Synovial Fluid for Fungus Stain/Fungal Smear (KOH)

Specimen Required

SYNOVIAL FLUID

Fasting Required

Purpose of the Test

The test is performed to detect the presence of fungal elements, such as hyphae, spores, or yeasts, in the synovial fluid. It helps to diagnose fungal infections in the joints, which can cause symptoms such as joint pain, swelling, stiffness, and decreased range of motion. Early diagnosis and treatment of fungal arthritis can prevent joint damage and improve the outcome.

When this test is required

The test may be requested when a person has symptoms of a fungal infection in the joints, such as joint pain, swelling, or stiffness, especially if the person has risk factors for fungal infections, such as a weakened immune system or recent surgery. The test may also be requested when other tests, such as bacterial cultures or blood tests, have not identified the cause of the joint symptoms.

What the Test Detects

Synovial fluid for fungus stain/fungal smear (KOH) test is used to detect the presence of fungi in the synovial fluid, which is the fluid that lubricates and cushions the joints. The test examines the sample of synovial fluid for the presence of fungal elements, such as hyphae, spores, or yeasts.

Preparation for the Test

There are no specific preparations required for a synovial fluid for fungus stain/fungal smear (KOH) test. However, it is important to inform the healthcare provider if you are taking any medications, have any medical conditions, or are allergic to any medications or substances. It is also important to follow the healthcare provider’s instructions on how to prepare for the joint aspiration procedure. After the procedure, the joint may be immobilized for a short period, and pain relief medication may be prescribed.
