Specimen Required

DJ Stent

Fasting Required

Purpose of the Test

A fungal stain test like KOH preparation is used to detect the presence of fungal organisms in a sample, such as skin scrapings, hair, or nail clippings. It is commonly used to diagnose fungal infections of the skin, hair, and nails, such as ringworm, athlete’s foot, and nail fungus.

When this test is required

A DJ stent is requested when a healthcare provider determines that a patient has an obstruction in their urinary tract that needs to be removed or bypassed. A fungal stain test like KOH preparation may be requested if a patient presents symptoms of a fungal infection of the skin, hair, or nails, such as itching, scaling, and discoloration.

What the Test Detects

A DJ stent is not a test, it is a medical device that is placed in the ureter to treat urinary tract obstruction. On the other hand, a fungal stain test like KOH preparation is used to detect the presence of fungal organisms in a sample, such as skin scrapings, hair, or nail clippings.

Preparation for the Test

Test preparation for a fungal stain test like KOH preparation is relatively simple. The sample is collected using a sterile technique and then placed on a slide. A few drops of potassium hydroxide (KOH) are added to the slide to dissolve any non-fungal material, making it easier to see any fungal structures under a microscope. No special preparation is required for the person undergoing the test.

Sample Requirements

The sample required for a fungal stain test like KOH preparation depends on the suspected site of infection. For example, a skin scraping may be collected for a suspected skin infection, while a nail clipping may be collected for a suspected nail infection. The healthcare provider will determine the appropriate sample type and provide instructions for sample collection.

Additional Notes

It is important to follow the healthcare provider’s instructions for preparing for and undergoing a DJ stent placement procedure. It is also important to follow instructions for caring for the stent after the procedure to prevent complications. For a fungal stain test like KOH preparation, the healthcare provider will determine the appropriate sample type and provide instructions for sample collection. It is important to provide a clean and adequate sample to ensure accurate results. It is also important to note that a fungal stain test like KOH preparation may need to be confirmed by other diagnostic tests, such as a fungal culture, for a definitive diagnosis.
