Abstract:
This is descriptivecross sectionalstudy carried out in the Khartoum teaching
hospital research and laboratory unit to determine the Prothrombin time and
International normalized ratio.
The Prothrombin time and International normalized ratio was measured
in100 blood samples.4.5ml of venous blood was drown from each patients
placed in tri sodium citrate containers then centrifugated to get platelet poor
plasma.
PT measured by the manual method and semi automated method
(DiagnosticaStago).
The aim of this study to compare the reliability of prothrombin test using
manual and semi-automated method coagulation analyzer.
Results were analyzed by Statistical package for social science average ±SD
and P.value was obtained.
It has been found that there was no significant variation between PT and
INR values when using the manual and semi automated with P.value
(≥0.05).
The result for the prothrombin time test obtained by semi automated is
reliable and is statistically equivilant to those obtained by the manual
method.
The study concluded that there weretwo methods gave the same results
indicating good calibrated machine.
