Abstract
This invention relates to a correction liquid for a liquid membrane type ion-selective electrode that makes it possible to measure a ratio between a sodium ion concentration and a potassium ion concentration in urine by correcting for an influence from an ionic strength of the urine. The correction liquid comprises a sodium ion-sensitive part that selectively reacts with the sodium ion and a potassium ion-sensitive part that selectively reacts with the potassium ion, and measures a ratio between a sodium ion concentration and a potassium ion concentration in urine, and comprises the sodium ion, the potassium ion, and an electrolytic ionic strength modifier.
