The steatocrit: A simple method for estimating stool fat content in newborn infants

Abstract

Actions of salbutamol, disodium cromoglycate, and placebo administered as aerosols in acute asthma 725Resistance to DSCG in acute asthma is greater therefore, than to salbutamol. However, clinical observation suggests that resistance to beta-2 stimulants does also increase with severity of the attack. It would appear probable that only when severity exceeds the point at which measurements can be made with a peak flow meter does resistance to salbutamol become pronounced. Although placebo effects are greater in the attack than between attacks, again no information is available about attacks severe enough to prevent measurement using a peak flow meter. pipette into a capillary tube (for this technique blood pH capillary tubes cut to the same length as standard glass capillary tubes were used). They were sealed at one end by a flame and centrifuged for 15 minutes at 12 000 g, using a haematocrit centrifuge (Hawksley, London).After centrifugation the tubes were removed immediately and placed vertically. The length of the fat layer at the top and that of the solid layer at the bottom was measured with vernier callipers to the nearest 0 05 mm. Stool fat content was expressed as a percentage (steatocrit) of the total length of the solid column in the tube (that is fat layer + solid layer) (Fig. 1). The steatocrit was measured in duplicate. The stool fat content was also measured by Sobel's method2 which requires 3 g of stool.

“…The method was initially developed as a quick technique for diagnosing fat malabsorption in 5‐day‐old infants in India (Phuapradit, Narang, Mendonca, Harris, & Baum, 1981). After implementation by Tran et al.…”

The steatocrit as a measure of fecal fat excretion: uses and pitfalls

“…9 It is akin to the determination of packed cell volume in capillary glass tubes after centrifugation except that in the steatocrit, the stool suspension separates into solid, aqueous and lipid layers. It is the latter layer which is measured in the steatocrit.…”
