Wikipedia

    en.wikipedia.org/wiki/Blood_test

    A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .

  5. Venous stasis - Wikipedia

    en.wikipedia.org/wiki/Venous_stasis

    Weakened Venous valves: these are crucial towards ensuring upward flow to the heart from the lower extremities. If weakened, they may fail to close properly which leads to backwards blood flow/blood pooling. This can lead to slower blood flow in the veins. [8] Ultrasonography-Doppler ultrasound

  6. Phlebotomy - Wikipedia

    en.wikipedia.org/wiki/Phlebotomy

    A phlebotomy draw station is a place where blood is drawn from patients for laboratory testing, transfusions, donations, or research purposes. The blood is typically drawn via venipuncture or a finger stick by a healthcare professional such as a phlebotomist , nurse , or medical assistant . [ 21 ]

  7. Blood squirt - Wikipedia

    en.wikipedia.org/wiki/Blood_squirt

    Blood squirt (blood spurt, blood spray, blood gush, or blood jet) is a projectile expulsion of blood when an artery is ruptured. Blood pressure causes the blood to bleed out at a rapid, intermittent rate in a spray or jet , coinciding with the pulse , rather than the slower, but steady flow of venous bleeding.

  8. Hemodynamics - Wikipedia

    en.wikipedia.org/wiki/Hemodynamics

    The rate of mean blood flow depends on both blood pressure and the resistance to flow presented by the blood vessels. Mean blood pressure decreases as the circulating blood moves away from the heart through arteries and capillaries due to viscous losses of energy. Mean blood pressure drops over the whole circulation, although most of the fall ...

  9. Hypochromic anemia - Wikipedia

    en.wikipedia.org/wiki/Hypochromic_anemia

    A blood smear showing hypochromic (and microcytic) anemia. Note the increased central pallor of the red blood cells. Hypochromic anemia is a generic term for any type of anemia in which the red blood cells are paler than normal. (Hypo- refers to less, and chromic means colour.) A normal red blood cell has a biconcave disk shape and will have an ...
