What is the blood test for histoplasmosis?

What is Aspergillus antigen test?
Serum galactomannan (Aspergillus antigen) can often be detected a mean of 7 to 14 days before other diagnostic clues become apparent, and monitoring of Aspergillus antigen can potentially allow initiation of preemptive antifungal therapy before life-threatening infection occurs.
How do I know if I have histoplasmosis?
In most cases, histoplasmosis causes mild flu-like symptoms that appear between 3 and 17 days after exposure to the fungus. These symptoms include fever, chills, headache, muscle aches, cough and chest discomfort. In these milder forms, most symptoms go away on their own in a few weeks.

Is there a test to detect Histoplasma galactomannan antigen?
ALPHA Histoplasma EIA Test Kit for the Detection of Histoplasma Antigen- REF HAG102, Package Insert, Immuno- Mycologics, Inc., 2700 Technology Place, Norman, OK 73071, Revised 07/18/2011.

How often should galactomannan antigen levels be tested?
Repeat testing is recommended if the result is negative but IA is suspected. Patients at risk of IA should have a baseline serum tested and should be monitored twice a week for increasing galactomannan antigen levels. Galactomannan antigen levels may be useful in the assessment of therapeutic response.
