Egg hatch assay
Egg Hatch Assay
The Egg Hatch Assay (pronunciation: /ɛg hæʃ æˈseɪ/) is a diagnostic method used in parasitology to determine the presence and concentration of parasite eggs, particularly those of nematodes, in a given sample.
Etymology
The term "Egg Hatch Assay" is derived from the process it describes. "Egg" refers to the reproductive unit from which the parasites originate, "Hatch" refers to the process of the eggs developing into larvae, and "Assay" is a term used in laboratory contexts to refer to an investigative procedure for qualitatively assessing or quantitatively measuring the presence or amount of a target entity.
Procedure
The Egg Hatch Assay involves the collection of a sample, often fecal matter, which is then treated with a solution that encourages the eggs within the sample to hatch. The resulting larvae are then counted under a microscope, providing a measure of the concentration of parasites within the sample. This method is particularly useful for diagnosing infections of nematodes such as Haemonchus contortus, a common parasite in sheep.
