The most common way that healthcare providers test for Valley fever is by taking a blood sample and sending it to a laboratory to look for Coccidioides antibodies or antigens. Healthcare providers may do imaging tests such as chest x-rays or CT scans of your lungs to look for Valley fever pneumonia.
Which two antibodies does an EIA testing for Coccidioides detect?
We use this test to detect both coccidioidal IgM (sometimes referred to as coccidioidal precipitins) and IgG (sometimes referred to as coccidioidal CF or Complement Fixation) antibodies.
Do you always test positive for Valley Fever?
The titer that is reported to your physician is the last positive dilution. While positive serological results almost always mean that a patient has Valley Fever, a third or more of patients with Valley Fever may actually have negative results. Therefore, it may be necessary to repeat the serologic test periodically.
What is Coccidioides antibody?
Coccidioides complement fixation is a blood test that looks for substances (proteins) called antibodies, which are produced by the body in reaction to the fungus Coccidioides immitis. This fungus causes the disease coccidioidomycosis.
What is Coccidioides antibody IgG?
The presence of IgG antibody parallels the CF antibody and indicates an active or a recent asymptomatic infection with Coccidioides immitis; however, antibody may persist after the infection has resolved. An equivocal result (a band of non-identity) cannot be interpreted as significant for a specific diagnosis.

What happens if valley fever goes untreated?
Some may develop a rash. It’s easy to dismiss these symptoms, even if they linger for weeks or months. For many, the symptoms will disappear on their own. But for some, untreated Valley Fever can lead to chronic fatigue, severe weight loss, pneumonia, meningitis or even death.
What is Coccidioides AB?
Clinical Information. Coccidioidomycosis (valley fever, San Joaquin Valley fever) is a fungal infection found in the southwestern US, Central America, and South America. It is acquired by inhalation of arthroconidia of Coccidioides immitis/posadasii. Usually, it is a mild, self-limiting pulmonary infection.
What is a Coccidioides screen?
Coccidioides Screen (Cocci IgM & IgG) w/reflex Confirm (IMDF) 1062 This screening test is a qualitative antibody test that provides both IgM and IgG Cocci results. Reactive results will be confirmed via immunodi usion (at an additional charge).
