An I-stat (I-stat CG4, CG6, CG7) is a test to evaluate the electrolytes and acid base balance of your pet’s blood stream. An I-stat is recommended as a part of most medical work-ups as it reveals critical information about your pet’s state of health. An I-stat is necessary to determine what type of fluids are necessary for intravenous use in any patient that is hospitalized or undergoing anesthesia.
If a patient has significant abnormalities on an I-stat, these abnormalities may be followed as often as every 4-6 hours to evaluate response to therapy or change in medical status.
An I-stat is done after a small amount of blood is drawn from a vein or intravenous catheter and the blood is evaluated on an in-house analyzer for immediate results.
