Please note that i-Stat testing is only available at sites which have an i-Stat analyser. This assay may not be available at all healthcare facilities.

iSTAT Chem 8 Profile measures the following analytes:

• Potassium (K)
• Sodium (Na)
• Chloride (Cl)
• Ionized Calcium (ICA)
• Glucose
• Urea
• Creatinine
• Total CO₂ (TCO2)
• Haematocrit (Hct)
• Haemoglobin (Hb) (calculated analyte)
• Anion Gap (calculated analyte) 

The i-STAT System uses direct (undiluted) electrochemical methods. Values obtained by direct methods may differ from those obtained by indirect (diluted) methods.

Collect to recommended fill volume by tube manufacturer.

Underfilling blood collection tubes may also cause decreased TCO₂ results.

Care must be taken to eliminate “bubbling” of the sample with a pipette when filling a cartridge to avoid the loss of CO₂ in the blood.

Sample must be tested within 30 minutes of collection.
