What is the first step in the stool flotation technique procedure?

The first step in the stool flotation technique procedure involves weighing 4-5 grams of fresh feces. This initial measurement is crucial as it ensures that the sample size is consistent and appropriate for the subsequent processes. Accurate weighing allows for optimal dilution with the flotation solution, which is necessary for effectively separating and identifying the eggs, cysts, or larvae of parasites present in the stool sample.

Using a proper amount of feces is fundamental because insufficient sample size can lead to inadequate representation of the content, while too much material could complicate the flotation and reduce the clarity of results. Once the sample is weighed, it can be accurately mixed with the flotation solution, which is the next step in the procedure. Therefore, weighing the feces appropriately sets the stage for a successful flotation technique, contributing to the reliability of the test results.
