Investigating Back Discomfort with a Kidney Function Blood Investigation
A [kidney function blood test](https://www.privatebloodtestslondon.co.uk/kidney-function-test) is a diagnostic screening that measures specific biomarkers including creatinine, urea, and estimated glomerular filtration rate (eGFR) to assess how well your kidneys are filtering waste products from your blood. When experiencing persistent back discomfort, particularly in the lower back or flank area, kidney function testing may help identify underlying issues that could be contributing to your symptoms.
