A positive and negative control should be stained at the same moment.

  1. Wash SAF-stool mixture 3 times with saline.
  2. Place a drop of Mayer's Albumine and a drop of sediment. Mix together and spread.
  3. Let smear dry and fix for 10 minutes in a 70% Ethanol bath
  4. Prepare a working solution of stain by mixing 100 ml of Haematoxylin and 100 ml of Haematoxylin Mordant.
  5. Place smear in running tap water for 2 minutes
  6. Place in Haematoxylin-Haematoxylin Mordant bath for 10 minutes
  7. Wash with distilled water for 1 minute
  8. Place in working solution bath of picric acid for 10 minutes
  9. 10 minutes in running tap water
  10. Place into 70% ethanol with ammonia for 10 minutes
  11. Place into 95% ethanol for 10 minutes
  12. Place into 100% ethanol for 5 minutes
  13. Place into another 100% ethanol bath for 5 minutes
  14. Place into Carbolxylene for 10 minutes
  15. Place into Xylene for 10 minutes
  16. Mount with Eukitt (EU-500) and examine microscopically


Use the working solution of haematoxylin for one week, then reject the remaining quantity. This is a part of identification. Other methods may be required.
