Test Overview & Methodology

The IgG Synthesis Index & Rate Test quantifies intrathecal immunoglobulin G production, a critical biomarker for neuroinflammatory and autoimmune disorders of the central nervous system. By measuring IgG and albumin in simultaneously collected cerebrospinal fluid (CSF) and serum, the test computes both the IgG index and the daily intrathecal synthesis rate, enabling precise differentiation between blood-derived and locally produced IgG.

Feature	Our IgG Synthesis Index & Rate Test	Standard CSF IgG Index Only
Precision	99.9% diagnostic sensitivity via combined index + synthesis rate calculation	Only IgG Index; may miss subtle intrathecal synthesis profiles
Methodology	Immunoturbidimetry / Nephelometry (IgG) + BCG dye-binding (albumin); ISO 9001:2015 validated	Immunoturbidimetry or nephelometry alone; often lacks synthesis rate
Turnaround Time	Next-day report (sample collection daily by 4 pm)	Usually 2–3 working days
Clinical Value	Differentiates blood‑derived vs. intrathecal IgG; guides MS diagnosis, neuro‑sarcoidosis, CNS infections	Limited; no synthesis rate, requiring additional calculation

Physician Insight & Safety Protocols

Dr. Ajay Singh (DHA Registration ID: 36234132): “Elevated intrathecal IgG synthesis strongly supports a diagnosis of multiple sclerosis or related neuroinflammatory conditions. However, the IgG index must always be interpreted alongside MRI findings, oligoclonal banding, and a complete neurological assessment to minimize diagnostic uncertainty.”

Advisory & Medication Safety

Never discontinue prescribed immunosuppressive therapies, corticosteroids, or disease-modifying treatments without explicit guidance from your neurologist. Abrupt cessation may trigger a severe clinical relapse.

Exclusion Criteria & Emergency Red Flags

Active CNS infection (meningitis, encephalitis) requiring urgent isolation – test only after clinical stabilization.
Suspected raised intracranial pressure with papilledema; defer lumbar puncture until imaging clearance is obtained.
Coagulopathy or ongoing anticoagulant therapy that contraindicates lumbar puncture without specialist adjustment.
Seek immediate emergency care if you experience severe headache, visual disturbance, or focal neurological deficit after lumbar puncture.

Patient FAQ & Clinical Guidance

1. What is the IgG Synthesis Index & Rate test measuring?

This test calculates the ratio of IgG in cerebrospinal fluid relative to serum, corrected for albumin leakage, and determines the absolute rate of daily IgG production inside the central nervous system.

2. Why must CSF and blood samples be drawn simultaneously?

Concurrent collection is essential because IgG and albumin levels fluctuate independently. A time gap invalidates the index calculation and may produce misleading false-negative or false-positive results.

3. How should I prepare for the lumbar puncture and what support is provided?

No fasting is required; maintain good hydration. The procedure is performed exclusively in a hospital setting. After results are available, telephonic clinical guidance is offered to help interpret the findings.

4. Can I book this test directly and verify insurance coverage?

Yes. Direct booking and insurance verification are available via WhatsApp at +971 54 548 8731. Pre-payment is accepted to streamline the process.
