Measurement of immunoglobulins in seminal fluid with modified nephelometry--an alternative diagnostic tool for chronic prostatitis.

The objectives of the study were to investigate the feasibility of the modified nephelometry technique to measure immunoglobulin G and A in seminal fluid and to evaluate their use in diagnosis and follow-up of chronic prostatitis.IgG and A in seminal fluid of healthy individuals (HI) and chronic prostatitis patients (CP) were measured with modified nephelometry. The literature values were confirmed. IgG reflects the long-term healing process of chronic prostatitis. IgA was significantly increased in patients with exacerbation of the disease. Nephelometry proves to be a reliable and inexpensive test to obtain IgG and IgA in seminal fluid. IgG and IgA are useful as objective parameters to confirm subjective symptom scores in a chronic prostatitis research setting.
