calculated red blood cell Na-K-Cl cotransport activity bumetanide-sensitive red blood cell K+ import rate 2021-11-02T16:39:33Z CMO:0003859 Measurement of the amount of potassium ion that is blocked from being imported by bumetanide inhibition of the erythrocyte membrane transport protein that transports sodium (Na), potassium (K), and chloride (Cl) ions across the cell membrane into erythrocytes, in a specified volume of red blood cells during a specified unit of time. Rubidium is sometimes assayed as a substitute for potassium.
