Detection of galactomannan in blood is used to diagnose invasive aspergillosis infections in humans. This is performed with monoclonal antibodies in a double-sandwich ELISA; this assay from Bio-Rad Laboratories was approved by the FDA in 2003 and is of moderate accuracy.

What is Histoplasma Galactomannan?

Histoplasma capsulatum is a pathogenic dimorphic fungus of worldwide distribution endemic to the Ohio and Mississippi river valleys in the United States and to certain regions of Central and South Americas.

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. Connolly PA., Durkin MM, LeMonte AM, Hackett EJ, Wheat LJ. Detection of Histoplasma antigen by a quantitative enzyme immunoassay.

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.
