what the risks are pk, pyruvate kinase, blood test to detect abnormally low levels of pyruvate kinase, pk, an enzyme that helps convert glucose to energy, oxygen is low, termed anaerobic metabolism, pk is found in red blood cells, pk is deficient, red blood cells break down more rapidly than usual, destruction, result in hemolytic anemia, too few oxygen-carrying red blood cells, blood is drawn, a vein, on the inside, the elbow, the hand, puncture site is cleaned, antiseptic, an elastic band, around the upper arm to apply pressure, restrict blood flow, the vein, veins below the band to fill, blood, a needle is inserted, vein, blood is collected in an air-tight vial, a syringe, band is removed, restore circulation, once the blood has been collected, needle is removed, puncture site is covered to stop any bleeding, white blood cells, removed, test results, level of pyruvate kinase is analyzed, , child, have this test performed, to explain how the test, demonstrate on a doll, explain the reason, knowing the "how, why", reduce the anxiety child feels, the needle is inserted to draw blood, feel moderate pain, a prick, stinging sensation, some throbbing, hemolytic anemia has many causes, present from birth, acquired, a deficiency in pyruvate kinase is fairly rare, test helps health care provider determine the cause of anemia pyruvate kinase level is measured in relation, hemoglobin, a normal part of red blood cells, sample, results vary depending upon the testing method used, laboratory performing the test, consulted, the range of values seen in healthy individuals, low levels of pyruvate kinase confirm pyruvate kinase deficiency, distinguish between anemia, pyruvate kinase deficiency, inherited disorders, risks associated, having blood drawn, slight, excessive bleeding, fainting, feeling light-headed, hematoma, blood accumulating under the skin, infection, a slight risk, the skin is broken, multiple punctures to locate veins, veins, arteries vary in size, obtaining a blood sample.
