What type of sample is used in i-STAT cartridges?

The i-STAT cartridge is specifically designed for the analysis of blood samples. These cartridges are utilized in point-of-care testing to quickly obtain critical information about a patient's metabolic and respiratory status, as well as to measure various blood parameters such as electrolytes, glucose, and coagulation factors. Blood samples are ideal because they can provide comprehensive insights into a patient’s physiological state in real time, allowing for prompt medical decision-making.

Other fluids such as urine, saline, or plasma are not suitable for the i-STAT system itself, as the cartridge's design is optimized for whole blood analysis, ensuring accurate and reliable results for immediate clinical assessments. This specificity is essential in emergency and critical care settings where quick and accurate testing can significantly impact patient outcomes.
