ATAGO- refractive index
Performed at authorized locations by point of care operators. Used to evaluate the concentrating and excretory function of the kidneys.

•ATAGO prism surface must be cleaned after every patient. Patient sample remaining on prism will become encrusted on the surface and will interfere with patient test results if not cleaned properly.
•If the ELI (External Light Interference) function indicates the [nnn] warning message when measuring a sample or during zero setting, shade the sample stage with your hand and repeat.
Collect a random clean catch urine sample from the patient for testing.
