You will be given a definition of a task first, then some input of the task.
Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Context: To evaluate whether calcium adjusted for albumin can be used to monitor calcium homeostasis in critically ill patients.', 'Prospective single-single center observational study.', 'Clinical laboratory and critical care unit of a regional teaching hospital.', 'Fifty-three paired samples were from 36 patients requiring intensive care treatment.', 'None.', 'Total calcium, albumin-adjusted calcium, and ionized calcium were measured in critically ill patients during an 8-wk period. Calcium was adjusted for albumin using the formula that is most frequently used in The Netherlands. Using ionized calcium as the gold standard, albumin-adjusted calcium overestimated hypercalcemia and totally missed hypocalcemia. The same seemed to be true for other formulas used for albumin or protein adjustment of calcium concentrations.
Answer: Albumin-adjusted calcium cannot be used in an intensive care setting to monitor reliably the calcium levels in critically ill patients and should be replaced by measurement of ionized calcium.
Output:
Is albumin-adjusted calcium suitable for diagnosis of hyper- and hypocalcemia in the critically ill?
