5.5.2022 Flashcards
Nucleated platelets (thrombocytes) are not present in the blood films of:
mammals
Total blood volume in fish is:
1-2%
The diagnostic importance of MCV is:
It provides information about red blood cell size and is expressed in fl
Typical haematological findings in haemangiosarcoma are:
acanthocytes, schistocytes, reticulocytosis, transient hypoproteinemia, thrombocytopenia
Plasmin is needed for:
cleavage of fibrin, resulting in breakup of the clot and creating fibrin degradation products (FDPs)
Mixture of blood and lymph in blood collection occurs in:
reptiles
True or false:
The labs report the presence of haemolysis, lipaemia and icterus with the results and usually state whether is mild, moderate or severe or donate this in terms of 1+ to 4+:
True
Interprete following lab findings: normal packed cell volume with low plasma protein:
hypoproteinemia (usually hypoalbuminemia) due to failure of production or protein loss
Chronic leukemia occurs:
when the neoplastic transformation occurs in either a stem cells or later cell but progeny retain a strong tendency to differentiate, the cells are morpholgically well differentiated but are functionally abnormal
What is reference interval?
Interval between upper and lower limit and commonly includes 95% of the apparently healthy ‘‘normal’’ reference population by statistical methods
True or false:
Erythropoietin is low or low normal in primary erythrocytosis
True
The longest life span of red blood cells is in:
reptiles
What are Heinz bodies and what is their diagnostic importance?
RBC with small eccentric pale structures, they protrude from red blood cell margin and represent haemoglobin denaturation; oxidative injury
Prostacyclin (prostaglandin PGI2) is needed for:
Inhibition of expression of fibrinogen receptors on the platelet and the secretion of dense granule constituents
What is hypochromatic cell:
It is the cell that is pale and has increased cellular palor
