Nerve function blood tests measure biomarkers that affect the health of your nervous system. Key markers include vitamin B12, folate, homocysteine, and other nutrients vital for nerve repair, signalling, and protection. Abnormal results may be linked to neuropathy, tingling, numbness, weakness, or cognitive decline. Monitoring nerve health can help identify deficiencies or imbalances early, supporting long-term neurological wellbeing. Our nerve function panels provide valuable insights into nerve performance and overall nervous system health.
