This type is associated with either the presence of both erythroid and myeloid precursors OR strictly erythroid precursors. Myelomonocytic leukemia - ANSWER - Is associated with an increase in myeloid and monocytic cell precursors, but not red blood cell precursors Species that are Lysine (+), arginine (=) and ornithine (+): - ANSWER - Enterobacter aerogenes, Edwardsiella species and most Serratia species Lysine reaction for all Citrobacter: - ANSWER - Negative Key identifying characteristic for Pantoa (Enterobacter) agglomerans : - ANSWER - negative reactions for the three decarboxylases commonly tested ( Lysine, arginine and ornithine) Which organism is MOST likely responsible for septic reactions associated with Red Blood Cell transfusions? - ANSWER - Yersina entercolitica is mo st likely responsible for septic reactions in transfusions of Red Blood Cells. This organism is usually acquired by ingestion of contaminated food and causes mild symptoms of abdominal pain and diarrhea. Growth of Y. entercolitica is enhanced in iron -rich environments such as red cell components. Gaucher's disease - ANSWER - The most common lysosomal storage disease caused by insufficient activity of the lysosomal enzyme glucocerebrosidase that leads to the deposition of glucocerebroside in cells of the mac rophage -monocyte system. Diseases associated with dysfunctions of polymorphonuclear neutrophils (PMNs) - ANSWER - Chediak -Higashi syndrome (CH), Chronic granulomatous disease (CGD), Myeloperoxidase deficiency (MPO) Nephrotic Syndrome: - ANSWER - Caused by damage to the kidneys, especially the basement membrane of the glomerulus; which causes abnormal excretion of protein and red blood cells in the urine.

The equation is as follows: Creatinine Clearance = (urine creatinine X urine flow rate) / plasma creatinine; where urine flow rate = volume in mL /24 hours x h/60 min) In this case = creatinine clearance = 124 X (2200/24 x hour/60) / 2 = 94.7 or 95 ml/min Estrogen and progesterone markers are most commonly used to provide prognostic information about: - ANSWER - Breast cancer The prozone effect ( when performing a screening titer) is most likely to result in: - ANSWER - Prozone effect (due to anti body excess) will result in an initial false negative in spite of the large amount of antibody in the serum, followed by a positive result as the specimen is diluted.
