Delta checks are essential for detecting significant changes in laboratory results as they involve comparing a patient's current test results with their previously collected results. By identifying variations or trends over time, delta checks help healthcare providers recognize potential abnormalities or clinically significant changes that may require further investigation or intervention. This process enhances patient safety by ensuring that any drastic changes in laboratory values are noted and addressed promptly.

While informed consent and patient consent are important for ethical practices surrounding patient care, they do not play a direct role in monitoring laboratory results. Quality control processes are crucial for ensuring the accuracy and reliability of tests but do not specifically focus on tracking individual patient result changes over time. Delta checks provide a direct mechanism for evaluating ongoing patient health through comparative analysis, thereby making them integral in clinical settings for fostering quality patient care.
