Test Overview & Methodology
The Arginase Test quantifies arginase enzyme activity in red blood cells, enabling early identification of arginase deficiency (ARG1)—a rare urea cycle disorder. This gold‑standard functional assay remains diagnostic even when plasma amino acids are equivocal.
| Feature | Our Arginase Test (ISO 9001:2015) | Closest Alternative (Routine Enzyme Assay) |
|---|---|---|
| Precision | Coefficient of Variation <3% | 5–10% CV |
| Method | Spectrophotometry (urea/ornithine detection) calibrated to WHO standards | Spectrophotometry without ISO traceability |
| Turnaround | Sample Mon by 4 pm → Report Thu (3-day TAT) | 5–7 working days |
| Sample Handling | Cold-chain refrigerated transport, no freeze/thaw cycles | Often frozen or ambient, risking enzyme degradation |
Physician Insight & Safety Protocols
“Arginase deficiency often manifests after infancy with spasticity, seizures, and failure to thrive. A borderline result does not exclude the diagnosis; always correlate with plasma amino acids, ammonia, and molecular genetics. Early dietary management can dramatically improve neurodevelopmental outcomes. – Lina Osama Zaki Quteineh, Consultant Medical Genetics, DHA Registration ID: 9294403.”
Advisory – Important Medication & Dietary Note
⚠️ Medication Warning: Do not discontinue prescribed medication or modify dietary therapy without consulting your treating physician. This test is a diagnostic aid and not a substitute for clinical evaluation.
Exclusion Criteria & Emergency Red Flags
- Exclusion: Sample hemolyzed, clotted, or transported at incorrect temperature; EDTA tube with insufficient volume (less than 3 mL).
- Exclusion: Patient currently receiving arginine supplementation or undergoing dialysis without prior wash-out period (confounds enzyme activity).
- 🚨 Red Flag – Seek Emergency Care If: Sudden lethargy, vomiting, altered consciousness, or signs of hyperammonemia (flapping tremor, breath odour like ammonia). These require immediate medical attention independent of test scheduling.
- Minor Patients: All home collections for individuals under 18 require documented parental consent as per Federal Law No. 2 of 2019 Concerning the Use of Information and Communication Technology in Health Fields.
Patient FAQ & Clinical Guidance
1. Why is the Arginase Test ordered instead of a plasma amino acid profile?
Arginase enzyme activity measured directly in red blood cells is the gold‑standard functional assay for arginase deficiency—it remains diagnostic even when plasma amino acids are equivocal or affected by dietary factors.
2. Can the test be performed at home without compromising sample quality?
Our mobile phlebotomy team uses ISO 9001:2015 certified refrigerated transport containers, maintaining the sample at 2–8°C without freezing, thus preserving enzyme activity. Collections are available daily from 8 AM to 11 PM across all Emirates.
3. What does an abnormal result mean for my child’s long-term health?
An abnormally low arginase activity, when confirmed by a second test and correlated with ammonia and genetic findings, indicates arginase deficiency—prompt dietary protein restriction and nitrogen‑scavenging therapy can prevent irreversible neurological damage. Early diagnosis and dietary management improve neurodevelopmental outcomes significantly.
