What is Sudan spots?
SUDANT stain emphasizes the fats present in the sample such as blood or feces. The test uses a family of dyes known as Sudan dyes that are brought to fat when applied to a microscope. Several dyes are available for medical testing, allowing care providers to choose the most suitable for the sample. The same dyes are also used in the production of some products.
Coloring is a common practice for pathologists and other care providers who want to evaluate the samples as effectively and reliably as possible. They use stains to highlight certain structures in the sample or to indicate specific compounds. In some cases, the stain reveals the presence of something that should not be there, while in other cases the stains make it easier to find specific phenomena of interest in the sample. In the case of Sudanese spots, the aim is to emphasize any fats present by the dye that allows the pathologist to identify their presence and estimate their concentration.
These dyes are lysochromic, mpiAdding to the sample add and colored fats. Some Sudan dyes are indiscriminate and can work on several types of fat. Others are more focused and can emphasize specific fat, such as triglyceride. The pathologists of the evaluation sample need to consider their possibilities when choosing a dye for testing to determine the best option. This may depend on why Sudan has been ordered and what the pathologist expects to find in the test.
Fecal tests of Sudan stains are used to check the symptoms of stearrhea or stool fats. This may indicate that the patient has a problem with malabsorption or abdominal disorder. Testing can also be used in blood samples in patients with suspicion of blood. The technician that performs Sudan may notice the dye used and finding, including a positive or negative indicator that fats are present and what types of fats were present. This is only a qualitative test without providing hard measurements,Although the technician can offer information about apparent concentrations in the sample.
Pathological texts and reference guides for laboratories may include pictures of different types of Sudanese stain tests. These can help technicians identify finding out of interest or concern by comparing with known samples. Control images are taken from healthy individuals and show what the test should look like if the finding is negative. Other sample images show what is happening to different types of conditions, emphasizing the findings associated with them, so pathologists know what to look for and how to identify it.
