Abstract

Pre-transfusion testing is a mandatory procedure to ensure compatibility between donor and recipient blood; therefore, the selection of sample type is a critical factor in determining the accuracy of test results. The use of blood samples with anticoagulant EDTA or without anticoagulant (serum) is suspected to influence crossmatching outcomes. This study aimed to analyze the effect of sample type on crossmatching results at the Blood Transfusion Unit of PMI Nunukan Regency. A pre-experimental study with a static group comparison design was conducted on 30 patient samples using a total sampling technique. Crossmatching examinations were performed using the gel test method and analyzed with the McNemar test. The results showed that all EDTA samples (100%) were incompatible, while serum samples showed 30% compatible and 70% incompatible results. Statistical analysis indicated a significant difference (p=0.000). It is concluded that the use of serum without anticoagulant is more recommended as it reduces false-positive reactivity and improves the efficiency of blood transfusion services.

Abstract

Maintenance of hemoglobin (Hb) levels in blood is an essential requirement for regular donors to ensure donor eligibility and recipient safety. Observations at UDD PMI West Lombok indicated a high rate of donor disqualification due to low Hb levels. This study aimed to analyze the relationship between jogging activity and Hb levels among regular donors at UDD PMI West Lombok Regency. An analytical observational study with a cross-sectional design was conducted on 91 respondents selected using the Slovin formula. Physical activity data were collected through a Guttman scale questionnaire, while Hb levels were measured using the Hemo Control device. Data were analyzed using the Chi-Square test. The majority of respondents were male (73%), with the dominant age group being 40–49 years (42%). A total of 53% of respondents regularly performed jogging, and 62% had Hb levels within acceptable specifications. The Chi-Square test showed a p-value of 0.001 (<0.05). There was a significant relationship between jogging activity and hemoglobin levels among regular donors.
