What is this test?
This blood test looks for antibodies that recognize Candida tropicalis, a type of yeast. It is qualitative, meaning the result is reported as positive or negative rather than as a measured concentration.
Why might I need this test?
The test may be ordered when a Candida tropicalis infection is suspected or when a clinician is evaluating a possible immune response to this organism. Results need to be interpreted with symptoms, medical history, and other laboratory findings.
How is the test performed?
A blood sample is collected and tested in the laboratory for antibodies to Candida tropicalis. The exact laboratory method is not specified by the test code.
How do I prepare for the test?
No special preparation is usually needed. Follow any instructions from your healthcare professional, especially if you have a bleeding disorder, are taking blood thinners, or have recently received a blood transfusion.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result indicates that antibodies to Candida tropicalis are detectable and may reflect prior exposure or an immune response. It does not necessarily mean that an active Candida tropicalis infection is causing current symptoms. A negative result does not completely exclude infection, particularly in people with weakened immune systems, so results should be reviewed by a qualified clinician.
Short name
