[The Steatocrit Test: a semiquantitative method to evaluate the fecal fat excretion--method standardization].
The main objective of this study was to introduce among us this technique. In a first step, steatocrit was compared to Van de Kamer test for 30 fecal samples. A significant positive correlation was found. In a second step, a steatocrit value was determined for normal children aged 0 to 72 months. In children from 0 to 3 months of age, no influence was found of diet (whether exclusively maternal milk or artificial one) on steatocrit value. However, upto the age of 3 months a significant and negative correlation was found between age and steatocrit value. Finally, three age groups were identified with different steatocrit values, as follows: 0-1 month, 4.04%; 1-3 months, 1.38%, 3-72 months, 0.29%. Thus the steatocrit test for fecal fat excretion was again shown to be not only simple, rapid, painless and inexpensive but also a reliable one.
