How the Test Works

The test involves a strip that reacts with any yeast present in your sample. When yeast is detected, the strip may change color or show a positive result, indicating the presence of yeast organisms.

What Does This Test Measure?

This screening test detects the presence of yeast (Candida) in your bodily fluids, such as blood, urine, or other samples. It is not a quantitative test and does not provide exact counts of yeast.

When Might You Need This Test?

You might need this test if you have symptoms like unusual discharge, itching, or signs of infection, or if your healthcare provider suspects a yeast infection after reviewing your medical history or other test results.

Common Uses and Indications

This screening test is often used to identify potential yeast infections in patients with symptoms such as persistent thrush, vaginal discharge, or skin rashes. It can also be part of a broader diagnostic workup for suspected fungal infections.

Frequently asked questions

What does a positive result mean?
A positive result suggests the presence of yeast in your sample, which may indicate a yeast infection. However, this test is a screening tool and may not confirm the diagnosis definitively. Further testing or evaluation by a healthcare provider is usually needed to confirm the infection and determine the best treatment.
What does a negative result mean?
A negative result means no yeast was detected in the sample during this screening. However, it does not rule out a yeast infection entirely. If you have symptoms, your healthcare provider may recommend additional tests or follow-up evaluations.
Can this test be used for all bodily fluids?
This test is primarily used for screening in bodily fluids like urine, blood, or other samples collected from the body. The specific application can depend on clinical context and the healthcare provider’s instructions.
