What is this test?
The Aspergillus flavus DNA test is a molecular diagnostic test that detects the genetic material (DNA) of Aspergillus flavus, a type of mold, in your blood serum. The test uses a technique called Nucleic Acid Amplification (NAA) with probe detection, which makes it highly sensitive and specific for identifying this fungal pathogen.
How is the test performed?
A blood sample is drawn from a vein in your arm. The serum (the liquid part of blood) is separated and tested in a laboratory using specialized molecular biology techniques. The NAA method copies small fragments of fungal DNA millions of times, making it possible to detect even very small amounts of the fungus. A probe then specifically identifies the Aspergillus flavus DNA sequence.
Why might I need this test?
Your doctor may order this test if you have symptoms of a fungal infection, particularly if you have a weakened immune system. People at highest risk include patients with leukemia, organ transplant recipients, those on long-term steroids, or individuals with HIV/AIDS. Early detection is crucial for prompt treatment and better outcomes.
What do the results mean?
Results are typically reported as 'Detected' or 'Not Detected.' A 'Detected' result means that Aspergillus flavus DNA was found in your blood, indicating an active fungal infection that requires medical treatment. A 'Not Detected' result means no fungal DNA was found, though this does not completely rule out infection if symptoms persist.
