Background: Thalassemia and hemoglobinopathies are inherited red blood cell disorders found
worldwide. Hemoglobin (Hb) E disorder is one of the hemoglobinopathies known to have the high
prevalence in South East Asia. Most of transfusion-dependent thalassemias were genotypically
compound heterozygous Hb E/ β-thalassemia. In Malaysia, the national screening program for
thalassemia was implemented for early pregnancy or secondary school girls; however many participants
do not turn-up and missed the screening test. Screening for thalassemia using samples from cord
blood is an alternative choice as it is a readily available source of blood and hence early detection
of the disease. The purpose of this study was to determine the potential use of cord blood for the
screening of HbE hemoglobinopathy by using capillary electrophoresis (CE). Methods: Cord blood
samples were collected from 300 newborns of healthy mothers. Hematological parameters were
determined and hemoglobin quantitation for all cord blood samples were performed using capillary
electrophoresis system (CES) and high performance liquid chromatography (HPLC). Results: Majority
of cord blood samples (63%) revealed Hb AF followed by Hb AFA2
(20%). Hb AFE was detected
in 10.7% with the mean value of Hb E ranging from 2.3%-11.1%. Conclusion: Hemoglobin E was
detected in cord blood using capillary electrophoresis system. It can be recommended in areas where
Hb E/β is prevalent. Implementation of a screening strategy using CE on cord blood sampling will
identify the disease early. With regular follow-up on these patients, the status of their disease can
be determined earlier and appropriate management implemented.

Background: Unsafe blood products may cause transfusion-transmissible infections. This
study aimed to evaluate the knowledge and perceptions of blood donors regarding blood safety.
Methods: This was a cross-sectional study conducted in the Kelantan state of Malaysia.
The questionnaire comprised 39 questions that covered areas such as donors’ social demographic
information, knowledge of transfusion-transmitted diseases, blood screening and donor eligibility
and perceptions towards blood safety. The knowledge score was categorised as good or poor.
Results: Of the 450 distributed questionnaires, 389 were suitable for analysis. Only
18.5% of the donors had good knowledge, with 81.5% having poor knowledge. Less than 30% were
aware that people with multiple sexual partners, bisexual people and male homosexual people
are permanently deferred from blood donation. Only 29.4% agreed that donors are responsible if
their blood causes infection. Furthermore, 39.3% assumed that they could check their HIV status
through blood donation, and 10.3% and 5.4% of the respondents believed that donors are free from
infection if they wear a condom during sex or only have oral sex when involved in prostitution,
respectively.
Conclusion: Poor knowledge and notable misperceptions concerning safe blood donation
were found among blood donors. The Ministry of Health should incorporate safe blood education
in future public awareness programmes.

Introduction: Unsafe blood products cause transfusion-transmissible infections. A good knowledge and perception about blood safety issues is crucial to ensure safe blood supply. The objective is to develop and validate a questionnaire about the knowledge and perception among blood donors on blood safety issues. Method: A cross-sectional study was conducted among 130 blood donors who attended the National Blood Centre, Kuala Lumpur in April and May 2018. The questionnaire was developed in the Malay language after extensive literature search. The self-administrated questionnaire consisted 39 items which required around 20 minutes to complete. The validation involved content validity, construct validity using exploratory factor analysis and reliability using test-retest analysis in IBM SPSS statistics. The same group of respondents was retested after two weeks using the same questionnaire. Results: Content validity was established through multidisciplinary expert meeting and two content reviewers. The factors loadings of all questionnaires were more than 0.40. Knowledge questions were divided into three domains; perception questions were divided into four domains. The intraclass correlation (ICC) values of the test-retest were more than 0.80 for the three knowledge domains and more than 0.60 for the four perception domains. The third domain of the perception section which consisted two questions had the lowest ICC value of 0.686 (95% CI 0.583-0.767). One of the questions was restructured to improve clarity. Conclusions: The questionnaire on knowledge and perception on blood safety issues has good validity and reliability, with appropriate items which warranted its utilization among blood donors.
