Mitra v Fingerprick Tacrolimus Creatinine
Mitra v Fingerprick Tacrolimus Creatinine
Patients with kidney transplant have blood tests very often. This is normally done in
 hospital and using a needle inserted into the vein. Two tests are important for kidney
 transplant patients - creatinine to monitor the health of the kidney; and tacrolimus to
 measure the level of the medicine which prevents rejection. The investigators would like to
 compare a fingerprick microsampling method to the standard venous blood. The fingerprick test
 is the same done by patients with diabetes and we use a microsampling tip which looks like a
 cotton bud to draw up a small amount of blood. Each tip draws up exactly 10 microlitres which
 is two drops. The investigators want to compare the results of creatinine and tacrolimus done
 through the two methods. In the future, this would allow patients to do their creatinine and
 tacrolimus test at home. The tips dry completely and can be posted to a laboratory. We hope
 this will make life easier for transplant patients and also help them engage more with the
 care of their condition.
