How long should an i-STAT cartridge be allowed to reach room temperature before use?

An i-STAT cartridge should be allowed to reach room temperature for at least 5 minutes before use to ensure accurate test results. The cartridges contain reagents that can be sensitive to temperature variations. When they are stored in a cold environment, the chemical reactions that occur during testing might not perform optimally if the cartridge is used while still cold. Allowing the cartridge to acclimate to room temperature helps to activate the reagents properly, ensuring that the test results reflect the patient's actual condition accurately and consistently. This practice is crucial in maintaining the integrity of the test outcomes and achieving reliable diagnostics in a clinical setting.
