Immunoglobulin G (IgG) CSF Test in UAE – Diagnostic Assessment of Intrathecal Synthesis

Executive Summary & Core Metrics

Precision & Clinical Value

Quantitative nephelometry delivering 99.9% analytical sensitivity for IgG in cerebrospinal fluid. Hospital extraction only – sample collection is conducted strictly within an accredited hospital facility; mobile home phlebotomy is disabled for safety. Next-day reporting for samples received by 4 PM. Price: 180 AED. Post-result tele-guidance available via board-certified physician.

Test Overview & Methodology

The Immunoglobulin G (IgG) CSF test measures the concentration of IgG in cerebrospinal fluid to evaluate intrathecal synthesis. This assists in diagnosing multiple sclerosis, neuroinflammatory disorders, and certain central nervous system infections. The method employs rate nephelometry calibrated against LC-MS/MS reference standards, ensuring high specificity and freedom from common serum protein interferences.

Feature	Our Test (Nephelometry, ISO 9001)	Alternative (ELISA / Manual)
Precision	99.9% Sensitivity	~95% Sensitivity
Methodology	Nephelometry (LC-MS/MS calibrated)	ELISA, prone to matrix interference
Reporting Speed	Next-day (sample by 4 pm)	2–3 days

Physician Insight & Safety Protocols

“Elevated CSF IgG must always be interpreted alongside oligoclonal banding and clinical presentation. This quantitative result is one piece of the neurological puzzle, not a standalone diagnosis. Share the full report with your treating neurologist for integrated clinical decision-making.” — Dr. Ajay Singh, General Practitioner, DHA Registration ID: 36234132

Important Medication Advisory

Safety Exclusion Criteria & Emergency Red Flags

Active CNS infection (e.g., meningitis, encephalitis) – defer testing until clinically resolved.
Recent lumbar puncture complications such as spinal hematoma or post-dural puncture headache not relieved by conservative measures.
If you experience severe headache, neck stiffness, altered consciousness, or new neurological deficits after sample collection, seek immediate emergency care.

Exclusion Criteria for CSF Collection

Hospital Extraction Only – Sample collection is conducted strictly within an accredited hospital facility; mobile home phlebotomy is disabled for safety. Patients with known coagulopathy, intracranial mass effect, or local infection at the puncture site are excluded until the contraindication is resolved.

Patient FAQ & Clinical Guidance

1. What does an elevated IgG index in CSF indicate?

An elevated CSF IgG index indicates intrathecal immunoglobulin synthesis, commonly associated with multiple sclerosis, neuromyelitis optica spectrum disorders, or chronic CNS inflammation. Correlation with oligoclonal bands and MRI findings is essential for accurate diagnosis.

2. Is fasting required before a CSF IgG test?

No fasting or special dietary preparation is needed. The lumbar puncture must be performed under sterile conditions by a qualified clinician. Patients should remain well hydrated before the procedure.

3. How is the sample collected and transported?

A sterile CSF sample is obtained via lumbar puncture performed at a hospital. The specimen is immediately refrigerated and transported under cold-chain conditions to the laboratory to preserve IgG stability and prevent proteolytic degradation.

4. When will I receive my results?

Results are reported the next business day when the sample is received at our laboratory before 4 PM. Urgent requests can be expedited; please contact our clinical coordination team for details.
