Abstract :
Anticoagulants are substances that prevent blood clots by binding or
precipitating calcium or by inhibiting the formation of thrombin needed to convert
fibrinogen to fibrin in the clotting process. The K2EDTA vacuum tube
recommended by the International Council for Standardization in Hematology
(ICSH) and the Clinical and Laboratory Standart Institute (CLSI). Comparison of
blood with inappropriate anticoagulants can give inaccurate results on the number
of erythrocytes.In examinations in clinics and hospitals, improper filling of
vacuum tubes still often occurs because there are not many hospitals or clinics in
providing microtubes for the blood collection of infants and children. Less
anticoagulants will cause high hypertonicity, causing fluid contained in cells will
come out to maintain osmotic pressure. So that its use in concentration must be
precise and must be considered.
This research literature study uses descriptive analysis methods sourced
from books and scientific journals in the last 10 years. Based on the review that
has been done, the examination was carried out using the K2EDTA vacuum tube
with a difference in volume using an automatic device.
The results of research by Xu M, et al with a value of R2 0.994, research
by Gupta, et al with an F value of 0.006 and research by Dayalan, et al with a P
value of 0.9884. In conclusion, there was no significant effect on the difference in
the volume of blood in the K2EDTA tube vacuum on the number of erythrocytes.
After the analysis, it was concluded that the difference in blood volume in the
K2EDTA tube vacuum did not significantly affect the number of erythrocytes
