We hypothesized that a new test using behenic acid (behenate test) as a nonabsorbable lipid marker may provide a facile means to assess fat absorption. The study proposed to answer 2 questions: first, whether the behenate test correlated with the gold standard and, second, whether the CFA improved when taking pancreatic enzymes during meals instead of taking them before meals.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and Methods:<\/jats:title><jats:p>The study compared the behenate test with the gold standard in 15 patients with cystic fibrosis during 3 arms that require 3\u2010 to 4\u2010day hospitalization: first, taking pancreatic enzymes before meals; second, taking it during meals; and third, without taking it.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>The mean CFA was 78.3% when pancreatic enzymes were taken during meals and 80.4% when these enzymes were taken before meals.

Although the CFA correlates with the behenate test, the correlation is not robust enough to justify replacement of the gold standard by this test. It is unclear whether the poor correlation between tests relates to intermeal variability in fat excretion or other factors; however, the behenate test may be suitable as a screening test for the detection of fat malabsorption.<\/jats:p><\/jats:sec>","DOI":"10.1097\/mpg.0b013e3181b18308","type":"journal-article","created":{"date-parts":[[2010,3,19]],"date-time":"2010-03-19T08:44:58Z","timestamp":1268988298000},"page":"441-446","source":"Crossref","is-referenced-by-count":17,"title":["Fat
