Paraneoplastic Neurological Syndromes (PNS) are rare autoimmune disorders triggered by an immune response to cancer, leading to severe neurological symptoms that often precede tumor detection. At Southern Medical Supplies Limited (SMSL), we provide a specialized portfolio of PNS diagnostic tests that detect onconeural antibodies such as anti-Hu, anti-Yo, anti-Ri, anti-Ma2, and anti-amphiphysin, which are critical for early diagnosis and tumor association. Our range includes ELISA, immunoblot, immunofluorescence, molecular, and biomarker assays from trusted global partners including EUROIMMUN, Ansh Labs, Randox, Streck, and Bio-Rad, ensuring high sensitivity, specificity, and reproducibility. These advanced diagnostic solutions support clinicians in confirming diagnosis, identifying underlying malignancies, and guiding timely therapeutic interventions, ultimately improving patient outcomes in PNS management.
