- Fasting glucose / HbA1c: To evaluate for diabetes mellitus, which is associated with peripheral neuropathy and CTS.
- Vitamin B12 levels: To rule out concomitant neuropathy.
- Rheumatologic markers (ESR, CRP, ANA, RF): May be obtained if inflammatory arthritis (e.g., rheumatoid arthritis, lupus) is suspected.
