how to pipette
purpose: to know the number of erythrocytes cells / ul blood
principle: the blood was diluted in erythrocytes using a Thoma pipette hayem. KH then heated in the number of erythrocytes in a given volume is calculated using a conversion factor can be calculated the amount of sil erythrocytes.
way of working
A. suction of venous blood samples with anticoagulant or blood capillaries with a pipetteto mark 0.5 Thoma erythrocyte
B. remove blood attached to the outside of the pipette tip
C. and suction solution to the mark 101 hayem
D. shake the pipette so that a homogeneous, dispose of 3-4 drops
E. prepare the count room is clean and dry the glass deck on top, then put on a microscope
F. drop one drop into the room let the count 2-3 minutes
G. count the number of erythrocytes in five boxes were in the middle with a magnification of 40x
criteria
a. cells that are tangent to the line left, the calculatedb. cells that are tangent to the line right, down, do not count
purpose: to know the number of erythrocytes cells / ul blood
principle: the blood is diluted with a solution of Rees Ecker in serological tubes and then inserted into the room count the number of erythrocytes counted in a given volume using a conversion factor of the number of erythrocytes / ul of blood can be taken into account
way of working
a. insert into serological tubes 0.4 ml solution of Rees Ecker using a measuring pipette0.5 mlb. suction of venous blood samples or blood anticoagulant kapilerdengan of 20 CMMc. remove the remaining blood out of the pipette tip attached to adjacentd. input end of the Hb in vitro serological pipette wash 3-4x
e. the tubes were closed with parafilm and mixed until a homogeneousf. KH is clean and prepare the cover glass microscope mounted horizontally on a tableg. KH fill it with blood that has been diluted before pasteur pipette premisesh. allow 2-5 minutes for diving KH erythrocyte sedimenti. yag count the number of erythrocytes was found in five boxes with a 40x objective
