Intended Use
HiChem® ISE Electrolyte Buffer, when used in conjunction with the HiChem® ISE Electrolyte Reference, HiChem® CO2 Acid Reagent, HiChem® CO2 Alkaline Buffer, HiChem® Wash Concentrate, and HiChem® Calibration Standards, is intended for the quantitative determination of sodium, chloride, and total CO2 in serum and plasma, and sodium, potassium and chloride in urine, and chloride in cerebrospinal fluid on the Beckman® CX® and CX® DELTA Systems. On appropriately configured SYNCHRON® CX® DELTA Systems, HiChem® ISE Electrolyte Buffer will also determine calcium in serum, plasma and urine. Sodium results are for 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 antidiurelic hormone secretion, or other diseases involving electrolyte balance. Potassium results are used to monitor electrolyte imbalance in the diagnosis and treatment of diseases and conditions characterized by low or high blood potassium levels. Chloride results are used in the diagnosis and treatment of electrolyte and metabolic disorders such as cystic fibrosis and diabetic acidosis. Carbon dioxide results are used in the diagnosis and treatment of numerous and potentially senous disorders associated with changes in the body's acid-base balance. Calcium results are used in the diagnosis and treatment of parathyroid diseases, chronic renal disease and tetany (intermittent muscular contractions or spasms). This reagent is intended for professional use only.

The summary describes a chemical reagent kit for use with existing laboratory analyzers and does not mention any computational or algorithmic components, let alone AI/ML.

No.

Explanation: This device is a reagent buffer intended for in vitro diagnostic testing to quantitatively determine various electrolytes and compounds in biological fluids. It is used to aid in the diagnosis and treatment of conditions, but it does not directly treat or prevent a disease in a living body, which is characteristic of a therapeutic device.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states that the results obtained are "for the diagnosis and treatment of" various diseases and conditions, which is a clear indicator of a diagnostic device.

No

The device is a reagent (chemical substance) intended for use with specific hardware systems (Beckman® CX® and CX® DELTA Systems) to perform quantitative determinations. It is not a software-only device.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the product is "intended for the quantitative determination of sodium, chloride, and total CO2 in serum and plasma, and sodium, potassium and chloride in urine, and chloride in cerebrospinal fluid..." and "calcium in serum, plasma and urine." These are all biological specimens taken in vitro (outside the body).
  • Diagnostic Purpose: The "Intended Use / Indications for Use" section also clearly links the results of these determinations to the "diagnosis and treatment" of various diseases and conditions (e.g., aldosteronism, diabetes insipidus, electrolyte imbalance, cystic fibrosis, diabetic acidosis, acid-base balance disorders, parathyroid diseases, chronic renal disease, tetany). This indicates the results are used for diagnostic purposes.
  • Professional Use: The statement "This reagent is intended for professional use only" further supports its use in a clinical or laboratory setting for diagnostic testing.

Therefore, based on the intended use for quantitative determination of analytes in biological specimens for diagnostic purposes, this device fits the definition of an In Vitro Diagnostic.
