HASH BROWNS

HASH BROWNS COMPLETE BLOOD COUNT 431. SCREENING PROCEDURE that is helpful in the diagnosis of many diseases, it is one indicator of the body's ability to fight disease, it is used to MONITOR the effects of drug and radiation therapy, and it may be employed as an INDICATOR OF PATIENT'S PROGRESS in certain diseased states such as infection or anemia. HEMATOCRIT 432. TRAPPED PLASMA: amount of plasma that still remains in RBC portion after the microhematocrit has been spun. Increased in macrocytic anemias, spherocytosis, thalassemia, hypochromic anemia and sickle cell anemia 433. When comparing spun hematocrit results obtained on an electronic cell counter, the spun hematocrit results vary from 1 to 3% HIGHER because of this trapped plasma (unless cell counter has been calibrated). 434. Anticoagulated blood should be centrifuged within 6 hours of collection when the blood is stored at room temperature. 435. Overanticoagulation: FALSELY LOW due to shrinkage of cells 436. Air bubbles denote poor technique but do not affect the results 437. Incomplete sealing of the microhematocrit tubes: FALSELY LOW 438. Inadequate centrifugation of the microhematocrit tubes or allowing the tubes to stand longer than several minutes after centrifugation: FALSELY ELEVATED 439. Hematocrit may be expressed in either of two ways (1) as percentage, e.g., 42% or (2) as a decimal point, e.g., 0.42. WHITE BLOOD CELLS COUNT 440. Count above 11 x 10 9th/L is termed LEUKOCYTOSIS 441.

In anemia, the hemolysis may be slightly increased in PNH negative specimens 454. Use of defibrinated blood may cause positive results due to the hemolysis of traumatized RBCs 455.

PNH: 10% to 80% hemolysis ACID SERUM TEST 459. Whole blood defibrinated 460. When patient has received blood transfusions, less lysis occurs because of the presence of normal transfused red blood cells
