Macroscopic Examination

As well as confirming and identifying the presence of worms, the Macroscopic Examination can also assess the colour and consistency of the stool sample. It should normally be brown due to pigments formed from bile, however certain conditions, foods and supplements can influence this. A stool should ideally contain about 75% water while being formed and soft. Variations to this can be determined by transit time and water absorption, thus giving insights into digestive function.
