Laboratory assay overview

Blastomycosis caused by the fungus blastomyces dermatididis, occurs most commonly in men ages 20-69 years. Infection may be transient or lead to chronic, progressive pulmonary disease.

Laboratory assay overview

Although titers of 1:8 and greater are considered positive, confirmed serological diagnosis of blastomycosis by the CF test requires a four-fold or greater increase in titer between acute and convalescent specimens, and lack of corresponding titers to C. immitis and H. capsulatum. Specificity can only be demonstrated by immunodiffusion procedures. A negative CF test does not rule out the diagnosis of active blastomycosis, as less than 50% of sera from patients with proven blastomycosis are positive by this assay.

Verify these ranges and sources

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
