What technology does the i-STAT Alinity v utilize?

The core measurement technology of the i‑STAT Alinity v system is in the micro-fabricated electrochemical sensors located in the i‑STAT single-use disposable cartridges. A group of thin film electrodes located at the top of a cartridge are coated with chemically sensitive films. These coated sensors react to small changes caused by chemical reactions in the sample. The sensors are either potentiometric, measuring changes in the electric potential, amperometric, measuring changes in electric current, or conductometric measuring changes in conductivity. The concentration of the analyte is determined by measuring the difference in signal from the calibrant and the sample. This difference in signal is then converted to the specific concentration units for the analyte using the analyzer's internal processor.

What kinds of tests can be run on the i-STAT Alinity v instrument?

The I-STAT Alinity v offers a variety of disposable, single-use cartridges (7) including tests for acid/base analysis, blood gases, chemistry, hematology, electrolytes, and some specialty tests like Lactate. These cartridges are configured with parameters that can give insight into patient's condition depending on the clinical situation.

What type of sample is used?

Whole blood samples without anticoagulant or whole blood collected into lithium heparin may be used.

What is the shelf-life of the i-STAT Alinity v cartridges?

The cartridges are manufactured with 5-11 months shelf life, depending on the stability of the analytes in each cartridge.

What species does the i-STAT Alinity v have reference ranges for?

Dog, cat, and horse. 

What analytes on the i-STAT Alinity v system are measured and which are calculated?

Measured: Hematocrit (Hct), Blood Urea Nitrogen (BUN), Creatinine (Crea), Ionized Calcium (iCa), Glucose (Glu), Chloride (Cl), Sodium (Na), Potassium (K), pH, Partial pressure of carbon dioxide (pCO2), Partial pressure of oxygen (pO2), and Lactate.
