The Trinidad CH System is an automated, clinical chemistry analyzer designed to perform in vitro diagnostic tests on clinical specimens. The system’s chemical and immunochemical assay applications utilize photometric and ion selective electrode technology for clinical use.

The TD-LYTE Integrated Multisensor (Na, K, Cl) is intended for in vitro diagnostic use in the quantitative determination of sodium, potassium and chloride (Na, K, Cl) in human serum, plasma and urine using the Trinidad CH System. Measurements of sodium 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. Measurements of potassium obtained by this device are used to monitor electrolyte balance in the diagnosis and treatment of disease conditions characterized by low or high blood potassium levels. Chloride measurements are used in the diagnosis and treatment of electrolyte and metabolic disorders such as cystic fibrosis and diabetic acidosis.

The TD-LYTE IMT Standard A is intended for the calibration of Na, K, and Cl on the Trinidad CH System.

The TD-LYTE IMT Standard B + Salt Bridge is intended for the calibration of Na, K, and Cl on the Trinidad CH System.

The Albumin BCP Reagent (Alb_P) is intended for in vitro diagnostic use in the quantitative measurement of albumin in human serum or plasma on the Trinidad CH System. Albumin measurements are used in the diagnosis and treatment of numerous diseases primarily involving the liver or kidneys.

The Albumin BCP calibrator is for in vitro diagnostic use in the calibration of the Trinidad CH Albumin BCP Assay (AOE_P) on the Trinidad CH System.

Indications for use as stated in the FDA summary.
