Voltage-Gated Calcium Channel Antibodies

Blood Sciences Test


Specimen

Serum

Special Instructions

Minimum sample volume: 3 ml

Test Usage

The assay is positive in approximately 85% of patients with the Lambert Eaton myasthenic syndrome (with or without small cell lung carcinoma SCLC) and in about 30% of Cerebellar ataxia with SCLC. Calcium channel antibodies are rarely found in patients without myasthenic symptoms, except at low titre in a few cases with small cell lung cancer. This is because small cell lung cancers express this voltage gated calcium channel.
