Patient Self-Testing of Kidney Function at Home, a Prospective Clinical Feasibility Study in Kidney Transplant Recipients
Murray et al.
The finding, in our words
In kidney transplant recipients, home capillary blood self-testing of creatinine using a handheld analyser showed good agreement with clinic venous laboratory results, whereas potassium showed poorer agreement; patient self-use of the device was not a significant source of the potassium difference.

This UK consensus opinion outlines how clinical laboratories can validate self-collected capillary blood sampling against venous reference standards to achieve accreditation and facilitate the shift towards community-based patient care.

Capillary blood samples collected by staff or self-collected by participants showed strong correlation and clinically acceptable agreement with venipuncture for influenza haemagglutination inhibition titers. The small differences observed were not clinically meaningful, and adequate sample volume was achieved in most attempts, supporting the feasibility of decentralised serological testing.

This study found strong concordance between capillary samples collected via the Tasso device and standard venous draws for VirScan serology, indicating that self-collected samples are a practical alternative for decentralised research. The authors advise against interchanging these collection methods within a single longitudinal study to avoid introducing technical variability.
Self-collected capillary blood samples posted by standard mail showed high concordance with couriered venous samples for HbA1c, creatinine and lipid parameters, supporting their use for remote monitoring in diabetes management and screening.

Although most kidney transplant recipients successfully collected capillary blood samples at home, haemolysis and transport conditions affected analyte stability. Agreement with venous sampling was acceptable for haemoglobin and creatinine, but potassium and haematocrit exceeded total allowable error limits.
