Randox Sodium Test Kit: The Randox Laboratories Ltd. Sodium Test Kit is an in vitro diagnostic reagent for the quantitative determination of Sodium in serum. Sodium is determined enzymatically via Sodium dependant 9-galactosidase activity with ONPG as substrate. The absorbance at 405 nm of the product O-nitrophenyl is proportional to the sodium concentration. Sodium measurements are used in the diagnosis and treatment of aldosteronism, diabetes insipidus, adrenal hyper-tension, Addison's disease, dehydration, inappropriate antidiuretic hormone secretion, or other diseases involving electrolyte imbalance. This Application Sheet has been developed for the Hitachi 704, 717, 902 and 911/912 Analysers and must be used by suitable qualified laboratory personnel under appropriate laboratory conditions.
Randox Electrolyte Cal 1 and 2: Randox Electrolyte Cal 1 and 2 are liquid calibrators for in vitro diagnostic use in the calibration of NA+, K+ and CL- electrodes on Hitachi systems ISE modules and Randox Enzymatic Sodium kit. The Randox Electrolyte Cal 1 and 2 must only be used by suitable qualified laboratory personnel under appropriate laboratory conditions.

§ 862.1665 Sodium test system.
(a)
Identification. A sodium test system is a device intended to measure sodium in serum, plasma, and urine. Measurements obtained by this device are used in the diagnosis and treatment of aldosteronism (excessive secretion of the hormone aldosterone), diabetes insipidus (chronic excretion of large amounts of dilute urine, accompanied by extreme thirst), adrenal hypertension, Addison's disease (caused by destruction of the adrenal glands), dehydration, inappropriate antidiuretic hormone secretion, or other diseases involving electrolyte imbalance.(b)
Classification. Class II.
