The Correlation Between Patient Age and Coombs Test Result at The Blood Donor Unit of The Indonesian Red Cross Surakarta City

Abstract

Blood transfusion is an important medical treatment used for managing different blood-related diseases, especially in people with cancer that affects the blood. One key test used before giving a blood transfusion is the Coombs test. Research shows that Autoimmune Hemolytic Anemia (AIHA) is more common in people who are 40 years old or older, and getting a positive result on the Coombs test is also more likely in this age group. The goal of this study was to find out how a person's age is connected to their Coombs test results at the Blood Donor Unit of the Indonesian Red Cross in Surakarta City. This study is a type of observational research that looks at data collected all at once.It was used to see how patient age (the independent variable) relates to Coombs test results (the dependent variable) without any changes made by the researchers. A total of 83 respondents were included as the sample.. The data came from secondary sources, specifically from the Coombs test results that were recorded in a log book at the Blood Donor Unit. The study used the Eta correlation test, which is used to check how two types of data are related.The Eta values found were 0.213 and 0.347. Since these numbers are close to zero, the link between age and Coombs test results is considered weak. There is a slight connection between a patient's age and their Coombs test results, but the connection is very weak.
