Objective: In clinical laboratories, the tests of prothrombin time (PT), and partial thromboplastin time (aPTT) are generally analysed fastly after blood collection. In addition to this, sometimes the blood samples can be kept as frozen in order to be analysed at a later...

Purpose: The maturation of hemostatic system continues from fetal life to adult. Determination of agedependent reference ranges for coagulation is therefore very important to evaluate correctly the hemostasis. The study aimed to establish age-dependent reference range for...

Aim: In this study, it was aimed to examine the changes of activated partial thromboplastin time (APTT), prothrombin time (PT), and plasma fibrinogen during the day, which are the most used coagulation tests in daily routine.

Material and Methods: Blood...

Objective: If a new analyzer in the laboratories is considered to be used, method comparison should be done. Two analyzers should be compared in order to evaluate accuracy of the new analyzer. In our study, we aimed to compare the performance of new coagulation analyzer with...

Purpose: The aim of this study is to determine the activated partial thromboplastin time (aPTT), prothrombin time (PT), international normalized ratio (INR) reference values to be used in our hospital population.

Materials and methods: In this study,...

Aim: This study aimed to evaluate the performance characteristics of preliminary coagulation tests on the Sysmex CS-5100 coagulation autoanalyzer and compare it with the ACL Top 700 autoanalyzer. Both analyzers were assessed for their ability to measure prothrombin time (PT),...

Aim: Point Of Care (POC) tests are quick tests that shorten the treatment period and are portable devices, which are easy to use for non-laboratory personnel. In this study we aimed to compare the results of INR (International Normalized Ratio) that were studied with POC...

Objective: It's important to determine reliable reference intervals for all the test parameters of the clinical laboratory, but it's usually hard to obtain useful and necessary clinical data. Although the procedure of indirect determination of reference intervals using...

Objective: The laboratory critical values are the laboratory testing results which required attention or action by the physicians. The aim of this study is to investigate the laboratory critical value notification process in our laboratory in terms of patient safety and...

Hemophilia A and B are X-linked bleeding disorders characterized by the absence or reduced activity of coagulation caused by mutations in the factor VIII and factor IX genes, respectively. Diagnosis of hemophilia is based on understanding the clinical features and symptoms of hemophilia,...

Aim: Hereditary thrombophilia is a condition where there is an increased tendency for clot formation due to a genetic variation in the coagulation system. Genetic testing in cases with a preliminary diagnosis of thrombophilia is necessary to confirm the diagnosis, eliminate...
