Candida Hemolysin Detection by Probe (Urinalysis)
This test checks for the presence of Candida hemolysin, a substance produced by certain yeast infections (such as *Candida*) in your urine, using a specialized probe method.

What Is This Test Measuring?
Candida hemolysin is a protein that yeast (like *Candida albicans*) can produce. This test detects its presence in urine, which may indicate an infection or an immune response. Hemolysin can break down red blood cells, and detecting it can help assess whether yeast-related activity is occurring in your urinary tract.
Why Might You Need This Test?
This test may be used in specific clinical scenarios where yeast infections are suspected but standard urine cultures are inconclusive. It helps evaluate whether hemolytic activity is contributing to symptoms like blood in urine or other signs of infection.
How Is the Test Performed?
A small urine sample is collected, and a probe-based assay is applied to detect hemolysin. The probe reacts if the substance is present, providing a qualitative (yes/no) result. No fasting or special preparation is required.
What Does a Positive Result Mean?
A positive result suggests the presence of Candida hemolysin in your urine, which may indicate active yeast infection or immune response. This does not confirm a diagnosis alone but may support further investigation (e.g., urine culture) for yeast-related urinary tract issues.
Reference range
Negative (Candida haemulonii DNA not detected)N/A
No fasting required. Specimen should be collected prior to initiation of antifungal therapy when clinically feasible. Standard aseptic technique must be used to prevent contamination during blood collection.

Frequently asked questions
Candida hemolysin detection is not a routine test but may be used in cases of recurrent urinary tract infections, unexplained hematuria, or when yeast cultures are negative but symptoms persist. It helps differentiate between bacterial and fungal causes of hemolysis in urine.
A positive result could be due to an active *Candida* urinary tract infection, immune-mediated hemolysis, or contamination from vaginal yeast infections (if applicable). It may also occur in people with weakened immune systems or those on long-term antibiotics.
No, this test is qualitative and not a definitive diagnostic tool. It provides supporting evidence but should be combined with urine culture, clinical symptoms, and other diagnostic tests for accurate diagnosis.
