Kidney transplant recipient's perceptions of blood testing through microsampling and venepuncture

A survey of kidney transplant recipients receiving two innovative microsampling methods, dried blood spot and volumetric absorptive microsampling using patient reported methodology. A total of 39 adult transplant patients underwent venepuncture and finger prick-based blood draws on two occasions. They completed a survey of blood test understanding, tolerability, preferences and the burden associated with venepuncture compared with microsampling. A total of 85% of participants (n = 33) preferred finger prick-based sampling and 95% (n = 37) were interested in blood collection using self sampling by finger prick at home; 33% (n = 13) of participants experienced blood test anxiety. To quantify time burden of providing venous samples a total of 44% (n = 17) spent greater than 1 hour to travel and provide venous samples. This study observed a patient preference for microsampling for blood sampling as an alternative to venepuncture in the management of their kidney transplant.
