Which organism is MOST likely responsible for septic reactions associated with
Red Blood Cell transfusions?
Yersina entercolitica is most 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
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 macrophage-monocyte system.
Diseases associated with dysfunctions of polymorphonuclear neutrophils (PMNs)
Chediak-Higashi syndrome (CH), Chronic granulomatous disease (CGD),
Myeloperoxidase deficiency (MPO)
,Nephrotic Syndrome:
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. Fats are also present in the urine in most cases. A foamy
appearance of the urine is a key characteristic of this condition.
Clinical symptoms include:
Swelling
Weight gain from fluid
retention Poor appetite
High blood pressure
Key Biochemical reactions for Enterobacteriaceae:
The key biochemical reactions by which the family Enterobacteriaceae can be
identified include fermentation of carbohydrates, reduction of nitrates to
nitrites and the absence of cytochrome oxidase activity.
Prozone effect:
Results in a false positive reaction; is the result of antibody excess and dilution
of antibody can help prevent its occurrence
Purpose of a bi-chromatic analyzer with dual wavelengths is:
Minimize the effect of interference
, Key characteristics of Micrococcus:
Susceptible to bacitracin ("A") and resistant to furazolidone; gram positive
cocci in tetras, bacteria cells of micrococcus luteus are larger than those of
the staphylococci and can arrange in tetras
What is the glomerular filtration rate for a patient with a serum creatinine of 2
mg/dL, if the urine creatinine was 124 mg/dL and the urine volume was 2.2
L/24 hrs?
95 mL/min
One method of calculating a glomerular filtration rate is using creatinine and
urine volume to determine creatinine clearance. 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:
Breast cancer
The prozone effect ( when performing a screening titer) is most likely to result in:
Prozone effect (due to antibody 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.
