Which of the following is a common lab finding in individuals with Crohn's disease during an exacerbation?

A. Low alkaline phosphatase level: ALP is associated with hepatobiliary or bone disorders and is not characteristically decreased during a Crohn’s disease exacerbation. Inflammatory bowel disease more commonly affects markers of inflammation and nutritional status. A low ALP level does not reflect the inflammatory or bleeding complications seen in active disease. B. Elevated hemoglobin: During an exacerbation, chronic intestinal inflammation and mucosal ulceration can result in blood loss through the gastrointestinal tract. Ongoing bleeding and impaired nutrient absorption often lead to iron deficiency anemia rather than elevated hemoglobin. C. Increased albumin level: Albumin is a negative acute-phase reactant and often decreases during systemic inflammation. In Crohn’s disease exacerbations, malabsorption and protein loss through inflamed intestinal mucosa can contribute to hypoalbuminemia. Elevated albumin levels are not typical in the presence of active inflammatory processes. D. Low hematocrit: Active Crohn’s disease frequently causes intestinal bleeding, chronic inflammation, and impaired absorption of iron, folate, or vitamin B12. These factors contribute to anemia, which is reflected by a decreased hematocrit. Low hematocrit levels are therefore commonly observed during exacerbations due to blood loss and nutritional deficiencies.
