Abstract
Between April and May 2022, 10 healthy adult non-patients were recruited from Pusan National University Hospital. Venous blood drawn into a syringe was transferred into test tubes with a zero-to-45-minute delay. The transfer was done sequentially in two positions with the syringe and the needle adaptor end (1) heading downwards and (2) heading upwards. Haemoglobin levels gradually increased over time in position 1 transfer while they gradually decreased in position 2. Therefore, blood must be transferred quickly from a syringe to a tube for reliable test results.
What this study adds: Our findings confirm that delays between blood collection and transfer can affect haemoglobin levels.
期刊介绍：
The African Journal of Laboratory Medicine, the official journal of ASLM, focuses on the role of the laboratory and its professionals in the clinical and public healthcare sectors,and is specifically based on an African frame of reference. Emphasis is on all aspects that promote and contribute to the laboratory medicine practices of Africa. This includes, amongst others: laboratories, biomedical scientists and clinicians, medical community, public health officials and policy makers, laboratory systems and policies (translation of laboratory knowledge, practices and technologies in clinical care), interfaces of laboratory with medical science, laboratory-based epidemiology, laboratory investigations, evidence-based effectiveness in real world (actual) settings.
