Neuronal Nuc Ab (Ri), IFA

 

Reference Range: Negative

 

Neuronal nuclear (anti Ri) antibody is detected in patients with paraneoplastic syndrome clinically presenting with myoclonus/opsoclonus. The presence of Ri antibody strongly suggests underlying breast carcinoma, or gynecological cancer. Ri antibody is identified by IFA and confirmed by Western Blot. A negative result does not exclude the possibility of breast cancer or other malignant tumor.
