Intended Use
The ABL90 FLEX analyzer is a portable, automated analyzer that measures pH, blood gases, electrolytes, glucose, lactate, and oximetry in heparinised whole blood. The ABL90 FLEX analyzer is intended for use by trained technologists, nurses, physicians and therapists. It is intended for use in a laboratory environment, near patient or point-of-care setting. These tests are only performed under a physician's order. Indications for use: pH, pO2 and pCO2: pH, pCO2 and pO2 measurements are used in the diagnosis and treatment of life-threatening acid-base disturbances. Potassium (cK*): potassium measurements are used to monitor electrolyte balance in the diagnosis and treatment of disease conditions characterized by low or high blood potassium levels. Sodium (cNa*): sodium measurements are used in the diagnosis and treatment of aldosteronism, diabetes insipidus, adrenal hypertension, Addison's disease, dehydration, inappropriate antidiuretic secretion, or other diseases involving electrolyte imbalance. Calcium (cCa2+): calcium measurements are used in the diagnosis and treatment of parathyroid disease, a variety of bone diseases, chronic renal disease and tetany. Chloride (cCl¯): chloride measurements are used in the diagnosis and treatment of electrolyte and metabolic disorders such a cystic fibrosis and diabetic acidosis. Glucose (cGlu): glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus and idiopathic hypoglycemia, and of pancreatic islet cell carcinoma. Lactate (cLac): The lactate measurements measure the concentration of lactate in plasma. Lactate measurements are used to evaluate the acid-base status and are used in the diagnosis and treatment of lactic acidosis (abnormally high acidity of the blood.) Total Hemoglobin (ctHb): total hemoglobin measurements are used to measure the hemoglobin content of whole blood for the detection of anemia. sO2: oxygen saturation, more specifically the ratio between the concentration of oxyhemoglobin and oxyhemoqlobin plus reduced hemoglobin. FO2Hb: oxyhemoqlobin as a fraction of total hemoglobin. FCOHb: carboxyhemoqlobin measurements are used to determine the carboxyhemoglobin content of human blood as an aid in the diagnosis of carbon monoxide poisoning. FMetHb: methemoqlobin as a fraction of total hemoglobin. FHHb: reduced hemoglobin as a fraction of total hemoglobin. Fraction of Fetal Hemoglobin (FHbF): FHbF indicates the amount of fetal hemoglobin. FHbF is seldom used clinically.
Device Description

No
The summary describes a standard automated blood gas analyzer and does not mention any AI or ML capabilities in its description, intended use, or performance studies.

No.
The device is an analyzer that measures various parameters in blood, which are then used in the diagnosis and treatment of conditions. It does not directly provide therapy or treatment itself.

Yes

The device measures various blood parameters (pH, blood gases, electrolytes, glucose, lactate, and oximetry) whose measurements "are used in the diagnosis and treatment of life-threatening acid-base disturbances" and "in the diagnosis and treatment of" specific disease conditions. This definition directly aligns with the purpose of a diagnostic device.

No

The device description explicitly states it is a "portable, automated system intended for in vitro testing of samples of whole blood," indicating it is a hardware device that performs physical measurements.

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 analyzer "measures pH, blood gases, electrolytes, glucose, lactate, and oximetry in heparinised whole blood." These are all measurements performed on biological samples in vitro (outside the body).
  • Device Description: The "Device Description" further clarifies that the system is "intended for in vitro testing of samples of whole blood".
  • Indications for Use: The detailed list of indications for each parameter (pH, pO2, pCO2, Potassium, Sodium, etc.) describes how these measurements are used in the diagnosis and treatment of various disease conditions. This aligns with the purpose of IVD devices, which are used to provide information for diagnostic purposes.

The device analyzes biological samples (whole blood) to provide information used in the diagnosis and treatment of diseases, which is the core definition of an In Vitro Diagnostic device.
