Final answer:
Albumin is a predictor of morbidity and mortality in critically ill patients, as it is key for various important physiological functions and its levels are affected in several health conditions.
Step-by-step explanation:
The protein albumin, which is the most abundant plasma protein, has been reported to be a significant independent predictor of morbidity and mortality in critically ill patients. Albumin is synthesized in the liver and is vital for transporting hormones and fatty acids, buffering pH, and maintaining osmotic pressure. It accounts for about half of the blood serum protein.
Conditions such as hepatic disorders, malnutrition, and kidney disorders can lead to decreased albumin concentration, which is associated with poor outcomes in patients. In contrast, the concentration of albumin can increase in dehydration and insulin-resistant diabetes.
