2nd Credit Test - Deck 1 Flashcards
(15 cards)
Functional test for determination of compliment activity employ the ability of activated compliment to:
Lyse sensitized erythrocytes.
Glacial acetic acid in Türk solution causes:
Lysis of erythrocytes and platelets.
Phagocytic activity is expressed as:
% of phagocytic cells in blood samples.
During the procedure of separation of all leukocytes from whole blood by the help of hypotonic solution, the concentration of hypertonic solution has to be:
2,7 %
In radial haemolysis test for a statement of concentration of compliment in serum the diameter of haemolysis is directly proportional:
To the concentration of compliment in patient serum.
Side scatter in flow cytometer detects:
Granularity inside of cells.
For cheking of viability of cells can be used:
Trypan blue solution.
By the help of separating solution we are able to isolate:
Mononuclear leukocytes.
The common characteristic of separating solution for isolation of mononuclear cells is:
Density (1.077 g/cm³).
The index of metabolic burst (IMB) in INT test is:
A number, which is obtained after the division of absorbance of stimulated cells by absorbance of non-stimulated cells.
The fluorescence is:
Emitting of light with a longer wavelength than light absorbed by fluorophore.
In the test for respiratory burst activity in phagocytes tetrazolium is:
Reduced into a purple formazan.
To evaluate ingestion by flow cytometry , we can use a suspension of … E.coli.
FITC-labelled.
Fluorochrome used in IFA test:
Emit visible light of different colour after the exposition to UV light.
Complement fixation test (CFT) is used for:
Determination of antibody concentration in patient serum.
