F***l egg counts derived from f***l flotation tests🔬 - are a common method for determining parasite levels in horses, which can then influence how often a particular horse is wormed and what class of wormer to administer. As helpful as this information is - it unfortunately does not tell us the whole story. F***l tests will not identify Pin Worms, Bots or Neck Threadworms. These parasites either do not reside in and/or lay eggs in the digestive tract making it impossible to detect their presence from a f***l sample.
Adult Tapeworms and Ascarids, despite residing in the digestive tract, can go undetected if adult worms present are not actively shedding eggs🥚 at that point in their reproductive cycle🔄. In addition, a f***l egg count cannot reveal evidence of an existing population of Encysted Small Strongyles or Ascarid and Large Strongyle migrating larvae or immature adults within the horse.
