The Sysmex Automated Hematology Analyzer XE-5000 measures platelet count by the impedance method to quantify lamellar body counts. (Automated Hematology Analyzer XE-5000 Instructions for Use [North American Edition], Code No. 461-2638-6, Date of Last Revision: December 2011)
One-dimensional thin-layer chromatography (TLC) technique is used for separating the phospholipids in amniotic fluid. The first step in the process involves extraction of the lipids present in the amniotic fluid using chloroform/methanol mixture. The extracted specimen is streaked onto a TLC plate and placed in tank 1 for prechromatography, a step that removes a component that otherwise comigrates with phosphatidylglycerol (PG). Lipids are then separated using tank 2. The separated lipids are made visible with dilute cupric acetate and charring. Lecithin to sphingomyelin (L to S) is determined using a scanning densitometer. The relative intensities of L and S are expressed as a ratio, and PG is reported from a visual observation of the plate and reported as present, absent, or trace.(Unpublished Mayo method)
